The Parts of the Tooth

  • Enamel – The visible substance which covers the crown of the tooth is enamel. The enamel is the hardest substance in the body and guards the tooth rom decay. Calcium and phosphorus are the components that make up the enamel.
  • Dentin – Dentin is the layer underneath the enamel. The dentin is calcified and its appearance is very similar to that of the bone. Since the dentin is not as hard as the enamel, it is exposed to greater risk of decay that is if the enamel wears away.
  • Cementum – This is the layer that covers the root of the tooth and assists in anchoring it into the bone. This layer is even softer than the dentin and enamel; and is usually covered by the gums. The optimum way to safeguard this layer from decay is by taking care of your gums. Inadequate dental care can lead to gum disease and shrinking of gums which then exposes the Cementum to dangerous and destructive bacteria and plaque.
  • Pulp – At the center of your tooth you will find the pulp. It contains the nerves, blood vessels and other soft tissues which transport signals and nutrients to your tooth.
