The structure of the tooth is as follows: cementum, root canal, enamel.
The apex is the pointed extremity of a conical structure. The apex can be used to describe the top portion of features on the body such as a tooth, lung, or heart.
The pig tooth has a tubercle structure which causes the tooth to have an uneven surface. This makes it excellent for chewing.
No part of "tooth decay" is a structure or function.
It is one of the 4 components of the mammalian tooth and is to be found just beneath the hard enamel outer layer or in ridges between ridges of hard enamel. Being softer than the enamel, in herbivores (like the elephant) the dentine wears away faster ensuring that the roughness of the tooth surface is maintained as the tooth itself wears away. In omnivores and carnivores, it mechanically supports the enamel surface and protects the tooth pulp and nerves.
Tooth Protecter, Tooth Guardians, Tooth Carers
The hard part of the tooth is actually not a living structure. The living structures are the nerves and blood vessels that are inside the tooth.
Cementum.
A thin periodontal igament that holds the tooth in place.
A canine is a stabbing tooth, an incisor is a cutting tooth, and a molar is a chewing tooth.
The loss of tooth structure by mechanical forces from opposing teeth.
Dentine
It is one of the 4 components of the mammalian tooth and is to be found just beneath the hard enamel outer layer or in ridges between ridges of hard enamel. Being softer than the enamel, in herbivores (like the elephant) the dentine wears away faster ensuring that the roughness of the tooth surface is maintained as the tooth itself wears away. In omnivores and carnivores, it mechanically supports the enamel surface and protects the tooth pulp and nerves.
