Tooth Anatomy

We believe that the more our patients understand their teeth, the better equipped you are to care for your teeth. So here’s a quick guide to the three areas of your teeth: the crown, neck, and root.

  1. The crown is the surface or the part of the tooth that you can visibly see. As stated in our previous blog, different types of teeth have different functions. Therefore, the tooth crowns differ in appearance.
  2. Did you know that the enamelis the most mineralized and hardest tissue in your body?  Mainly made of calcium phosphate, enamel coats the crown of the tooth. Enamel’s primary purpose is to keep your teeth healthy and protect them from decay. Maintain a healthy diet and avoid foods that contain too much sugar and acid to help your enamel!
  3. Digging deeper, inside the strong enamel of your tooth lies a layer called dentin or dentine. Dentin is harder than bone and is comprised of calcium and phosphate apatite crystals. Dentin is also filled with canals called dentinal tubules.
  4. The layer below the dentine is the soft tooth center called the pulp. All the tooth’s nerves, blood tissues, and lymph vessels are found here. The job of the nerves and blood tissues is keep the tooth nourished. The pulp is also sensory; this is how you feel hot and cold sensations.
  5. The neck (gumline) visually divides the crown of your tooth from your gums. If neglected, certain types of gum diseases such as gingivitis, can develop. Make sure to brush your teeth and floss daily!
  6. Lastly, the root of the tooth lines beneath the neck or gumline. It is approximately two thirds of your entire tooth. The root’s main job is to hold the tooth to the jawbone. The root is covered by the cementum, a hard bone-like tissue. The cementum is linked to the tooth’s socket by a periodontal ligament. Here’s a fun fact: a person may have one or more tooth roots!
