  • Tooth decay is a diet-related disease. 
  • It is caused by the bacteria in your mouth converting sugar into energy and producing acid as a waste product.
  • Tooth decay can start as a white or dark spot on your tooth and develop into a hole.
  • The saliva in your mouth helps protect against tooth decay, and can repair tooth decay in its early stages.
  • If you have a dry mouth (for example due to dehydration, some medical conditions, or using certain medications or drugs) your risk of developing tooth decay is greater.
  • You can prevent tooth decay by eating a healthy diet, drinking plenty of tap water instead of sugary drinks, brushing your teeth twice a day using a fluoride toothpaste, and flossing.
  • Your dentist can treat tooth decay too. If you visit your dentist regularly (once or twice a year) you can discover tooth decay early before it needs a filling.
