The cause of dental caries is not the bugs, but the bacteria in the mouth, so there is no practice of smoking the bugs out of the teeth, and dental caries is recommended to be filled as early as possible. Dental caries is mainly caused by a combination of factors such as plaque, time, oral environment and host, among which plaque is the initiating factor of dental caries, and the decayed tissues contain a large number of bacteria and their metabolites, therefore, the root cause of dental caries is to remove the decayed tissues and then fill the treatment. In addition, it is recommended that caries be detected and treated as early as possible, otherwise caries will cause pulpitis and periapical periodontitis, which will delay the condition and also increase the difficulty and cost of treatment. It is recommended to go to a regular hospital stomatology department for regular checkups.
