Why is the teeth loose, fall off? It is generally believed that “old teeth” is a natural phenomenon, in fact, this is wrong, the teeth will only be loose in the pathological state, fall off. Periodontal disease is the most common cause of tooth loss.

Caries often have no obvious symptoms in the early stages of caries, so people do not mind that caries often gets severe when severe and repeated pain occurs. Dental plaque, tartar, and calculus are the major causes of dental caries and periodontal disease. Dental plaque is a group of microorganisms that adhere to the surface of teeth. It consists of a large number of microorganisms, intercellular substances, a small amount of white blood cells, shedding of epithelial cells
