2, bananas: tropical fruits contain high vitamin C, which can maintain healthy gums.
3. Cheese: Calcium and phosphate can balance the pH value in the mouth and prevent the mouth from being in an acidic environment conducive to bacterial activities, leading to tooth decay. Regular consumption can increase calcium on the surface of teeth, help strengthen and rebuild enamel, and make teeth stronger.
4, mint: mint leaves contain monoterpenoids, which can make the breath fresh. Green tea, onions and mushrooms are all good for protecting teeth.
5. Kiwi: The vitamin C content of Kiwi is among the best among fruits, and it is the guardian of gums.
6, water: moderate drinking water can keep the gums moist and stimulate saliva secretion. Drink water after eating, and take away the food residue in the residual mouth, so as not to let the bacteria get nutrition, take the opportunity to make trouble and damage the teeth.

Precautions:
1, you don't need to brush your teeth immediately after drinking soda: brushing your teeth frequently can certainly remove food residues and reduce the chance of tooth decay, but acidic drinks or foods such as soda and cola are exceptions. Acidic substances combined with brushing will wear away enamel.
2, use mouthwash instead of toothbrush: mouthwash can not remove plaque, nor can it prevent periodontal disease, so it can not replace brushing.
3. dentine hypersensitivity is because the dentin under the enamel (also called ivory) is exposed. Dentin is embedded with many tiny tubules. Contact with cold, hot, sweet and sour food, or inhalation and brushing teeth will make the liquid in the tubule flow and stimulate the pulp nerve.
4. Teeth have the ability of self-repair. The minerals in saliva react with the liquid in the dental tubule to form sediment, which can naturally seal the dental tubule and gradually relieve the pain.
