There are a few different causes of bad breath. It ranges from stomach problems to diets and teeth problems. Most of the causes can be found in the mouth, they are:

1- Tongue (when bacteria grows in between the papilla) 2- Teeth cavities (especially when food particles get stuck in them) 3- Gum diseases 4- Extraction sites during healing 5- Dentures when not cleaned properly 6-Alcohol and tobacco

If you or someone you know is concerned about bad breath, the first step is a dental check-up. Your dentist will be able to confirm or rule out teeth or mouth as the source of bad breath.

When the reason is found, treatment will be explained by your dentist. If the source of the bad breath is your mouth there is little chance that mouthwashes or mints can treat the problem. They usually mask the problem for a short period of time. They can even sometimes make the situation worse (mouthwashes that contain alcohol cause dry mouth and that usually makes the bad breath worse).

These are a few other, non-dental reasons that cause bad breath:

1- Sore throat 2- Tonsillitis 3- Some foods 4- Infection of air passages.

Following a good oral hygiene routine and getting regular check-ups with your dentist are the best ways of preventing bad breath.
