Most people's concept of dental health care is correct and good brushing habits. Regular dental examination, in fact, should make more efforts in the choice of food and change the nature of teeth, which is the fundamental method.

If the body lacks calcium, the teeth will loosen and form dental caries. Vitamin D can promote the absorption of calcium and phosphorus, and vitamin A can also increase the antibacterial effect of gingival mucosa, so we should pay attention to ensuring the supply from the diet. In addition, fluoride is also very important to the health of teeth, and if it is lacking, it will easily lead to dental caries.

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, pears, etc., can play the role of mechanical scrubbing of 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 cleans the tooth surface through mechanical friction, stimulates salivary gland secretion, and reduces food adhesion and plaque formation. In addition, vegetable oil can form a hydrophobic layer on the surface of teeth to protect teeth and prevent dentin from dissolving.
