Introduction

A strong foundation in dental anatomy and terminology is essential for every dental assistant. Knowing the structure of teeth, oral anatomy, and common dental terms enables effective communication with the dental team and ensures accurate documentation. In this blog, we’ll provide an overview of tooth structure, oral anatomy, and key terminology to help you build a solid understanding of the dental field. We’ll also explore how the Dental Assisting Academy of Central Florida (DAACF) equips students with this crucial knowledge.





Tooth Structure


1. The Layers of a Tooth

Each tooth is composed of multiple layers, each serving a unique function:

  • Enamel: The hard, outer layer that protects the tooth from wear and decay.

  • Dentin: The layer beneath the enamel, which supports the enamel and carries sensations to the pulp.

  • Pulp: The innermost layer, containing nerves and blood vessels that provide nutrients and sensation.

  • Cementum: Covers the root of the tooth, anchoring it to the jawbone with the help of periodontal ligaments.


2. Types of Teeth

  • Incisors: The flat, front teeth used for cutting food.

  • Canines: The pointed teeth that tear and grasp food.

  • Premolars: Transitional teeth with flat surfaces for grinding and tearing.

  • Molars: The large, flat teeth at the back of the mouth used for grinding food.



Oral Anatomy


1. Key Components of the Oral Cavity

  • Gums (Gingiva): Soft tissue that surrounds and protects the teeth.

  • Palate: The roof of the mouth, divided into the hard palate (front) and soft palate (back).

  • Tongue: A muscular organ essential for speech, chewing, and swallowing.

  • Salivary Glands: Produce saliva to aid in digestion and maintain oral health.


2. Supporting Structures

  • Periodontal Ligaments: Connect the teeth to the jawbone and absorb shock during chewing.

  • Alveolar Bone: The part of the jawbone that holds the teeth in place.



Common Dental Terms


1. General Terms

  • Plaque: A sticky film of bacteria that forms on teeth and can lead to decay and gum disease.

  • Tartar (Calculus): Hardened plaque that requires professional removal.

  • Occlusion: The way the upper and lower teeth fit together when the mouth is closed.


2. Restorative Terms

  • Filling: A material used to restore a tooth after decay removal.

  • Crown: A cap placed over a damaged or decayed tooth to restore its shape and function.

  • Bridge: A fixed restoration that replaces one or more missing teeth.


3. Diagnostic Terms

  • Radiograph (X-ray): An image used to detect issues like cavities, bone loss, or impacted teeth.

  • Probing Depth: The measurement of the space between the teeth and gums, used to assess gum health.
