Tooth Anatomy

Tooth Anatomy is comprised of several different structures. Each structure plays an important role in the overall functioning of the tooth. The enamel is the outermost layer of the tooth and is composed of a hard, shiny substance called dentin. It is the hardest substance in the body and provides protection to the inner structures of the tooth. It also helps to keep bacteria and other substances from entering the tooth. The dentin lies underneath the enamel and is a softer substance than the enamel. It is made up of tubules filled with a fluid that helps to protect the inner structures of the tooth. It also helps to transmit sensation from the tooth to the nerves in the jawbone.
