Bad breath is a very common problem that can affect anyone of any age and there are many different causes.
Persistent bad breath is often caused by the smelly gases released by the bacteria that coat your teeth and gums. However, eating strongly flavoured foods, such as onions and garlic, can cause your breath to smell unpleasant. Smoking and drinking can also cause bad breath.
Good oral hygiene is usually enough to prevent and treat bad breath. Brushing your teeth at least twice a day and cleaning between your teeth is very important to keep your breath smelling fresh.
If you see your dentist regularly this will not only help prevent bad breath but will also let the dentist look for and treat these problems.
