When you smile in the mirror, you see your teeth. But have you ever thought about what your teeth are made of? Teeth are more complex than they seem. They consist of several components that work together to assist you in chewing, speaking, and staying healthy.
At Agape Dental, a local trusted dentist near you, we feel it is important to learn about your teeth as part of ensuring your smile stays strong. In this blog post, we will discuss the different parts of a tooth, as well as how each part plays a role in your oral health.
The Two Main Parts of a Tooth
Every tooth is composed of two primary components:
- The visible portion of the tooth above the gum line is called the crown.
- The part of the tooth that stabilizes it beneath the gum line is called the root.
Let us now look more closely at the two main parts’ components.
Enamel
Enamel is the outermost layer of your tooth. It is the hardest substance in your body and protects the tooth from decay. Enamel covers the crown and acts like a shield. Although it is very strong, enamel can wear down over time due to acid, sugary foods, or poor brushing habits. Enamel does not regenerate after damage.
Dentin
Under the enamel is a layer called dentin. Dentin is a yellowish substance that is not as hard as enamel. In addition to supporting the enamel, it has small tubes that attach to the tooth’s nerve. If the enamel wears away and dentin is exposed, you may feel sensitivity to hot or cold foods.
Pulp
At the center of the tooth is the pulp. Blood vessels and nerves are found in this tooth’s soft area. The pulp keeps the tooth alive and healthy by supplying nutrients and signals. If bacteria reach the pulp, it can become infected, and you may need a root canal to remove it and save the tooth.
Cementum
Cementum covers the root of the tooth. It is a hard layer that helps anchor the tooth to the jawbone. To stabilize the tooth, it cooperates with the periodontal ligament. If your gums recede, the cementum can become exposed and lead to sensitivity.
Periodontal Ligament
This ligament connects the cementum to the jawbone. It acts like a cushion that absorbs pressure when you chew and helps keep the tooth in place. Healthy gums and bone support this structure and are key to strong teeth.
Types of Teeth and Their Jobs
There are four main types of teeth. Each has its own special function.
- Incisors are the first teeth in the mouth, located in the front of the mouth and designed for cutting food.
- Canines are the pointy teeth located on each side of the incisors, which may be a good option for tearing food apart.
- The premolars are behind the canines and are used primarily to crush and grind up a piece of food.
- The molars are in the very back of the mouth and primarily grind food into smaller particles.
The average adult has 32 permanent teeth. Each tooth serves an important function in chewing and speaking.
Why Tooth Anatomy Matters
Understanding the different parts of your teeth allows you to make more informed dental care decisions. It can help you:
- Avoid cavities and gum disease
- Understand when something feels off
- Knowing treatments like fillings, crowns, and root canals. Converse more confidently with your dentist.
If you are looking for a dentist in Millwood, knowing more about your teeth is a great first step in taking control of your oral health.
Common Problems That Affect Tooth Structure
- Cavities occur when bacteria damage the enamel and reach the dentin.
- Sensitivity occurs in teeth when dentin and cementum are exposed.
- Infected pulp can lead to major pain and may need root canal treatment.
- A cracked tooth can affect any structure and can lead to pain.
- Gum disease can harm and damage the roots and soft tissue support of the tooth.

Frequently Asked Questions
- What are the layers of a tooth?
A tooth is composed of three primary components: pulp, dentin, and enamel. The root of the tooth has cementum covering it, which helps keep the tooth in the jaw via the periodontal ligament.
- Why do my teeth sometimes feel sensitive?
Teeth usually feel sensitive when the enamel has worn down or when the gums recede to cause the dentin or root surface to be exposed.
- Is it possible for enamel to grow back?
No, once enamel is lost, it will not grow back. Fluoride treatments and good oral hygiene will help to strengthen the remaining enamel.
- What happens if the pulp of a tooth gets infected?
Having an infected pulp can be incredibly painful, and it will often be accompanied by swelling. To treat the infection, a root canal is required.
