4 Important Facts About Tooth Anatomy

Posted on: October 29, 2018

Have you ever been curious about the structure or anatomy of the tooth? You are not alone. The tooth has different parts with specific functions and features. The major component of the tooth anatomy is the enamel, dentin, roots, root canal chambers and cementum.

When the anatomy of the tooth is compromised, probably from fractured teeth or degraded enamel, the tooth is more prone to cavities. Oral health conditions, including gum diseases, affect the tooth’s health and cause tooth loss. Knowing essential facts about tooth anatomy and the necessary oral health decisions to take should be an important aspect of oral health education for you and your loved ones.

Important facts about tooth anatomy

Tooth Enamel — the hardest substance on the human body

The tooth enamel is the first visible layer of the teeth that serves as a protective shield. It consists of strong minerals like calcium phosphate. These components make it the hardest part of the human body as well as translucent. The enamel is resistant against cavity-causing bacteria, but inadequate oral care can weaken it.

With fluoride treatment, you can strengthen the enamel to keep it healthy and free from cavities.

Cementum — the root’s protector

Cementum is the substance covering the root of the tooth and works like the enamel, but it is softer than enamel. Cementum helps keep the root stable by fusing to the fibers that connect the tooth to the jawbone.

Dentin — susceptible to bacterial invasion

Dentin is located beneath the enamel and under the cementum. It consists of cellular materials and tissues and makes up the highest portion of the tooth anatomy. Dentin is a bone-like material that contains small tubules. Unlike the enamel, dentin is susceptible to cavity-causing bacteria and causes tooth sensitivity.

Root — the teeth’s anchor

Just as tree’s roots anchor it in the round, a tooth’s root functions as an anchor in the jawbone. Holding the tooth down is necessary for it to endure the pressure and force of biting and chewing every day. The root is very sensitive and houses the pulp. The pulp is the part of the tooth responsible for the transfer of blood and nutrients needed to keep the tooth alive.

If the root is compromised, probably due to periodontal disease, the entire teeth are at risk. Root infection mainly happens when bacteria in plaques invade the gum tissue and jawbone. The bacteria or damage can harm the bone supporting the tooth. Once the area is injured due to severe tooth decay or trauma, root canal treatment will be necessary. If no treatment occurs, then tooth extraction will be inevitable.

The root is essential for keeping the oral cavity healthy. Through proper oral hygiene routines, especially brushing and flossing, you will be able to keep the tooth healthy and in a good state.

Educate your loved ones

Knowing important facts about the tooth enamel will give you insights into the causes of oral health conditions to help your children develop proper oral hygiene habits. By showing them the unique biological composition of the teeth, you are also training and improving their knowledge of facts about their body.
