While teeth are incredibly strong and white, just like bones, and they also store calcium like bones, teeth are not actually made of calcium.
Teeth are made up of a compound called calcium phosphate, which is incredibly tough, making tooth enamel one of the hardest substances in the body.
However, calcium phosphate is not the same as calcium. It's a mineral compound that contains calcium along with other elements like phosphorus and oxygen.
Therefore, while teeth contain a significant amount of calcium, they are not made solely of calcium.
