The Three Layers of Your Teeth

Did you know that if your tooth enamel gets damaged, the inner tooth layers become more vulnerable to decay? It’s important to brush and floss daily, but it’s important to visit the dentist regularly, too. Your friendly dentists at Sunrise Dental in Peoria will spot any warning signs and help you prevent enamel loss and tooth decay. 

The Three Layers of Your Teeth

Layer 1: Enamel

This hard outer layer protects your teeth from damage and infections. Made from rock-hard calcium phosphate, our tooth enamel has an even higher mineral content than your bones. The enamel covers the crown, the part of the tooth that is visible above the gumline. Acids from plaque, food, and beverages can harm your tooth enamel, so it’s important to brush and floss regularly.

Layer 2: Dentin

The middle layer of teeth is also composed of calcified minerals. Dentin is harder than bone, but vulnerable unless it is protected by the enamel. Gum diseases like gingivitis make your gums pull away from your teeth, exposing the dentin. Damage to the enamel from plaque or teeth grinding can also expose your dentin. Without the protective enamel, you may suffer tooth pain or sensitivity to heat and cold.

Layer 3: Pulp

The center layer of the tooth, the pulp, contains all of the nerves and blood vessels. Also known as the root canal chamber, this central dental layer is extremely vulnerable. Fractures, cavities and infections that reach the pulp cause extreme pain. Don’t delay—if you have severe tooth pain call us right away! We always do our best to schedule same-day appointments for dental emergencies.
