Anatomy of a Tooth

Despite their small size, your teeth are actually very complex and constantly changing as you age.  All teeth, though different in shape, have the same anatomical parts. Each tooth has a crown – the part that is exposed to the oral cavity – and roots. The tooth is attached to the underlying alveolar bone with fibers known as the periodontal ligaments.

Each tooth is made up of the same components, including:

  • Tooth crown – This is the part of the tooth we see in the mouth.
  • Enamel –The hardest, semi-translucent outer part of the tooth. Enamel is mostly made of calcium phosphate, a rock-hard mineral.
  • Dentin – Dentin is the softer structure that comprises the majority of the tooth substance. It is full of tiny tubes that can transmit such signals as hot, cold, and painful stimuli to the pulp of the tooth where the nerves and blood vessels are found. It causes that yellow or blue/grayish color that we see in our teeth.
  • Pulp –The softer, living inner structure of teeth. Blood vessels and nerves run through the pulp of the teeth. It is often called the dental nerve. The nerves and blood vessels from the pulp are connected to the nervous and circulatory systems of the body.
  • Gums – Firm flesh around the roots of the teeth.
  • Root – Beneath the surface, embedded from the bone of the jaw, is the complex structure of the root of the tooth.
  • Cementum – A layer of connective tissue that binds the roots of the teeth firmly to the gums and jawbone.
  • Periodontal ligament – Tissue that helps hold the teeth tightly against the jaw.
  • Jawbone – The bone which forms the framework of the mouth and which holds the teeth.
