1, the dietary principle of protecting teeth
1, limit the intake of sweets.
Eating too much sweets is an important factor in the high incidence of dental caries in children, so it is necessary to limit sweets in children's diet. A few minutes after eating sugar, children should drink some boiled water or rinse their mouths with water. If you are a baby, avoid sleeping with nipples. Because the saliva secretion and swallowing action are greatly reduced after the child falls asleep, the milk trapped in the mouth provides sufficient nutrition for the reproduction of corrosive bacteria and promotes the formation of dental caries.
Step 2 supplement adequate nutrition
Let children eat foods rich in protein, calcium, phosphorus, vitamins A and D, which can promote the development and firmness of teeth. On the contrary, the supply of nutrients is insufficient, and children not only delay teething, but also the teeth that have already grown are easily corroded by bacteria and have dental caries.
3. Eat some foods containing fluorine.
Fluorine is an indispensable substance to keep teeth healthy. It exists in enamel in the form of calcium fluoride and fluorapatite, which has the functions of acid resistance and caries prevention. Fluorine-containing foods include kelp and shrimp. And the fluorine content in tea is also relatively high. You can also choose fluoride toothpaste to brush your teeth.
4. Eat some foods rich in fiber.
You can deliberately give your child some vegetables and fruits that are rough or contain more cellulose. When these foods are chewed in the mouth, they have obvious friction and cleaning effects, which can not only stimulate tooth growth, but also strengthen periodontal tissue structure, thus reducing and preventing dental caries.
Special reminder:
Besides keeping good eating habits, we should also pay attention to oral hygiene. 1.5 years old children can be taught to brush their teeth or rinse their mouths with warm water after eating or before going to bed. Children aged 2 ~ 3 should develop the habit of brushing their teeth after 20 deciduous teeth are out. Don't eat snacks after brushing your teeth at night and before going to bed. Infants and young children can be scrubbed by parents with clean gauze or cotton swabs. In addition, once the child's deciduous teeth are found to have cavities, they should be treated in time.
2. Methods of daily dental care
1, choose the right toothbrush and brush your teeth correctly.
When brushing teeth with a bristle toothbrush, the protective effect of enamel (which leads to dentin hypersensitivity and tooth decay) fails, and the gums deteriorate due to excessive pressure on the teeth. On the contrary, using a soft toothbrush can protect the enamel well. It is recommended to clean teeth by circular scrubbing every day, and the best time is two minutes. Therefore, when buying a toothbrush, you must read it carefully before buying it.
2. Floss your teeth frequently.
Bacteria remaining in the crevices of teeth, after a long period of accumulation, are easy to form plaques, which is the chief culprit leading to tooth decay and periodontal disease. It is recommended to floss at least once a day to help remove dental plaque hidden between teeth. Girls can put a piece of dental floss or other toiletries in the cosmetic bag, which is convenient for cleaning anytime and anywhere and caring for dental health.
3. Eat less hard food
Nowadays, many people like to eat hard food, such as ice, hard candy, walnuts and so on. Because it's delicious and chewy. In fact, eating some hard food in moderation is very beneficial to dental care. The effect of dental care can be achieved by continuous chewing, but if it is excessive, it is easy to cause gum rupture and bring harm to teeth.
Step 4 use the right toothpaste
Now there are all kinds of toothpaste on the market, including calcium toothpaste and fluoride toothpaste. But in fact, fluoride is the most important thing to protect teeth. Those so-called toothpastes containing other nutrients are not only harmful to dental health, but also corrode enamel and lead to gum degeneration when used improperly.
Step 5 avoid food staining
The enamel in teeth is like a sponge, which can easily absorb the pigments entrained in various foods, such as coffee, cola and red wine. If you don't clean your teeth in time after eating, it's easy to accumulate pigments. After a period of time, it will adhere to the tooth surface, making the tooth look dull and dark yellow.
