Why is enamel important for tooth health?

Enamel is the outermost protective layer of the tooth and is the hardest substance in the human body. It acts as a shield against physical wear and tear, acidic foods, and temperature changes. Since enamel does not contain living cells, it cannot repair itself once damaged. Maintaining it through brushing is crucial for preventing cavities and sensitivity.

What is the role of the pulp cavity?

The pulp cavity is the soft center of the tooth containing blood vessels and nerves. Its primary role is to provide nutrients to the tooth and sense external stimuli like heat or cold. If bacteria reach this area due to decay, it can cause severe pain and infection. Often, a root canal is needed to save a tooth with infected pulp.

How does the jaw bone support dental health?

The jawbone provides the structural foundation that holds the roots of your teeth firmly in place. Healthy bone density is required to withstand the pressure of chewing. If a tooth is lost, the surrounding bone can begin to shrink or resorb. Regular dental checkups ensure both your teeth and the supporting jaw bone remain strong and functional.

About this human tooth anatomy template

This template provides a clear visual breakdown of the internal and external structures of a human tooth. It is designed for students and educators to study dental components like the enamel, dentine, and root system efficiently and accurately.

The Crown

The crown is the visible part of the tooth above the gum line. It is primarily responsible for the mechanical breakdown of food and is protected by the hardest substance found in the human body.

Enamel
Dentine
Pulp cavity
Blood vessels

The Neck

The neck serves as the transition zone where the crown meets the root at the gum line. It is a vital area for dental health because gum disease often starts in this specific region.

The Root

The root is the portion of the tooth embedded within the jaw bone. It anchors the tooth securely and contains the essential nerve and blood supply that keeps the internal living tissue healthy.

Cement
Nerve
Jaw bone
