    The root cause of dental caries is not tooth worms, nor sugar, but several types of bacteria, mainly Streptococcus mutans. They are parasitic in our mouths, and are broken down by breaking down the glucose in the mouth to produce acids and at the same time produce acids. Under the action of acid, the teeth will dissolve and collapse a little, forming cavities. If we just don’t eat sugar, the food we eat will also be affected by saliva amylase to produce some glucose. These bacteria will still grow and damage the teeth. Therefore, to control tooth decay, in addition to not eating sugar, eat less sugar, but also maintain good oral hygiene and reduce the growth of bacteria.
