What is the "tooth worm" among the folk "tooth worms"?

Dental caries, commonly known as tooth decay and dental caries, is a bacterial disease, which can lead to pulpitis, periapical periodontitis and even alveolar bone and jaw inflammation. If it is not treated in time, the lesion will continue to develop and form cavities, and finally the crown will be completely destroyed and disappear, and the final result of its development is tooth loss.

At present, the accepted theory of caries etiology is a four-factor theory, which mainly includes bacteria, oral environment, host (that is, parasites include parasites, viruses and other organisms parasitic on them) and time. Its basic point is that cariogenic food sugars (especially sucrose and refined carbohydrates) are closely attached to the tooth surface, and the acquired membrane is formed by saliva protein.

This kind of acquired film can not only firmly adhere to the tooth surface, but also have enough time to produce acid in the deep layer of dental plaque at a suitable temperature. The acid will attack the tooth, demineralize the tooth, and then destroy the organic matter and produce tooth cavities.
