At Mount Auburn Dental, we believe that understanding the anatomy of your teeth is essential to taking good care of them. The more you know about how your teeth are structured, the better you can maintain your oral health. In this article, we’ll take you through the different parts of your teeth and their functions, so you can appreciate why dental care is so important.
Teeth Types: Primary and Permanent
Your teeth come in two main stages: primary (baby) teeth and permanent (adult) teeth. Primary teeth are the first set you develop, usually emerging by the age of three. These 20 teeth have thinner enamel and shorter roots compared to permanent teeth, which gives them a whiter appearance. These teeth are temporary and will begin to fall out between the ages of 6 and 12 to make room for permanent teeth. By the age of 14, most people will have a full set of 28 permanent teeth, with 32 teeth if they develop wisdom teeth later in life.
Different Types of Teeth and Their Functions
Not all teeth are the same; each type is designed for a specific purpose. Here’s a breakdown of your teeth and their roles:
- Incisors: Located at the front of your mouth, incisors are sharp, flat teeth used for cutting and chopping food. These four teeth in the upper and lower jaws are essential for taking bites of food.
- Canines: Also called cuspids, these pointed teeth are located beside the incisors. Canines are used to tear food and are often mistaken for “fangs” due to their shape.
- Premolars: Premolars, or bicuspids, are located next to the canines and are larger and stronger. They have flat surfaces with ridges, designed for crushing and grinding food to make it easier to swallow and digest.
- Molars: Molars are the flat, wide teeth found at the back of your mouth. They have multiple ridges that help grind and crush food. Proper chewing with your molars is crucial for digestion.
The Layers of Your Tooth
Teeth are built to last and are made up of several layers, each with a unique function. Here’s a breakdown:
- Crown: The crown is the visible part of the tooth above the gum line. It’s made up of three layers:
- Enamel: The outermost layer, which is the hardest substance in the human body, protects the inner parts of the tooth.
- Dentin: Beneath the enamel, dentin is a bone-like material that makes up most of the tooth’s structure. It is slightly yellow and contains small tubes that transmit sensations to the nerve.
- Pulp: The innermost layer, the pulp, contains nerves and blood vessels. It’s responsible for the tooth’s sensitivity and vitality.
- Neck: The neck of the tooth is the part between the crown and the root, located at the gum line. It’s thinner and serves as the transition point between the two sections.
- Root: The root is the part of the tooth beneath the gums that anchors it to the jawbone. It contains nerves and blood vessels within the pulp chamber and is cushioned by the periodontal membrane, which helps hold the tooth in place.
