There are no worms in the worm's teeth. Worm teeth are not caused by insects, but by bacteria.

According to the research of modern dental caries, dental caries is caused by four interrelated factors, including bacteria, food, host and time. There are countless bacteria in the mouth, some of which can utilize and decompose carbohydrates in food, and then produce acid. These acids accumulate and adhere to the surface of teeth for a long time, resulting in the dissolution of inorganic components in teeth. After a certain period of time, a hole visible to the naked eye is corroded on the surface of the tooth, and a "worm tooth" is formed.

Extended information:

The following four factors are indispensable for caries to occur.

1. Bacteria

Bacteria are the most important factor of dental caries. Without bacteria, there would be no dental caries. Studies have proved that once teeth erupt, dental caries may occur in contact with bacteria in the mouth.

2. Food

Food is an important material basis of bacterial caries, and sucrose contained in it is an important factor causing dental caries. The cariogenic ability of sugar is closely related to the type of sugar, the viscosity of sugar, the time and frequency of eating sugar, etc., while eating rough and fibrous food has a certain self-cleaning and anti-caries effect.

3. Host

Everyone's resistance to dental caries is different, which involves many factors, such as the composition of saliva, the amount of saliva, the shape, structure and arrangement of teeth, and the general health status. Specifically, saliva can clean teeth, and some components in saliva can inhibit the generation of dental caries and periodontal disease. Therefore, patients with less saliva secretion and easy to dry mouth are prone to dental caries < P >; Dental caries is also easy to occur in irregular, crowded and overlapping teeth. In addition, heredity, nutrition, mineral intake, endocrine and other factors also have a certain impact on individual anti-caries ability.

4. Time

The occurrence of dental caries is not a short process. It usually takes about 1.5~2 years from the time when bacteria attach to the tooth surface to the time when dental cavities are visible to the naked eye. That is to say, even if bacteria, host and suitable environment coexist, dental caries will not form in a short time.
