How does tooth decay happen?
These bacteria need to feed on the sugars in the food and drink that we consume in order to make the acid. Once all the sugar has been used up, the acid gradually disappears and the tooth has a chance to repair itself. The minerals in saliva help this to happen.
If plaque is not removed regularly, or if sugar is eaten too often, then plaque bacteria can keep producing more and more acid, and the tooth doesn’t get a chance to repair itself properly. Eventually a small hole (or cavity) appears.

What can happen next?
Eventually, when the hole gets large enough, the pulp becomes damaged and can die. Bacteria from the mouth can then infect the dead pulp and cause an abscess and toothache.
