The different parts of a tooth consist of:
Enamel is the highly mineralized and hard outer substance of the tooth. Its colour varies from light yellow to greyish white.
Dentin is that part of the tooth which is present between enamel or cementum and pulp chamber. It is softer than enamel and therefore decays more rapidly.
Cementum is a bony substance covering the root of the tooth. Its colour is yellowish and is softer than dentin or enamel. The main function of cementum is to serve as a medium for periodontal ligament to attach to the tooth for stability.
The dental pulp is the centre portion of the tooth. It is filled with soft connective tissue which contains blood vessels and nerves .It is commonly called the “nerve of the tooth”.
