Insufficient calcium intake will shake the bones, in fact, it will also wear away the health of teeth, so calcium should be supplemented from various natural foods every day. Cheese is not only a good source of calcium, but also has other protective effects on teeth. British research pointed out that 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; Moreover, regular consumption of cheese can increase the calcium on the surface of teeth, which helps to strengthen and rebuild enamel (because calcium is the most important component of enamel) and make teeth stronger. Have a tomato and cheese sandwich for breakfast. Prepare 2 slices of whole wheat toast, 1 slice of tomatoes about 3 cm thick, 1 slice of low-fat cheese. Put the cheese slices on the toast first, and then put the dried tomatoes; According to personal taste, squeeze a little yellow mustard sauce and sprinkle a little black pepper; Then clip the materials together with another piece of toast.

Now because of drinking green tea, even my teeth are healthier. On the one hand, green tea contains a lot of fluorine (as do other teas), 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. How to eat depends on personal preference. Drink 2 ~ 5 cups of green tea every day. It is recommended to drink after meals or desserts. In addition, green tea contains caffeine, so pregnant women should limit their drinking. Four: Onion: It can kill many kinds of bacteria, including Streptococcus mutans, which causes our tooth decay.

It is suggested to eat half a raw onion every day, which can not only prevent tooth decay, but also help to lower cholesterol, prevent heart disease and enhance immunity. When making lettuce salad, you can peel some fresh onions and add them; Or put some chopped raw onions in hamburgers and sandwiches. Five: Lentinus edodes: Lentinus edodes polysaccharide can inhibit oral bacteria from producing dental plaque. Mushrooms have not only become a popular food to enhance immunity in recent years, but also been found by some studies to help protect teeth since 2000. The reason is that lentinan contained in shiitake mushrooms can inhibit the bacteria in the mouth from producing dental plaque. Mushrooms are unique in taste and low in calories.

Six: Sugar-free chewing gum: Chewing can increase saliva secretion, neutralize the acidity in the mouth, and further prevent tooth decay. Seven: Honey: Honey contains an enzyme that can inhibit bacterial activities that damage teeth and cause dental caries. Eight: Natural mineral water: it is a natural source of fluorine, which can increase the enamel of teeth and strengthen teeth. Nine: mint: relieve the discomfort of inflammation and swelling of gums. 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. After eating a big fish and meat, drinking a cup of mint tea without sugar can relieve boredom and relieve bloating; If you are worried about the pungent smell of onions and garlic, it is recommended to chew 2 ~ 3 pieces of fresh mint leaves or parsley to help remove these embarrassing smells. Ten: Mustard: When tasting sashimi or sushi in Japanese cuisine, there should be mustard that makes people cry and have a runny nose, mainly for sterilization. Mustard produces such a pungent and suffocating smell because it contains an ingredient called isothiocyanate, which is also found in other cruciferous vegetables. Experiments in test tubes in Japan found that this substance in mustard can inhibit the reproduction of Streptococcus mutans, leading to tooth decay.
