Our teeth allow us to chew, speak, and live active lives. Most people know very little about their teeth and the complex system involved in their unique design. Understanding the parts of your teeth may give you a different perspective and greater appreciation of their true value.

Crown
The part that most people see, a tooth’s crown is the area above the gums. How a crown is shaped determines the tooth’s function. For instance, molars have flat surfaces, which are ideal for grinding.

Gum line
The location where the gums and tooth meet. This area is susceptible to plaque and tartar build up, so proper brushing and flossing are critical to optimal gum health.

Enamel
Known as the hardest substance in the human body, enamel is the outer layer of your teeth. Enamel protects teeth from environmental forces such as acid and decay-causing agents.

Dentin
Composing the bulk of the tooth, dentin is a yellow, bone-like material under the enamel. Though it feels solid, dentin is actually porous and contains millions of small tubes that feed directly into the pulp.

Pulp
Considered the nerve center of the tooth, the pulp contains the soft tissue and blood vessels. The pulp provides nourishment that keeps the tooth healthy. When decay hits the pulp, people usually experience pain.

Root
Embedded in the bone, the root comprises two-thirds of the tooth and anchors the tooth in place. Usually, the roots are twice as long as the crown, the part visible to the naked eye.
