  • Tooth decay is a common diet-related disease.
  • It is caused by the bacteria in your mouth turning sugar into energy and producing acid that damages the teeth.
  • Tooth decay can start as a white or dark spot on your tooth and develop into a hole or cavity.
  • The saliva in your mouth helps protect against tooth decay and can repair tooth decay in its early stages.
  • If you have less saliva or a dry mouth (because of dehydration, some medical conditions, or using certain medications or drugs) your risk of developing tooth decay is higher.
  • You can prevent tooth decay by eating a healthy diet, avoiding sugar sweetened drinks, drinking plenty of tap water, brushing your teeth twice a day using a fluoride toothpaste, and flossing once a day.
  • Regular professional care can help to identify and prevent decay and may avoid the need for a filling.
