walnut

Some people's teeth are hot, cold, sweet and sour, which will cause food soreness. This is called "tooth allergy". If you eat walnuts regularly, it can be improved. Walnut kernel is rich in fat oil, protein and other components, in which the fat and acidic substances can penetrate into the tubules of teeth for isolation, while protein, fat and calcium can also be treated by chemical changes. Walnut kernels can be eaten raw, or chewed repeatedly with the affected teeth after a little heating, 3 ~ 4 times a day.

2. Yali pear

Eating some fresh pears after meals, chewing slowly, washing teeth and massaging gums can eliminate food residue between teeth. It can also prevent and treat gingival hyperemia and atrophy caused by dental calculus, and improve blood circulation at the end of oral cavity, especially for gingival swelling and toothache caused by stomach fire and wind fire.

3. Rice, lentils, peas and broad beans

These foods are rich in phosphorus. Phosphate can form a buffer system to prevent excessive acidification of the mouth, so it has the effect of protecting teeth.

4. Marine fish, tea and mineral water

These foods contain fluorine. Fluorine can combine with hydroxyapatite in dentin to form fluoride-containing hydroxyapatite, which can enhance the resistance of decalcification of enamel, thus playing a role in preventing caries. In addition, fluoride can also inhibit the growth of bacteria by inhibiting enzymes in bacteria.

Chinese medicine believes: "The kidney governs the bone and produces marrow. Teeth are bones. " "Kidney failure means clear teeth, and kidney consolidation means strong teeth." Lycium barbarum has the function of nourishing liver and kidney. Long-term consumption can strengthen bones and muscles, so it can tonify kidney and strengthen teeth. Pharmacological research shows that Lycium barbarum can promote the proliferation and adhesion of periodontal ligament or fibroblasts.

6. Jujube

As the saying goes, "teeth benefit the spleen, dates benefit the spleen and lose teeth." Recently, it was reported abroad that Japanese researchers screened 74 kinds of traditional Chinese medicines in order to find out the traditional Chinese medicines to prevent tooth decay. Therefore, ursolic acid and oleanolic acid were extracted and separated from jujube. These two components can control the enzymes produced by dental caries without destroying the bacterial balance of oral bacteria.
