The parts of a tooth and their functions

Introduction

Our teeth are one of the most important components of our body, responsible not only for helping us chew and eat, but also for allowing us to speak, smile and express ourselves. To understand why they are so important, it is important to explore the structure and function of the parts of a human tooth. Each tooth is made up of different layers, from enamel on the outside to pulp in the center, and each part has a specific function. Understanding the structure and function of these parts we can better appreciate the complexity of our teeth and the important role they play in our overall health.

The different parts of a tooth

• The crown: The upper part of the tooth, located above the gum. This part is not covered by the gum, so it is usually whiter. The crown is covered with dentin and provides nutrition and a protective layer to the roots of the tooth.
• Root: It is the part of the tooth that is under the gum and that helps to keep the tooth in place in the jaw bone
• Pulpa: Soft tissue inside the tooth. The function of the pulp depends on the type of tooth, but it is usually related to the nerves, blood vessels, and other cells that make up the tooth.
• Dentine: The innermost layer of the tooth, located under the pulp. The dentin layer is responsible for the sensitivity of the tooth and provides nutrition to the tooth roots.
• The gum: The tissue that covers the gums, located under the tooth.
• The enamel: The outer layer of the tooth, located above the pulp. The enamel is responsible for the color and hardness of the tooth.
• Enamel: More external layer

This layer of the tooth is the hardest part of the tooth and is usually the first to wear out during childhood. The tooth surface is covered with enamel, which protects the pulp inside so that it is not damaged by the hard foods we eat. The enamel is replaced constantly during childhood due to wear caused by the action of biting the teeth. At the same time, new enamel is formed under the gums, where the teeth will be placed when the person is adult.

• Dentine: The inner layer

The next layer in the tooth structure is the dentin, which serves as an inner layer for enamel. It is what gives the tooth its color and makes it sensitive to pressure. Most of the material in the dentin layer is a substance called collagen. This is where most of the tooth minerals, such as calcium and phosphate, are found.

• Gingiva: On the tooth neck

The gum is the soft tissue that covers the inside of the tooth in the neck. The gum is also responsible for protecting the roots of the tooth and is approximately twice as moist as the rest of the soft tissue. This layer of soft tissue is usually between one and one and a half times wetter than the rest of the gum.

• Pulp: The center of the tooth

Finally, pulp is in the center of the tooth and is responsible for the sensitivity of the tooth to pressure. Most pulp tissue is a substance called collagen. This is where the blood vessels, nerves, and other cells that make up the tooth originate.

The functions of each party

• Crown: Provides protection to tooth roots by covering them with enamel.
• Pulp: It is responsible for the sensitivity of the tooth to pressure as well as its structure.
• Collagen The pulp gives shape and structure. It is responsible for the structure of the tooth, as well as its sensitivity to pressure.
• The Enamel provides the hard outer layer of the tooth and protects the pulp from damage.
• Dentin is responsible for the colour, hardness and structure of the tooth.
