Dental caries, or cavities, as we commonly call them, are caused by a breakdown of tooth enamel, which is the result of bacteria on the teeth that breakdown sugars and produce acid that's destructive to tooth enamel. But what are the different types of cavities?
When you see your dentist for a check-up, they will use instruments to help detect soft spots on your teeth visible to the eye. Your dentist may also need current X-rays (or take new X-rays) to detect cavities.
Depending on its extent, decay is classified as incipient, moderate, advanced or severe. But to understand these categories, it helps to know a bit about tooth anatomy. The outer layer of a tooth is made up of calcified enamel that protects the inner portion of the tooth called dentin. At the centre of the tooth is the pulp chamber, which is the innermost layer that consists of nerves, blood vessels, and connective tissue.
Using the system outlined above, dentists evaluate tooth decay based on how far the damage has penetrated these layers of tissue:
Early detection and treatment of decay with fillings can prevent more serious complications or tooth loss in the future.
