Because 80%~ 90% of bad breath comes from the root of the tongue, dentists should teach patients to use the tongue curette correctly to clean the tongue surface. You can also find out the main pathogenic bacteria of patients through in vitro tests, and choose mouthwash that can effectively inhibit the growth of microorganisms on the tongue surface for local antibacterial.
Stimulate saliva secretion or use substitutes. Because saliva has antibacterial, bactericidal and oral cleaning effects, we should also consider increasing the amount and flow rate of saliva, enhancing tongue movement, chewing fiber-rich food or chewing gum. It is good for relieving bad breath.

cause of a disease
According to statistics, 80% ~ 90% of bad breath comes from the mouth. Untreated dental caries, residual roots, residual crowns, poor repair, abnormal anatomical structure, gingivitis, periodontitis, oral mucosal diseases and so on can all cause bad breath.
Dental caries and periodontal disease are the most common related diseases. Food residue and plaque often remain in the cavity of deep caries and under the overhang of bad restorations, and bacteria ferment and decompose to produce odor.
Pulp necrosis or suppurative pulpitis, without treatment, can also give off a bad smell; Periodontal patients are often accompanied by a large number of dental calculus and dental plaque, and bacteria in periodontal pockets ferment to produce hydrogen sulfide, indole and ammonia, thus producing odor.
In addition, periodontal abscess and periodontal pocket empyema are mostly caused by Staphylococcus aureus combined with periodontal pathogen infection, which also gives off an unpleasant smell. The quality and quantity of saliva also play an important role.
