Bad breath may persist in some people despite regular brushing, which may indicate causes that go beyond daily oral care habits and require searching for the underlying problem.
Common causes include gingivitis and the accumulation of bacteria on the surface of the tongue and between the teeth, as these bacteria produce compounds with unpleasant odors. Dry mouth may also contribute to worsening the problem due to reduced saliva secretion, which helps clean the mouth and limit bacterial accumulation.
Potential causes are not limited to dental and gum problems, but may also be linked to tonsillitis or gastroesophageal reflux, which may lead to stomach contents rising into the esophagus and contribute to the appearance of an unpleasant odor in some people.
The British National Health Service (NHS) recommends seeing a dentist if bad breath persists for several weeks despite adhering to home care, especially if accompanied by symptoms such as bleeding or swollen gums or tooth pain.
Proper care begins with gently brushing teeth and gums twice a day for two minutes using fluoride toothpaste, while cleaning the spaces between teeth daily with floss or specialized brushes.
It is also recommended to clean the tongue gently and drink enough water to reduce dry mouth. If the odor persists despite following these steps, it is important to see a dentist to identify and treat the cause rather than just relying on toothpaste or mouthwash.
