The Digital Dentist

We often think that the teeth is merely the part which is visible about the gum. However, that is only a portion of the whole and it is referred to as the crown. The tooth also has a neck lying at the gum line, and a root which is below the gum. The enamel which is harder than bone, coats the crown to protect the dentine. The dentine which is slightly softer has tiny tubules connected to the central nerve of the tooth. The pulp carry nutrients to the tooth. This part has nerves that can sense hot and cold substances.
