Each part of a tooth has its own unique function and properties. These parts include:

* Enamel: The hardest, white part of the tooth which surrounds the visible part of the tooth. Enamel is mostly composed of strong minerals, including calcium phosphate.
* Dentin: The layer underneath the enamel surface and underneath the cementum that forms along a tooth’s roots. Dentin is what makes up most of the tooth’s structure and is made of living cellular material and tissue that contains microscopic tubes. Exposed dentin can cause sensitivity and pain.
* Pulp: Soft tissue found in the center of each tooth. Blood vessels and nerves run through the pulp canal of each tooth. This area is extremely sensitive and is responsible for providing the blood flow and nutrients. If the pulp becomes damaged or infected it can cause a severe tooth ache.
* Root: A tooth’s root is embedded in the jawbone and hold a tooth in place. It enables teeth to withstand the force of biting and chewing. Incisors and canines have one root whereas premolars and molars can contain two or three roots.
* Cementum: Is a layer of calcified substance covering the root of a tooth that attaches the teeth firmly to the gums and jawbone.
