Know little about children's teeth.

1. Tips for tooth protection

-The following is taken from the Internet. Please see for yourself-

Protect your teeth from childhood.

Let your baby know how to protect his teeth and prevent oral diseases from an early age. Generally speaking, you can educate your baby about oral health care knowledge from the age of 3.

Tell your baby simple oral health knowledge such as hygiene, love cleaning, brushing your teeth in the morning and evening, gargling after meals, eating less sweets, eating more fruits and vegetables, not eating snacks before going to bed, not being picky about food, and being partial to food, so that your baby can understand the significance of oral health care.

Mom and dad can arouse the baby's curiosity by telling stories (such as the story of a bear's tooth extraction): "Why does the bear have a toothache? How should I protect my teeth? " You can also use pictures or funny children's songs to teach your baby about teeth. For example, the teeth that grow after birth are called deciduous teeth. At the age of 5~6, deciduous teeth begin to fall off slowly and grow new teeth, which are called permanent teeth.

If a permanent tooth is decayed or knocked out, it won't grow again. Therefore, it is necessary to protect teeth from childhood, pay attention to the hygiene of teeth, and let the baby know the importance of brushing and gargling.

Warm water for brushing teeth can greatly reduce cold and heat, protect teeth and reduce the occurrence of dental diseases, especially for patients with tooth allergy, dental caries, periodontitis, oral ulcer, glossitis and pharyngolaryngitis. When the baby gets used to brushing his teeth twice every morning and evening, he can start to try to brush his teeth with toothpaste. Note that when brushing your teeth with toothpaste, rinse the toothpaste foam in your mouth with water.

Five principles of tooth protection

1, a balanced diet

Eat a balanced diet, and choose foods that are beneficial to oral health, including whole grains, milk, fish eggs, fresh vegetables and fruits. Eat less sour, sweet and sticky food, drink less sweet drinks, eat less snacks or not eat.

2. Brush your teeth in the morning and evening

Brushing teeth can remove dental plaque, which is attached to the bacterial membrane on the surface of teeth and is the main factor causing dental caries and gingival inflammation.

3. Choose your dental appliances carefully.

Choose a healthy toothbrush suitable for children and use clean and hygienic dental appliances.

Step 4 brush your teeth correctly

The correct method of brushing teeth is vertical brushing (the toothbrush is brushed along the gap between teeth): the upper teeth are brushed downwards and the lower teeth are brushed upwards; Brush left and right inside and outside, not left and right horizontally.

5, regular inspection

Go to the stomatological hospital once every six months or once a year to check your teeth, so as to achieve early prevention and early treatment.

Tips for protecting teeth

1. After brushing your teeth with fluoride toothpaste, you don't need to rinse off the foam in your mouth;

2. Chewing xylitol gum can neutralize oral acidity and prevent tooth decay, but you should brush your teeth.

3. Smoking is a high risk factor for oral cancer and periodontitis, and smoking should be stopped;

4. Regular tooth washing won't hurt your teeth. If possible, wash your teeth once every six months.

2. I know very little about teeth

A child has 20 teeth, which are called deciduous teeth. Primary teeth will be gradually replaced by permanent teeth around the age of 6. After 12- 13 years old, there are 28 permanent teeth, and after 18 years old, there are 32 third permanent molars. The protection of deciduous teeth has an important influence on the eruption of permanent teeth. If you don't pay attention to protecting deciduous teeth, it will directly affect the growth and development of permanent teeth in the future. It is often seen that some children have only black roots in their teeth, which not only affects eating, but also often causes gum swelling and pain. Inflammation and swelling of children's teeth can lead to:

First, the local inflammation caused by bad teeth will affect the growth and development of permanent tooth germs. The growth and development of permanent dentitis may lead to developmental abnormalities, such as various tooth deformities.

Second, the main manifestations of bad teeth are toothache and root swelling and pain. Toothache affects children's eating, and sometimes it affects the rest of the family at night.

Third, the bad roots are repeatedly inflamed, resulting in uneven dentition of permanent teeth.

Because children are still young, they don't know how to protect their teeth and how to develop good oral hygiene habits, so please ask parents to educate and urge their children to develop good oral hygiene habits.

1, cultivate children's good brushing habits. Brush your teeth twice in the morning and evening. Teach your baby the correct way to brush your teeth: The correct way to brush your teeth is to brush vertically. The advantages of vertical brush are: little damage to teeth, good effect on gums, and promotion of blood circulation of gums.

2. Children with dental caries should be taken to the dentist for examination and treatment in time.

3, a balanced diet, eat more fruits and vegetables, enhance the disease resistance of oral mucosa, and maintain the health of teeth and periodontal tissue.

Brush your teeth at least twice a day.

Rinse your mouth for at least three minutes at a time. Be sure to rinse it thoroughly.

Otherwise, swallowing it is not good for your stomach.

The variety of toothpaste should be changed frequently, instead of using one toothpaste all the time.

See a dentist every six months.

Brush your teeth from the inside out, brush your teeth up and down, and put an end to sawing.

Q: Why do you have a toothache?

A: Generally, toothache is very severe, which may be caused by tooth decay, bite or trauma, or even gradual necrosis of tooth nerve. At this time, the best treatment is root canal therapy. If it's just a "acupoint" medicine or a nerve killer, it's only a temporary pain relief. Moreover, it is only effective when the teeth have decayed and the tooth nerves are exposed. If it is neuralgia caused by trauma or bite, just "point" the medicine or rub it.

Q: How do you know there is tooth decay?

A: Black spots and small holes on the surface of teeth usually indicate tooth decay in enamel, but patients will not feel pain and other symptoms. When dental caries extend inward to dentin, patients will feel sore when eating cold or sour food. If dental caries further damage the pulp, it will lead to pulpitis, which will be extremely painful and even affect the whole body health.

Although tooth collision, tooth cracking, bite, abrasion, periodontal disease or contact with different metal fillings may all cause toothache. However, the most common cause of toothache is tooth decay! Of course, the best way is to see a dentist regularly every six months. Dentists will use probes to find cavities on the surface of teeth. As for some cavities near the teeth, you can check whether there are cavities by irradiating the wing-biting X-ray.

Q: Why do teeth rot?

A: Bacteria, food, host (teeth) and time are the four main factors leading to tooth decay.

Bacteria: Streptococcus mutans.

Food: The type, quantity and viscosity of sugar determine the acid production.

The shape and arrangement of teeth affect the adhesion time of food.

Time: the number of meals and the length of each meal.

The "bacteria" in dental plaque or saliva in human mouth ferment sugar as "food", which produces acid after metabolism, and contacts with "teeth" for a long time, destroying the surface of teeth and causing decalcification and dental caries, which is called tooth decay.

Q: Preventing tooth decay?

A: Now that we know the causes of tooth decay, we should take preventive measures against each cause: brush your teeth and floss your teeth immediately after eating, and thoroughly remove the residue of food, so as to get rid of the "food" factor! Reduce the chance of plaque formation and try to keep "bacteria" and "food" from meeting! The "teeth" were not soaked in a dirty environment for a long time, which reduced the occurrence of tooth decay. Having said that, please go to the dental clinic for a health check-up regularly!

3. What are some tips for children to protect their teeth?

Tips for protecting children's teeth: 1. Feeding should be regular and quantitative, so that children can develop good eating habits from an early age, strengthen the digestive function of the gastrointestinal tract, and digest and absorb well, so that teeth can grow healthier. This is a virtuous circle.

2. Overcome the habit of partial eclipse, ensure balanced nutrition, add complementary food to the baby in time, correct the baby's bad habit of partial eclipse, and ensure the baby's adequate and balanced intake of nutrition, thus ensuring the normal structure and shape of teeth and improving the resistance of teeth to dental diseases. In addition, the baby's deciduous teeth should be supplemented with nutrients such as calcium, phosphorus and vitamin C, which can promote the development and calcification of baby's teeth, ensure the health of periodontal tissue and reduce the possibility of dental lesions.

3, develop a correct breastfeeding posture Some babies will form mandibular protrusion or retraction due to incorrect posture or improper bottle position during breastfeeding. If this happens for a long time, the baby's teeth and jaws will be deformed, which will not only affect the baby's beauty, but also affect the development of chewing function.

When the baby is nursing, the best posture is half lying, the bottle is at a 90-degree angle with the mouth and lips, and the nipple does not oppress the upper and lower lips. 4. Let your teeth exercise. Babies in teething period especially like to bite or bite hard things. This is because the deciduous teeth grow out and squeeze the periphery, which makes the gingival tissue feel itchy and painful.

At this time, the mother can let the baby chew some hard things, such as biscuits, toast, apple slices, carrot slices and so on. On the one hand, it can relieve the discomfort of gums, on the other hand, it can exercise masticatory muscles and promote the development of teeth and jaws.

4. It is better for tabloids to have pictures about love teeth, as well as knowledge about love teeth, all of which are related to this.

Nowadays, oral health has long been an important part of people's overall health and quality of life, and it is also an indispensable pillar to prolong people's healthy life.

Protecting and strengthening teeth is not only regarded as the top priority of oral health, but many fashionistas are even proud of their names. According to textual research, the Book of Rites written by Confucius and compiled by later generations records that "the chicken crows at first and is washed with salt", which shows that our people have been gargling with salt water every morning at the end of the Spring and Autumn Period.

This method of tooth protection is also described in A Dream of Red Mansions written by Cao Xueqin, a literary giant in China18th century. Miss Lin Daiyu, a rich girl, wipes her teeth with green salt before and after going to bed every night. It can be seen that gargling with salt water is a common method to protect teeth in ancient China.

The historical record of brushing teeth was written by Tang dynasty, and the ancient medical book "The Secret of Outer Taiwan" written in 752 AD recorded the ancient prescriptions before Tang dynasty and some new prescriptions at that time. It has been mentioned that biting off one end of a poplar branch and wiping it with medicine can make the teeth "fragrant and smooth". This should be the earliest habit of brushing teeth in China, and ancient murals in Dunhuang also have pictures of wiping teeth with fingers.

Moreover, it is said that China was the first country to use toothbrushes, which can be verified in the cultural relics unearthed from the ancient tombs of Liao. The earliest toothbrush in the world appeared in China. Ancient monks also mastered this tooth protection technology. The Buddhist sutra Hua Yan Jing even concluded that chewing poplar branches has 65,438+00 benefits, including "removing tartar" and "making the mouth fragrant".

Monks should clean their teeth like this before chanting. Li Shizhen, a famous doctor in Ming Dynasty, also pointed out in his magnum opus Compendium of Materia Medica that cleaning teeth with tender willow branches is infinitely useful.

● What foods can prevent dental caries? Fish, rice, lentils, peas and broad beans have high phosphorus content, and phosphate can form a buffer system to prevent excessive acidification of the mouth. Children should eat more foods rich in calcium, such as beans, bean products, vegetables, fish and shrimp. So as to provide enough minerals and vitamins for the normal development of teeth.

Milk and dairy products contain a lot of calcium, which can inhibit the acid production of bacteria and prevent the dissolution of calcium and phosphorus compounds in teeth. In addition, immunoglobulins and enzymes contained in milk can inhibit the growth of bacteria in the mouth.

Foods containing more fluorine include fish, shrimp, kelp, jellyfish, tea and mineral water. Fluorine can form insoluble fluorapatite with calcium and phosphorus compounds in dentin, thus preventing the acid produced by bacteria from eroding dentin. You should eat more foods that are not overcooked, because they contain more fat-soluble vitamins and minerals and need more chewing power when eating. Chewing can promote saliva secretion, help digestion and clean teeth.

You should eat less refined food (such as plum, chocolate, soda, candy, cakes, biscuits, etc.). ). Fruits, such as apples and pears, can play the role of mechanically scrubbing teeth when eaten, and wipe off bacteria attached to the surface of teeth.

In addition, pectin in fruits can also inhibit bacteria. Vegetables contain many trace elements and a lot of vitamin C, and are also very important anti-caries nutrients.

Plant fiber can reduce the adhesion of food and the formation of dental plaque through mechanical friction cleaning of tooth surface and secretion of salivary glands. In addition, vegetable oil can form a hydrophobic layer on the surface of teeth to protect teeth and prevent dentin from dissolving.

■ Simple method → The method of whitening teeth with lemon juice is as follows: After brushing your teeth every night, touch some lemon juice with gauze and rub your teeth, and your teeth will become white and bright. Lemon has a strong cleaning power and whitening effect, and contains vitamin C, which can strengthen the roots of teeth.

Students should protect their teeth and do the following: 1. Develop a good habit of brushing your teeth. Rinse your mouth with warm water after meals and brush your teeth once in the morning and evening.

Don't brush your teeth too often, it will damage your teeth, and don't brush your teeth for too long. 2. Pay attention to oral hygiene and protect your teeth.

Eat less candy at ordinary times. Especially don't eat sugar before going to bed to prevent dental caries.

In addition, we should pay attention to the usual hygiene habits, do not bite fingers, do not bite pencils and other foreign bodies, and do not lick your teeth with your tongue. 3. If your teeth are sick, you should seek medical advice in time.

If there are cavities, they should be repaired or pulled out. It is not difficult to achieve the above points, the key is perseverance.

May all students have healthy and beautiful teeth. 1. Develop good eating habits: reduce the frequency of eating sugary foods, because many bacteria will accumulate on the edges of teeth and gums, and bacteria will produce acid when using sugar, which will corrode teeth and cause dental caries.

2. Establish good oral hygiene habits: keep oral hygiene clean, master the correct method of brushing teeth, rinse your mouth after meals, and brush your teeth in the morning and evening. 3. Correct brushing angle and action: tilt the toothbrush at 45 degrees and press it between the tooth surface and gums. Brush as far as possible into the gingival sulcus and between the teeth, then brush vertically along the teeth, and gently turn the brush head, not too hard. Brush each tooth in turn for three minutes each time.

4. Brush the outside of teeth: clean the outside of upper and lower teeth with correct brushing action and appropriate angle. Brush the upper teeth from top to bottom and brush the lower teeth from bottom to top. Each part can be brushed 4-6 times repeatedly. 5, the inside of the toothbrush: still follow the principle of brushing vertically along the teeth and gently rotating, don't just pay attention to the outside of the toothbrush, don't pay attention to the cleaning of the inside of the teeth.

6, the chewing surface of brushing teeth: with adaptability, brush the chewing surface of the upper and lower teeth in the front and back direction. 7, pay attention to the back teeth: the teeth behind the mouth also need the same attention, after cleaning all the teeth, rinse your mouth with water.

8. Choose health care toothbrush and fluoride toothpaste: the bristles of health care toothbrush are soft and elastic, and do not damage teeth and gums. Fluorine in fluoride toothpaste is combined with enamel, which makes teeth stronger and has good caries prevention effect.

5. What are the tips for dental care?

If you want to protect your teeth, you must first understand the structure of your teeth.

Teeth are the hardest organs in the human body. It has the functions of biting, tearing, grinding food and assisting pronunciation.

There are two pairs of teeth in a person's life: one pair is deciduous teeth, the upper and lower jaws have 20 teeth, and 10 teeth. It began to erupt about half a year after birth and came out about two and a half years old. From 7 years old to 12, deciduous teeth fall off one after another. The other pair is permanent teeth, with 32 teeth in the upper jaw and 65,438+06 teeth in the lower jaw. The deciduous teeth gradually change from the age of 6, and all the permanent teeth erupt around the age of 12 except the third molar.

The third molar usually erupts after the age of 20, also called wisdom tooth. Wisdom teeth will never come out, so 28~32 permanent teeth are normal.

Teeth are divided into three parts: crown, neck and root. The crown is the part we can see, and it is the part where the teeth are exposed outside the gums.

The surface of the crown is covered with a layer of enamel, which is the hardest tissue in the human body, and its hardness is similar to that of the time. The root is embedded in the alveolar process of the upper and lower jaws.

The root surface is covered with a layer of cementum. The neck of the tooth is a slightly thinner part between the crown and the root of the tooth, which wraps the gum.

Teeth are mainly composed of dentin, and the internal cavity is called tooth cavity. The cavity of movable teeth is filled with connective tissue, nerves and blood vessels, which are collectively called dental pulp.

Blood vessels and nerves enter and exit from the apical foramen of teeth. When suffering from dental caries, bacteria corrode enamel and dentin and enter the pulp cavity, which is unbearable.

(See Figure 37) Students should do the following to protect their teeth: 1. Develop a good habit of brushing your teeth. Rinse your mouth with warm water after meals and brush your teeth once in the morning and evening.

Don't brush your teeth too often, it will damage your teeth, and don't brush your teeth for too long. Brush cheese? [ 14]? Returning to Mujiao M: Nuclear Spoon Rebellion Pan Ⅲ? ⑼ ⑼ ⑼ ⑼ ⑼ ⑼ ⑼ ⑼ ⑼ ⑼ ⑼ ⑼ ⑼ ⑼ ⑼ ⑼ ⑼ ⑼ ⑼ ⑼ ⑼ ⑼ ⑼ 2. Pay attention to oral hygiene and protect your teeth.

If there are cavities, they should be repaired or pulled out. It is not difficult to achieve the above points, the key is perseverance.

May all students have healthy and beautiful teeth. Good oral health care is not the only way to have healthy and beautiful teeth.

Eating habits also play an important role. Here are some suggestions to help you have a beautiful smile! Your teeth: the main symbol of health and beauty. Teeth enable us to enjoy all kinds of food! Healthy teeth can make us chew hard food, meat, raw food and fruit without scruple ... Good chewing can strengthen the strength of gums and promote saliva secretion. They participate in the digestive process and play a bactericidal role in teeth.

In addition to genetic factors, the color and hardness of our teeth also depend on dental care and eating habits. Keep your teeth healthy: a balanced diet! A balanced diet and proper dietary distribution throughout the day (in order to avoid snacks, four meals a day: breakfast, lunch, dinner and snacks) are very beneficial to strong teeth.

In fact, it helps our teeth to better resist * * *: enamel erosion, dental caries ... Fresh food, such as carrots, carrots or apples, rubs on the surface of teeth when chewing, which actually plays a role in cleaning teeth. In addition, lipids, some protein (casein of cheese), minerals (phosphorus, calcium, fluorine ...) and vitamin D have antibacterial effects, which limit the discharge of inorganic salts in enamel.

On the contrary, snacks, especially those "soft" foods, carbohydrate foods (candy or sweet drinks, bread, cakes, etc. ) or acidic foods (soda, fruit, juice) usually increase the risk of dental caries. Sugar can be converted into acid, which may destroy the enamel on the tooth surface.

If possible, clean your teeth carefully after every meal. If you don't have the conditions, you can also rinse your mouth seriously or chew a piece of sugar-free gum.

In fact, any increase in saliva flow will reduce the risk of dental caries. It should be pointed out that excessive drinking of coffee, tea and smoking may make teeth yellow.

Four dairy products make teeth stronger. They are the best sources of calcium and phosphorus we need, and the main minerals of tooth enamel and root supporting bone. Mineralization of deciduous teeth began in the fourth month of pregnancy, and mineralization of stone teeth began in the first year of birth.

After the teeth are formed, the enamel is renewed and maintained. We should drink milk, and it is better not to drink sweet drinks.

Dairy products (yogurt, etc. ) Also bring calcium, phosphorus and vitamin D, which will increase the absorption of calcium and phosphorus. Finally, the main protein casein in milk can limit the excessive discharge of inorganic salts in enamel.

People in the past did a good job: they usually ate cheese after dessert and reduced the acid secreted by carbohydrates with the help of casein and lipids in milk. Drink more mineral water, which is a natural source of fluorine. Natural mineral water meets the human body's demand for fluorine.

Fluorine can increase the enamel of teeth, strengthen teeth and protect teeth from microbial erosion. Most mineral water contains 0.3 mg of fluorine per liter, but some are as high as 8 mg per liter.

We can also see fluoride on the dining table. For pregnant women and children, there are also tablets made of fluorine (0.5 mg to 1 mg according to age).

Tea, sea fish and some vegetables (spinach, carrots, etc.) also contain fluorine. However, excessive intake of fluoride (more than 2 mg per day) may make teeth black.

Take advantage of chocolate and sugar-free chewing gum. In fact, cocoa contains tannic acid, fluorine and calcium phosphate. All three substances are involved in protecting teeth.

In "sugar-free" chewing gum, sucrose is replaced by sweet polyol, but it will not cause dental caries: xylitol plays a bactericidal role, which is beneficial to reducing dental plaque, and sorbitol (sugar synthesized from glucose or fructose, used as artificial sweet flavoring agent). So a 2.2g sugar-coated chewing gum has only 3.8 calories.

6. How do kindergartens do a good job in children's dental care?

For children who spend most of the day in kindergarten, oral health care in kindergarten plays a decisive role. I think kindergartens should do the following in dental care.

First, do a good morning check. When the child opens his mouth, the health care teacher can find many problems, such as whether to brush his teeth (check whether there is tartar on his teeth), whether to rinse his mouth after breakfast (check whether there is physical residue), and whether there is dental disease (small pus spots on the root caused by dental caries or chronic periapical periodontitis). ), and whether there are double-layered teeth (deciduous teeth have not fallen off, permanent teeth have erupted). If these problems occur, second, cultivate children to brush their teeth in the morning and evening and develop the good habit of gargling after each meal. Our garden requires young children to rinse their mouths with warm water at noon and after lunch every morning, which is divided into three parts: the first one is contained in the mouth, and the young children drum their cheeks left and right and giggle; Rinse your mouth with the second saliva and make a purring sound; The third saliva is the same as the first.

The teacher on duty makes a patrol inspection to ensure the quality of children's mouthwash after lunch. However, it is not enough just to rinse your mouth in kindergarten. We must cooperate with our families. First of all. Our garden publicizes the importance of protecting teeth and the correct method of brushing teeth to parents through the health publicity column, so that parents can set an example at home, so that children have the opportunity to imitate adults and improve their interest in brushing teeth.

Secondly, our garden combines health education classes to teach children some health knowledge, so that children can master the correct method of brushing their teeth and remind parents to supervise and inspect. Third, parents cooperate to correct their children's bad habits. Children's teeth are in the developing stage. Only by taking enough and balanced nutrition can they ensure their normal development.

For children with picky eaters and partial eclipse habits, we should not only correct them in kindergarten, but also let parents cooperate, change their children's diet patterns, mix them reasonably, let them eat foods containing calcium, phosphorus and vitamins, and chew some chewy foods containing crude fiber appropriately. Bad habits such as biting nails, sucking fingers, biting lips, breathing through the mouth, and unilateral chewing will cause children's teeth to be irregularly arranged. Teachers should contact parents to correct them in time.

Fourth, avoid children's teeth injury. Intense activity and noise can easily cause tooth damage. In normal times, teachers should not only strengthen safety education for children, but also take preventive measures seriously, pay attention to protecting children's teeth and avoid bumping.

5. Regular oral examination and caries prevention. Our garden carries out fluoride caries prevention treatment once a year and carries out oral examination for children once a year. If you find oral diseases, contact your parents in time and treat them as soon as possible to prevent them from developing. In addition, the pit and fissure of the six-year-old teeth of the big class are closed to prevent dental caries.

7. Tips for protecting teeth

Dental care. This is a very important part of beauty. Know your teeth.

Why yellowing or blackening is necessary to protect teeth.

When the teeth turn yellow, brown or black, we must first make clear the reason for tooth discoloration. Tooth discoloration can be divided into internal coloring and external coloring.

Two kinds.

Tooth internal coloring is tooth discoloration caused by the change of tooth tissue structure or nutrition. The common diseases are pulp necrosis, mottled enamel teeth and drugs.

Tooth discoloration caused by deposition, etc. Normal teeth are covered with a milky white, translucent and shiny substance when viewed from the longitudinal section.

Ze and particularly hard structural covering, it has the function of protecting teeth, because it looks like magnetic glaze, so it is called enamel. tooth

There is a yellowish thick dentin structure in enamel, which forms the main body of teeth. There is pulp in the center of the tooth, including blood vessels.

Nerves provide nutrition and metabolism for teeth. If the nutrition of the teeth changes or is cut off, the teeth will change color.

1. Tooth discoloration caused by pulp necrosis, such as pulp bleeding and necrosis caused by tooth trauma, teeth will turn dark red.

Brown or blue gray.

2. Mottled enamel teeth are commonly known as macular teeth. Before the age of 5, drinking water with fluorine content exceeding 65,438+0/65,438+0 million per 65,438+0 liter of water will make teeth.

The structure of enamel is poorly calcified and discolored. Light mottled enamel teeth with chalky or yellowish brown patches on the enamel surface; strict

The surface of heavy teeth is rough, uneven and yellowish brown, even black, and the teeth are fragile, so the treatment is more complicated. light-spot

Glazed dentists use dilute hydrochloric acid to smear macula to change color, which can make macula shallower, but attention should be paid to protecting gums and preventing decay when applying medicine.

Erosion and burns. Severe mottled enamel teeth can be repaired with "plastic tooth veneer" or "light-cured composite resin"

3. Drugs cause tooth discoloration. Mothers in the third trimester or children under 5 years old take tetracycline and oxytetracycline more.

Antibiotics combine with calcium to form yellow or gray tetracycline, and oxytetracycline antibiotics combine with calcium to form yellow or gray.

Colored tetracycline calcium complex is deposited in the structure of enamel and dentin through dental pulp, which makes the erupted teeth yellow.

Dark gray or dark brown. The preventive measure is to take tetracycline drugs as little as possible. At present, tetracycline drugs for children have been eliminated.

Medicine.

External coloring of teeth refers to pigmentation on the surface of teeth. For example, smoking, drinking, drinking tea, and pigments in the diet mixed with saliva.

After adhering to the surface of teeth, especially the occlusal surface of teeth, pigmentation is more likely to appear in the grooves and pits of lips and tongue.

At this point, the tooth surface turns brown, yellow, gray or blue-green. The tooth surface of people who have been exposed to iron and sulfur for a long time due to professional relations can be

Calm with brown elements. There may be melanin deposition on the surface of teeth exposed to mercury for a long time. Tooth surfaces exposed to copper, nickel and chromium for a long time will

There are green * * * elements.

Brushing your teeth in the morning and evening and gargling after meals can prevent the external coloring of your teeth. Dyed teeth can be wiped with a towel or cotton swab.

Wipe the tooth surface with 3% hydrogen peroxide. Seriously, use a doctor's rubber wheel to polish and remove the coloring.

8. Children's Teeth Teaching Plan

Health activities in large classes: holes in teeth (kindergarten teaching plan)

Activity goal: 1, knowing that acid will corrode teeth; 2. Can tell the hazards of more than three kinds of dental caries; 3. Watch cartoons, learn the five steps of dental prevention, and understand the correct common sense of dental care; 4. Cultivate children's good hygiene habits.

Activity preparation: 1, egg shell, biscuit, cup, vinegar, mirror 2. Soak the egg shell in vinegar with the children two days before class; 3. Pictures of dental caries process and five steps of tooth prevention. 4. Tooth model and toothbrush. 5. Comic book The Adventures of Prince Cong Cong's Tooth Prevention. 6. Some word cards.

Activity flow:

First, the rhythm comes into play, leading to situational performances; The deciduous teeth are crying. It turns out that his little master likes sweets and doesn't brush his teeth. After a long time, bacteria drilled several holes in the deciduous teeth.

Second, look for the cause of dental caries 1. Tooth baby invites children to eat biscuits, then gargles and observes what happens to the clear water. I know that people will leave food residue in their teeth after eating. Show picture 2. "There is a bacteria in our mouth that makes these food scraps sour (show pictures). If it takes a long time, what will happen to our healthy teeth? (Show pictures) 3. " There is an eggshell on the children's desk. What's it like to tap with chopsticks? (hard) What's in the cup? That's our eggshell dipped in vinegar two days ago. What about now? 4. Discussion: Why do eggshells turn black and soft? Vinegar is sour and will corrode the calcium in the eggshell, so the eggshell will turn black and soft. ) 5. Teacher's summary: There is a kind of bacteria in our mouth, which will make food residue sour. After a long time, these acids will corrode the calcium in our teeth like vinegar, and the teeth will turn black, resulting in tooth decay, which is dental caries. 3. What are the hazards of dental caries? Learn the five steps of tooth prevention and know the correct methods of tooth protection.

Fourth, the game "Protect your teeth with Jia Jia" (end) Method: Choose one child to play "Toothworm", one child to play "Jia Jia" and the rest children to play "teeth" after "Jia Jia". "Toothworm" will catch the teeth, and "tooth protection" will prevent "tooth worm" from protecting the teeth.
