Main Causes of Cavities

April 29, 2022

Cavities are not just painful but also one of the biggest reasons why a dentist needs to perform root canal treatment and extractions. 

The formation of cavities can largely be avoided by following a proper dental health regimen which means brushing and flossing the teeth properly — and visiting the dentist on a regular basis. 

Proper brushing and flossing are key in avoiding cavities, as failure to do so begins a three-part process:

  • Food debris, acids and bacteria start to build up in the mouth and on the teeth and gums.
  • The excess plaque, harmful bacteria and acids start to erode tooth enamel and weaken teeth.
  • Bacteria penetrates into the tooth, destroys the inner tooth pulp and a cavity begins to form.

In the early stages a cavity is usually typified by a small stain on a tooth with possible accompanying tooth sensitivity. 

At this stage, the cavity may be able to be reversed by a dentist with a thorough cleaning and possibly fluoride treatment. 

Without swift and proper treatment, however, the entire tooth may decay and necessitate root canal treatment or even a complete extraction to remedy the problem. Read more on this topic at
