Collagen also constitutes the tough, elastic fabric of tendons and ligaments, and the reinforcing dentine of tooth.
Emergency care consists of placing a suitable dentine lining material on to the fractured dentine , and so prompt treatment by a dentist within the same working day or at least by the following morning is required.
This dentine is darker than enamel, so teeth appear stained and discoloured.
If the sensitive dentine of the root is exposed, the tooth can become sensitive.
The mineral component of dentine may be any of several materials.
During gnawing, as the incisors grind against each other, they wear away the softer dentine , leaving the enamel edge as the blade of a chisel.
The core structure of the tooth is composed of dentine .
Enamel and dentine defects of genetic origin are rare but are occasionally severe and may take a variety of forms and vary in their inheritance.
Fractures limited to the enamel and small amounts of dentine that are not sensitive may not require immediate treatment but should be checked by a dentist.
Tooth enamel is much less porous than bone and dentine , and it has greater inorganic content, density, and crystallinity.
