when the acidity in the mouth is strong enough to reach the pH value Five point five The enamel of teeth will gradually dissolve, leading to the loss of minerals But if the pH value rises after the acidity is diluted by saliva, the dissolved tooth surface will start to absorb the calcium and phosphorus in saliva and return to enamel, which is called recalcification
cheese, which is good for the growth of children’s teeth or for the healthy and fixed teeth of adults.
secondly, Lentinus edodes also contain vitamin D source (ergosterol) which is lacking in common vegetables. Ergosterol can be transformed into vitamin D by sunlight, which can enhance the immune ability of human body and help children’s bones and teeth to grow.
Every 100g of dried mushroom contains Seven point eight Gram of crude fiber is just like a “toothbrush”. When chewing, mechanical friction occurs with the tooth surface, which can clean the teeth and reduce the formation of plaque
also has the function of killing harmful bacteria and protecting teeth.
can stimulate the secretion of saliva by chewing crude fiber food repeatedly, so as to balance the pH in the mouth.
not only that, raisins can promote stomach and promote body fluid, which can protect teeth.
as for the sour and sweet taste of raisins, it comes from fructose and glucose, rather than sucrose, which is harmful to tooth health.
So snack lovers can munch on raisins without worrying about their teeth
Other carbohydrates, such as starch, are also broken down into sugars by starch enzymes in saliva. They can also be fermented by bacteria to produce organic acids, but it will take a long time
and saliva contains calcium and phosphorus, which can promote the calcification of the decalcified tooth surface again, which can help to avoid tooth decay.
There are also some immunoglobulins in saliva, which can resist bacteria and protect the oral mucosa and teeth. The food that
stimulates saliva secretion should be put at the end of each meal. The best example is cheese, which not only stimulates saliva secretion, but also the high protein component can be acid in the mouth, and the high calcium and phosphorus component can also promote recalcification
high fiber food can reduce tooth decay, especially lettuce, because it will not stick to the teeth, and it needs to chew harder, stimulating the secretion of more saliva.
So if you can’t brush your teeth immediately after meals, you can put this kind of food at the end of each meal, or drink water to clean your mouth Hard food needs to be chewed more forcefully and many times. It can promote the blood circulation of tooth flesh, strengthen periodontal ligament, help bone resorption of bone groove and the formation of new bone, prevent periodontal glass and stimulate a large amount of saliva secretion at the same time, which is good for oral health care
when the acidity in the mouth is strong enough to reach the pH value Five point five The enamel of teeth will gradually dissolve, leading to the loss of minerals But if the pH value rises after the acidity is diluted by saliva, the dissolved tooth surface will start to absorb the calcium and phosphorus in saliva and return to enamel, which is called recalcification. The presence of
fluoride can promote the occurrence of recalcification and slow down the progress of tooth decay, and even can make the tooth decay which has not yet broken the hole at the initial stage and restore its original healthy appearance In addition, low concentration of fluorine can inhibit the acid production ability of bacteria; medium concentration of fluorine can inhibit the growth and metabolism of bacteria; high concentration of fluorine has bactericidal effect Fluorine content in food is very small. At present, adding fluorine 1ppm in tap water artificially, although the fluorine content is low and there is no bactericidal effect, it can reduce the acid production capacity of bacteria and reduce 65% of cases of tooth decay.
but if the concentration is too high, it will have a reaction, making the teeth appear brown spots, which can never be removed, which is very ugly
in addition, long-term consumption of vitamin C chewable tablets can also cause enamel damage;
