Not all bad breath can be treated in the same way. Generally speaking, bad breath can be divided into three types: oral, non-oral and physiological. You need to know what kind of bad breath you belong to and then prescribe the right medicine.
If there are oral diseases, such as periodontitis, oral mucosal diseases, partial oral necrosis, tooth decay and so on. It belongs to oral halitosis.
If your mouth is healthy, but you suffer from respiratory purulent diseases such as rhinitis and tonsillitis, and respiratory odor caused by diseases such as digestive tract diseases, it belongs to non-oral halitosis.
If it is bad breath caused by food hygiene, that is, bad breath caused by not cleaning in time, it belongs to physiological bad breath.
I can't give you further advice because I don't know what kind of situation you belong to. The following are for reference only:
1. Physical examination to determine the cause.
2. Appropriate vitamin B and E supplements. Of course, if you are very nutritious, you don't have to.
3. Rinse your mouth frequently and develop good hygiene habits. Brush your teeth at least twice a day, and it is best to clean your mouth after meals. If you have braces, you should pay more attention to cleaning. Use a toothbrush or professional sanitary ware that can clean the tongue coating, and rinse your mouth with mouthwash containing various mineral components to keep your mouth clean and microbial balance.
4. Chew gum and other sweets that can stimulate saliva secretion to maintain oral activities; Eat less spicy and greasy food.
