Hello, bad breath is generally related to oral hygiene habits, such as not brushing your teeth or gargling, often eating irritating food, or it may be caused by oral diseases such as dental caries. Periodontal diseases often make your gums in an inflammatory state, abscess bleeding, purulent purulent, and it is easy to produce a rotten stench. Some cases of indigestion may also lead to bad breath.
I suggest you pay attention to local hygiene habits, rinse your mouth and brush your teeth frequently, and you can also contain chewing gum. If you have physical diseases such as oral diseases or digestive dysfunction, it is best to go to the hospital for examination and treatment in time.
