Preventing Toothache

The best way to avoid getting toothache and other dental problems is to keep your teeth and gums as healthy as possible. To do this, you should:

Limit your intake of sugary foods and drinks – you should have these as an occasional treat and only at mealtimes
Brush your teeth twice a day using a toothpaste that contains fluoride – gently brush your gums and tongue as well
Clean between your teeth using dental floss and, if necessary, use a mouthwash
Don’t smoke – it can make some dental problems worse

Make sure you have regular dental check-ups, preferably with the same dentist.

The time between check-ups can vary, depending on how healthy your teeth and gums are and your risk of developing future problems.

Your dentist will suggest when you should have your next check-up based on your overall oral health.

Children should have a dental check-up every six months so tooth decay can be spotted and treated early.
