Tooth Anatomy

At Brittney K. Craig, DMD, we believe that knowledge empowers you to care for your smile. Understanding the anatomy of your teeth can help you appreciate the importance of dental care. In this brief guide, we'll explore the intricate structure of your teeth and how each part plays a vital role in maintaining your oral health.

Tooth Structure: A tooth is a complex and remarkable

structure consisting of several essential components:

1. Crown:

The crown is the tooth's visible part that sits above the gumline.

It's covered by a protective layer called enamel, which is

the hardest substance in the body.

2. Enamel:

Enamel is the outermost layer of the tooth and serves as a shield against tooth decay and damage.

It's mineralized and incredibly durable but can still be eroded by acids produced by bacteria.

3. Dentin:

Beneath the enamel lies the dentin, a hard tissue that forms the bulk of the tooth's structure.

Dentin is sensitive and contains microscopic tubules that transmit sensations, making it responsive to temperature and pressure.

4. Pulp:

The pulp is the innermost part of the tooth, located in the pulp chamber and root canals.

It houses the tooth's nerve, blood vessels, and connective tissues, providing nourishment to the tooth.

5. Gumline:

The gumline, or gingiva, is the soft tissue that surrounds the base of the tooth.

It plays a crucial role in anchoring the tooth in place and protecting the sensitive root.

6. Roots:

Tooth roots are hidden below the gumline and firmly anchored within the jawbone.

They serve as support for the tooth and transmit biting forces to the jawbone.


Tooth Function: Each part of your tooth has a specific function that contributes to your overall oral health and well-being:

  • Chewing and Grinding: The crown's shape and the hardness of the enamel allow your teeth to efficiently chew and grind food.

  • Sensation: Dentin and the pulp chamber transmit sensations, helping you sense temperature and pressure changes.

  • Stability: The roots anchor the tooth securely in your jaw, ensuring stability when eating and speaking.


Caring for Your Teeth: Maintaining your dental health involves protecting and preserving these essential tooth components:

  • Good Oral Hygiene: Regular brushing and flossing help remove plaque and protect enamel.

  • Dental Check-Ups: Routine dental visits allow for early detection and treatment of dental issues.

  • Healthy Diet: A balanced diet low in sugary and acidic foods supports tooth enamel.

  • Avoidance of Harmful Habits: Refrain from habits like teeth grinding, nail-biting, and using your teeth as tools to prevent damage.


Understanding the anatomy of your teeth empowers you to take better care of your oral health. By prioritizing dental care and practicing good oral hygiene, you can enjoy a lifetime of healthy and functional teeth.
