The dentist can be scary, but it can be a little bit more manageable when you understand your teeth. Learning about your teeth can help you understand what the dentist wants to accomplish. This is the anatomy of your mouth and your teeth.

Types of Teeth

A regular adult has 32 teeth (not including wisdom teeth). There are several types of teeth.
Incisors are the eight teeth in the front of your mouth made for biting and chewing. There are four on top and four on the bottom.
Canines are the four sharp teeth shaped like points made for tearing into food. They are on the outside of the incisors. There are two on the top and two on the bottom.
Premolars are in between the canines and the molars and are made for chewing. There are eight molars: four on the top of the mouth and four on the bottom of the mouth.
Molars are the eight flat teeth at the back of the mouth specifically made for grinding. There are four on the top and four on the bottom.

Anatomy of Teeth

The crown is the white outer part of the tooth that we can see and gives the tooth its shape. The enamel covers the crown. It is hard and made of calcium phosphate. The enamel protects the teeth and when it wears down or breaks, it can create sensitivity or pain. Under the enamel is dentin. Dentin is hard tissue. Pulp is underneath the dentin. It’s soft and contains the tissue and blood vessels. The root makes up 2/3 of the tooth and holds the tooth in place by connecting it to the bone. The cementum connects the roots to the gums and jawline with a layer on connective tissue, while the periodontal ligament is tissue that secures the teeth against the jaw.


Now that you understand the anatomy of the teeth, it’s important to practice a healthy dental routine. For more information about your teeth, contact us today to schedule an appointment!
