The Anatomy of Your Teeth

Posted by CITY FAMILY DENTAL on Aug 18 2021, 07:48 AM

We all know the different organs of our bodies. But are you aware of the different parts of your teeth? Have you ever wondered about their internal structure and function? 

It might seem complicated but educating yourself is the first step toward preventing dental health issues.

In this article, our dental care experts at City Family Dental and Implant Centre in Modesto, California, explain the anatomy of teeth for a better understanding of oral health.

  • Number of Teeth

Children have 20 baby teeth that are shed and replaced by 32 permanent teeth that emerge starting from when they are 6 years old until they are 13. Among these, 8 are incisors, 4 are canines, 8 are premolars, and 12 are molars. Four wisdom teeth also erupt between the ages of 17 and 25. 

  • Parts of Tooth

The tooth consists of the crown and root. The crown is the exposed part of the tooth while the root is embedded in the jawbone and is covered by gums. The different parts of the tooth are:

  • Enamel

The enamel, the outermost layer of a tooth, is made up of calcium phosphate. It is wear-resistant and protects the internal structures of the tooth from physical, thermal, and chemical changes. 

  • Dentin

The dentin lies beneath the enamel and supports its structure. It is responsible for the color of the tooth since enamel is semi-translucent. It consists of tubules that transfer signals from the enamel to the pulp. 

  • Pulp

The pulp is the only soft structure of the tooth, consisting of nerves and blood vessels. Pain due to differences in temperature and pressure is usually caused by stimulation of the pulp. The pulp gives the tooth life by providing nourishment and helping dentin regenerate.

  • Tooth Root

Incisors, canines, and lower premolars have single roots. Lower molars have two roots whereas upper molars have three roots. The dentin and pulp present in the crown extend up to the root. 

  • Cementum 

The outer covering of the root is called cementum. Cementum and enamel meet at the neck of the tooth and this is known as the cementoenamel junction. It serves as a niche for plaque formation. 

  • Periodontal Ligament 

The root is encased in the jawbone through these fibers which run from the cementum to the bone. This ligament provides a soft tissue casing and maintains the proper position of the gums.
