The part of the tooth that is inside the gum is called the root.
Understanding Tooth Anatomy
A tooth is a complex and essential part of our oral system, designed for chewing, speaking, and contributing to facial structure. Each tooth is composed of several layers and distinct sections, each with a specialized role. Understanding these parts helps appreciate the importance of proper dental care.
The Root: The Hidden Anchor
The root is the foundational part of the tooth, securely embedded below the gum line and into the jawbone. It is not visible under normal circumstances. The primary function of the root is to provide a strong anchor, holding the tooth firmly in place. Depending on the tooth type, there can be one or multiple roots. For instance, front teeth typically have a single root, while molars often have two or three.
The Crown: The Visible Part
Above the gum line is the crown, which is the visible portion of the tooth. It is the part you use for biting and chewing food.
- Enamel: The outermost layer of the crown is made of enamel. This is the hardest substance in the human body, acting as a durable protective shield against daily wear and tear, as well as against decay.
- Dentin: Beneath the enamel lies the dentin, which forms the bulk of the tooth structure. Dentin is a yellowish, bone-like material that is softer than enamel but harder than bone. It contains tiny tubules that transmit sensations, such as pain or temperature, to the pulp.
The Pulp: The Life Source
Deep within the center of the tooth, surrounded by dentin, is the pulp. This soft tissue extends from the crown down through the root.
- Blood Vessels: The pulp houses the blood vessels that supply vital nutrients to the tooth, keeping it alive and healthy.
- Nerves: Also located within the pulp are the nerves, which are responsible for sensation, allowing you to feel hot, cold, or pressure stimuli.
Key Components of a Tooth
To provide a clear overview, here's a table summarizing the main parts of a tooth and their respective roles:
| Part of Tooth | Location/Description | Primary Function |
|---|---|---|
| Crown | Visible part above the gum line | Used for chewing, biting, and provides tooth's appearance |
| Enamel | Outermost layer of the crown | Protects the tooth from wear, decay, and damage |
| Dentin | Layer beneath enamel (crown) and cementum (root) | Forms bulk of tooth, supports enamel, transmits sensation |
| Pulp | Innermost chamber within the crown and root | Contains blood vessels and nerves, nourishes the tooth |
| Root | Part inside the gum, embedded in the jawbone | Anchors the tooth firmly in place, provides stability |
| Cementum | Thin layer covering the root surface | Helps attach the tooth to the surrounding jawbone via ligaments |
Maintaining Root and Gum Health
The health of your roots and gums is paramount for overall oral well-being. The gums protect the delicate root structures, and maintaining their health prevents issues like gum disease, which can lead to root exposure and tooth loss.
Here are practical tips for safeguarding your roots and gums:
- Brushing Effectively: Brush your teeth twice a day for two minutes each time using a fluoride toothpaste. Pay attention to the gum line, gently cleaning where the tooth meets the gum.
- Daily Flossing: Flossing removes plaque and food particles from between your teeth and beneath the gum line, areas that your toothbrush can't reach. This is crucial for preventing gum inflammation around the roots.
- Regular Dental Check-ups: Visit your dentist for routine cleanings and examinations. Professional cleanings remove tartar buildup that brushing and flossing cannot, protecting your gums and ensuring your roots remain healthy and secure.

By understanding the vital role of the root and practicing consistent oral hygiene, you can contribute significantly to the longevity and health of your teeth.
