6 Possible Reasons Your Mouth Smells Even After Brushing Your Teeth

Have you ever brushed your teeth thoroughly, used mouthwash and still noticed an unpleasant smell coming from your mouth? This can be embarrassing, especially when speaking to someone at close range.

Many people assume that bad breath is always caused by poor brushing, but that is not necessarily true. Several conditions inside and outside the mouth can contribute to the problem.

1. Bacteria on your tongue Your tongue has a rough surface where bacteria and food particles can collect. Even when your teeth are clean, an unclean tongue may contribute to unpleasant breath. Gently cleaning your tongue with a tongue scraper or toothbrush can help.

2. Gum disease Gum infections can cause persistent bad breath. You may also notice bleeding while brushing, swollen gums, tenderness or loose teeth. A dentist can assess your gums and recommend appropriate treatment.

3. Tooth decay A cavity can trap food and bacteria, producing an unpleasant smell. Sometimes, tooth decay develops without severe pain at first. Regular dental examinations can help identify problems before they become more serious.

4. Dry mouth Saliva helps wash away food particles and bacteria. When your mouth becomes dry, unpleasant breath can become more noticeable. Dehydration, certain medicines, mouth breathing and some medical conditions can reduce saliva production.

5. Tonsil stones Small white or yellow deposits can sometimes form in the folds of the tonsils. These are known as tonsil stones. They may produce an unpleasant smell and sometimes cause a sensation that something is stuck in the throat.

6. Acid reflux and other health conditions Stomach acid moving back into the oesophagus can cause an unpleasant taste or smell in some people. Certain respiratory infections and other conditions may also contribute to bad breath. Persistent symptoms should be assessed rather than treated with mouthwash alone.

Final thoughts Brush twice daily with fluoride toothpaste, clean between your teeth, gently clean your tongue and drink enough water. If bad breath continues despite good oral hygiene, visit a dentist. The real cause may need treatment, and repeatedly masking the smell will not solve it.
