What are the layers inside a tooth?
The layers of a tooth are:
Enamel – The outer layer that protects your teeth from being damaged by things like hot and cold foods and drinks. This layer can’t be restored once it’s damaged, so you want to make sure you protect it by brushing and flossing regularly.
Dentin – The middle layer of your tooth that contains nerves, blood vessels, and connective tissue. Dentin also makes up most of the structure of your tooth.
Pulp – The innermost part of the tooth that contains nerves, blood vessels, connective tissue, and pulp tissue (also called dentin).
