At Fischer Family Dentistry of Norton Shores, we believe that the more our patients know about their teeth, the better they can care for them. Your teeth are not just essential tools for eating—they are also some of the most complex structures in the human body. Knowing more about how teeth function and how they’re built can help you maintain excellent oral health. Let’s take a closer look at the anatomy of your teeth with insights from your trusted dentist in Muskegon.
Primary and Permanent Teeth
Your teeth develop in two stages: primary teeth (also called baby teeth) and permanent teeth (adult teeth).
- Primary Teeth: Most children will have all 20 baby teeth by the age of three. These teeth have thinner roots and enamel, giving them a bright, white appearance.
- Permanent Teeth: Between ages 6 and 12, primary teeth fall out, making way for permanent teeth. By the time you reach adulthood, you should have 28 permanent teeth, with the possibility of four additional wisdom teeth emerging in your twenties, bringing the total to 32 teeth.
Different Types of Teeth and Their Functions
Each type of tooth serves a specific purpose, and their unique shapes reflect their role in chewing and eating:
- Incisors: These are the four front teeth on the top and bottom jaw, used for biting and cutting food. They have a thin, chisel-like edge that makes it easy to bite into food.
- Canines: Also called cuspids, these pointed teeth sit beside the incisors and are ideal for tearing and holding food. Many people think of canines as “fangs” because of their sharp appearance.
- Premolars: Also known as bicuspids, premolars have two points and are located next to the canines. Their job is to crush and grind food, making it easier to swallow and digest.
- Molars: These are the large, flat teeth at the back of the mouth. With multiple ridges, molars are responsible for grinding food into smaller pieces, aiding digestion and preventing choking.
The Three Parts of a Tooth
Every tooth is made up of multiple layers and sections, each with a specific role in keeping your mouth healthy and functioning:
- Crown
- The crown is the visible part of the tooth above the gum line.
- Enamel: This outermost layer is the hardest substance in the human body and protects the inner tooth from decay.
- Dentin: Beneath the enamel, dentin makes up most of the tooth. It’s slightly softer and serves as a buffer between the enamel and the sensitive pulp cavity.
- Pulp Cavity: At the center of the tooth, the pulp cavity contains blood vessels and nerves, which bring nutrients to the tooth and allow you to sense temperature and pain.
- Neck
- The neck is the transition area between the crown and the root, located at the gum line. It connects the visible part of the tooth with the root below the gum.
- Root
- The root anchors the tooth into the jawbone and contains the pulp that feeds and nourishes the tooth.
- Roots vary by tooth type: Molars often have two or three roots, while incisors, canines, and premolars typically have just one.
- The root is cushioned by the periodontal membrane, which holds it in place and absorbs the forces of chewing.
