Bad breath is a very common problem and there are many different causes. Persistent bad breath is usually caused by the smelly gases released by the bacteria that coat your teeth and gums. However, strong foods like garlic and onions can add to the problem.
Smoking is also one of the main causes of bad breath, along with certain illnesses such as nasal and stomach conditions.
Correct and regular brushing is very important to keep your breath smelling fresh as bits of food can get caught between the teeth, and, if not cleaned away properly, can rot and cause an unpleasant smell.
The bacterial plaque on our teeth and gums also causes gum disease and dental decay. If you see your dentist regularly this will not only help prevent bad breath but will also allow the dentist to look for and treat these problems.
