Tooth decay occurs when a hole (cavity) forms in your tooth. It can affect people of all ages and even very young children. Having tooth decay can affect your health and lead to other conditions. However, tooth decay can be prevented or treated.

Tooth decay is caused by plaque — a sticky layer of germs — in your mouth. The germs in plaque turn the sugar in food and drinks into acid, which can gradually damage your teeth.

Tooth decay can be prevented by practising good dental care. This includes:

• having sweet foods and sugary drinks only occasionally and, if possible, only at mealtimes

• brushing your teeth twice a day with a fluoride toothpaste

• limiting or avoiding sugary snacks

• having regular dental check-ups — many dental health experts recommend an appointment every 6 months

Because you can have tooth decay without any symptoms, you should visit your dentist regularly since they will check for tooth decay.

See your dentist as soon as possible if you have a toothache, tooth sensitivity (eg to hot or cold food or drinks), brown, black or white stains on your tooth surface and pain on biting. Book your appointment now or call us at 02 8383 1400.
