Enamel is the most mineralized substance in the entire body. It covers each and every tooth and is composed of minerals, mainly hydroxyapatite. Hydroxyapatite is known as a bone mineral, but it is the calcium-deficient carbonated hydroxyapatite that forms tooth enamel and dentin. Human teeth are made up of multiple layers of hard and soft tissue.
Enamel, dentin, and cement are harder sections, while the pulp is the softest part of the tooth. Teeth and bones are not the same thing. Your teeth are made up of four dental tissues. Three of them: enamel, dentin and cement are hard fabrics.
The pulp of the fourth tissue, or the center of the tooth that contains nerves, blood vessels, and connective tissue, is a soft or non-calcified tissue. In short, no, teeth are not bones. While they may look similar to and be made of similar materials, teeth and bones have a few different attributes that differentiate them from each other. The outer layer of enamel is actually the hardest material on the body, since it's mostly mineral (95 percent).
