Tooth enamel is a ceramic which forms the outer part of the tooth and is one of the four elements that make up a tooth. Enamel is the toughest material in the human body. It is covered by the “crown”. The ceramic protects the tooth, but can be eliminated by tooth decay.
Other major tissues in the tooth are dentin, cementum and pulp which contain the highest percentage of minerals in the body. The enamel on a primary tooth is quite opaque and that is why it appears more white than a permanent tooth color.
