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. 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.
The bacteria on our teeth and gums (plaque) also cause gum disease and dental decay. 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.
To keep your breath fresh, you must keep your mouth clean and fresh. If you do have bad breath, try keeping a diary of all the foods you eat and list any medicines you are taking. Take this diary to your dentist who may be able to suggest ways to solve the problem.
Brush your teeth and gums twice a day with fluoride toothpaste. Don’t forget to brush your tongue as well. Use dental floss once a day for cleaning between your teeth. There are other products you can buy to clean between your teeth (they are called ‘interdental cleaners’).
