Bad breath can be the result of numerous things, but it’s usually caused by poor oral hygiene. If bacteria builds up in your mouth, it can cause your breath to smell. Bacteria break down pieces of food in the mouth, releasing unpleasant-smelling gas. Any food trapped in your teeth will be broken down by bacteria, causing bad breath.
Professional cleaning by the dentist can reduce bad breath caused by periodontal diseases. If bad breath is caused by other health problems, then it should be checked out as soon as possible and the required treatment should be done.
