Tips for dental care:

1, brush your teeth. Oral hygiene requires effective oral cleaning. First of all, you need to learn to brush your teeth and choose a toothbrush with a small and soft head.

2. Try to eat less sweets. Everyone knows that sweets can easily cause dental problems, destroy calcium around teeth and cause tooth decay, so we usually pay attention to eating less sweets.

3. Brush your teeth in the morning and evening. It is very important to protect teeth and maintain oral hygiene. Brush your teeth in the morning and evening and rinse your mouth after meals. In particular, you can't ignore brushing your teeth at night, because if you don't clean up the food residue in a day, you will find an unpleasant smell in your mouth overnight, which makes people feel uncomfortable from the morning.

4. Choose the right toothpaste. If dentin is allergic, use toothpaste suitable for sensitive teeth to help repair the damaged parts.

5. Drink less carbonated drinks. The acidity of carbonic acid will corrode the protective layer of teeth. If you drink too much carbonated drinks, it is not good for your health. Even if you drink too much carbonated drinks, try to choose drinks with less carbonated content, otherwise your teeth will loosen.

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 food residue, 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!
