Are Human Teeth Ivory?
Human teeth are not ivory, but they are both made from a similar material called dentin. Dentin is a hard tissue that forms the majority of the tooth. It is composed of calcium phosphate and collagen fibers. Ivory, on the other hand, is a hard tissue that is found in the tusks of elephants, walruses, and other animals. It is also composed of calcium phosphate, but it has a different structure than dentin.
Here are some key differences between human teeth and ivory:
- Density: Human teeth are denser than ivory.
- Hardness: Human teeth are harder than ivory.
- Color: Human teeth are white, while ivory is yellow or cream-colored.
- Texture: Human teeth are smooth, while ivory has a rough texture.
- Composition: Human teeth are composed of dentin, enamel, and cementum. Ivory is composed of dentin and a small amount of enamel.
