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.
Bits of food that get caught between the teeth and on the tongue will rot and can sometimes cause an unpleasant smell. So correct and regular brushing is very important to keep your breath smelling fresh.
However,strong foods like garlic, coffee and onions can add to the problem. The bacteria on our teeth and gums (plaque) also cause gum disease and dental decay. One of the warning signs of gum disease is that you always have bad breath or a bad taste in your mouth. Again, your dentist or hygienist will be able to see and treat the problem during your regular check-ups. The earlier the problems are found, the more effective the treatment will be.
