First, identify the specific causes of bad breath. For example, eating certain foods, such as onions and garlic, can cause halitosis. In terms of diet, oral hygiene can be improved. There are also halitosis caused by oral diseases, such as dental caries, gingivitis, poor restorations, periodontal diseases, oral mucosal diseases, etc., which can cause halitosis. The corresponding treatment measures should be taken according to the specific causes in the dental department, and oral hygiene should also be done well. Another reason is that due to inflammatory diseases of oral adjacent tissues, such as suppurative tonsillitis, chronic sinusitis, etc., appropriate antibiotics should be used for treatment. The other is caused by Helicobacter pylori infection, which can be treated with double antibiotics. A course of treatment is two weeks.
