Anatomy of a Tooth

The tooth is made up of many layers and parts that keep it strong and healthy. Learning about the many parts of the tooth helps you understand what we use them for and how you can keep them healthy.

The Different Parts of a Tooth

The outer part of the tooth is the enamel. It is the hard, white material that protects the inner components of the tooth. Enamel is made of mostly calcium phosphate.

Underneath the enamel is dentin, a hard but porous or tubular material. If the enamel is damaged, heat or cold enters the inner parts of the tooth through these tubes and causes sensitivity or pain.

Inside the tooth is the dental pulp, which keeps the tooth alive. The tissue is made up of blood vessels and nerves.

Other types of tissue that connect the tooth to the jaw are cementum and periodontal ligaments. Cementum is a layer of connective tissue that keeps the roots bound to the gums and jaw bone. Periodontal ligaments also hold teeth against the jaw. The socket of the tooth uses these tissues to keep teeth in place, and if a tooth is lost it closes up, jawbone density may be lost in the process.

Types of Teeth

People have five types of teeth in the smile. The wisdom teeth are located in the far back of the smile, also known as third molars. Typically, adults have four third molars that erupt around the ages of 18-23. However, some patients may have less than four.

Individuals have eight Premolars, which are found between the canines and the molars. These are predominantly used for chewing and grinding food, similar to the molars.

Incisors are the four middlemost teeth in the upper and lower jaws. People have eight incisors, and they make up the most visible teeth in the smile. They are also used to speak and bite food.

Canines, which people have four in total, are the pointed teeth next to the incisors. These are sharp teeth that allow people cut and chop food while masticating.

Lastly, the molars, which you have eight of, are the flat teeth at the back of the mouth. They are best known for grinding food.
