Whether the teeth are neat and white has a lot to do with a person's appearance and temperament. Whenever we want to describe handsome men and beautiful women, we often use these words to describe them, such as: white teeth, red lips, bright eyes and white teeth, etc., which are inseparable from describing their teeth. Therefore, at present, the new and new human beings have armed their teeth with bodybuilding actions and put shiny braces or beautiful crystal ornaments on their teeth, but the most important thing is to have white and bright teeth. It is of course very important to eat some foods that are beneficial to tooth whitening and health.

First, celery: When you chew raw celery, it is helping your teeth to have a comprehensive cleaning, so that you can reduce the chance of tooth decay. Because this kind of coarse fiber food is like a broom, it can sweep away some food residues from teeth. Moreover, the harder you chew, the more you can stimulate saliva secretion, balance the pH value in the mouth, and achieve the natural antibacterial effect.

Second, guava: Guava is low in calories. Many people use it to increase satiety when dieting, and its vitamin C content is the highest among fruits. Vitamin C is an important nutrient to maintain healthy gums. People who are seriously deficient will become fragile, prone to illness, and have symptoms such as swollen gums, bleeding, loose teeth or falling off.

Third, cheese: Everyone knows that insufficient calcium intake will shake the bones, in fact, it will also wear the health of teeth, so we should supplement calcium from various natural foods every day. Moreover, the calcium and phosphate contained in cheese 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 of cheese can also increase the calcium on the surface of teeth, which helps to strengthen and rebuild enamel and make teeth stronger.

Fourth, green tea: green tea contains a lot of fluorine, which can combine with apatite in teeth and has the functions of acid resistance and tooth decay prevention. On the other hand, studies have shown that catechins in green tea can reduce Streptococcus mutans, which causes oral cavity decay, and can also remove unpleasant breath.

5. Onion: The sulfur-containing compound in onion is a powerful antibacterial component. In the test tube experiment, it was found that onion can kill many kinds of bacteria, including Streptococcus mutans, which causes tooth decay, and fresh raw onion has the best effect.

6. Lentinus edodes: In recent years, Lentinus edodes has not only become a popular food to enhance immunity, but some studies since 2000 have also found that Lentinus edodes is also helpful to protect teeth. The reason is that lentinan contained in shiitake mushrooms can inhibit the bacteria in the mouth from producing dental plaque.

Mustard: It contains an ingredient called isothiocyanate, which is also found in other cruciferous vegetables. It can inhibit the reproduction of Streptococcus mutans which causes tooth decay.

Eight, mint: the faint fragrance of mint helps to refresh the mind and reduce "bad breath." Peppermint leaves contain a monoterpene compound, which can reach the lungs through blood circulation, making you feel fresh when breathing. In Europe and America, many families use mint leaves to make mouthwash to relieve the discomfort of swollen gums. Foreign research also found that the use of this herbal mouthwash can reduce the growth of bacteria in the mouth.
