The most important thing that patients do not know is the basic anatomy of a tooth.

So here we start with the basics:

  • Enamel: It is an opaque or semi-transparent glossy substance that is a type of glass, applied by vitrification to metallic or other hard surfaces for ornament or as a protective coating
  • Dentin: It is a calcified tissue of the body, and along with enamel, cementum, and pulp is one of the four major components of the teeth
  • Pulp: It is the part in the center of a tooth made up of living connective tissue and cells called odontoblasts. The dental pulp is a part of the dentin–pulp complex (endodontium)
  • Crown: A tooth-shaped "cap" that is placed over a tooth in order to cover the tooth, restore its shape, size, strength and improve its appearance. The crowns, when cemented into place, fully encase the entire visible portion of a tooth that lies at and above the gum line
  • Root: Part of the tooth which is embeded in bone socket
