Teeth are made of what?

Answer 1

Teeth are made up of 3 hard tissues and 1 soft tissue.

The hard tissues are:

1. Enamel - The hardest tissue in our body; has a hardness value of 350-500 KHN (Knoop Hardness Number)
2. Dentin - Hard tissue which is harder than bone but not enamel. Hardness value is 60-70 KHN. Dentin forms bulk of the tooth.
3. Cementum - Hard tissue which is similar to bone but is avascular (without blood supply). Hardness value is similar to bone - 50-55 KHN.

The soft tissue of the tooth is pulp, which is highly vascular and essentially comprises fibroblasts, collagen fibres, blood capillaries and nerves.

Answer 2

Teeth are made up of several different layers and tissues, including enamel, dentin, and cementum.

Enamel is the outermost layer of the tooth and is the hardest and most mineralized substance in the body. It is made up of hydroxyapatite crystals, which are tightly packed and highly organized to give enamel its strength and hardness. Enamel covers the crown, or visible part, of the tooth and helps to protect the tooth from the effects of biting, chewing, and grinding.

Dentin is the layer of the tooth underneath the enamel. It is a hard, bony tissue that makes up the bulk of the tooth and is composed of small, interconnected tubules that contain nerve fibers and blood vessels. Dentin is less hard and mineralized than enamel, but it is still an important part of the tooth that helps to provide structure and support.

Cementum is a thin layer of hard, calcified tissue that covers the root of the tooth. It is similar in structure to bone and helps to anchor the tooth in place within the jawbone. Cementum is softer and less mineralized than enamel or dentin, and it is important for protecting the tooth's root and supporting the attachment of the periodontal ligament, which holds the tooth in place.

In addition to enamel, dentin, and cementum, teeth also contain a pulp chamber, which is a small, hollow space at the center of the tooth that contains nerve tissue, blood vessels, and connective tissue. The pulp chamber is protected by the outer layers of the tooth and helps to nourish and support the tooth.
