Are Your Teeth Bones?

Posted on 10/15/2018 by Downtown Dental Care Office
Are Your Teeth Bones?While teeth are white, hard surfaces they are not considered bones in the strictest form of the word. Natural teeth are one of the strongest parts of our bodies and can tolerate enormous pressure when chewing on hard objects.

Anatomy of a Tooth

Despite what many people may think, the tooth is made of several layers, but only the crown is visible. This is the top of the tooth that is exposed above the gum line and allows a person to eat and speak properly.

Your teeth are made of two main parts, the crown and the root. Each one of these is also made of other layers that make up the entire tooth.

•  Enamel. The crown of the tooth is covered by a hard, white layer called the enamel which is responsible for protecting your teeth from harmful bacteria. The enamel is the first line of defense against tooth decay.
•  Dentin. Located immediately under the enamel, the dentin is softer and more like bone. The dentin reaches all the way down to the root.
•  Pulp. The pulp is responsible for bringing nutrients that the tooth needs to survive. It contains the nerves and blood vessels that feed those nutrients to your teeth.

The root of the tooth is made up of several layers.

•  Cementum. This partially covers the root of the tooth below the gum line.
•  Blood vessels. These provide minerals and nutrients your teeth need to stay alive.
•  Periodontal ligament. The ligaments keep the root of the tooth in place in the jawbone.
•  Lateral Canals. These are an extension of the root canal that are difficult to detect during treatment.
•  Nerve. This is the innermost layer of the tooth and causes pain when infected.

Teeth and bones are not equal and even though many people think they are because teeth are so strong and hard. However, the anatomy is completely different.
