Read the following article to find out more details about the two types of human teeth. Teeth anatomy Tooth structure. The four groups of teeth are not identical but they all share a typical and general tooth anatomy as follows.
A normal adult mouth has 32 teeth which except for wisdom teeth have erupted by about age 13. Incisors 8 total. The middlemost four teeth on the upper and lower jaws.
Canines 4 total. Here are the main components of a tooth. This is the top part of the tooth.

In mammals an outer layer of enamel which is wholly inorganic and is the hardest tissue in the body covers part or all of the crown of the tooth. The middle layer of the tooth is composed of dentine which is less hard than enamel and similar in composition to bone. The dentine forms the main bulk or core of each tooth and extends.
Each tooth has a crown and root portion. The crown of each tooth projects into the mouth. The root of each tooth descends below the gum line into the jaw.
The crown is covered with enamel and the root portion is covered with cementum. The crown and root join at the cementoenamel junction CEJ. This junction also called the cervical line.
The long axes of teeth are aligned so that functional occlusal surfaces act through or close to the axes 6. The periodontium is intact there is no detectable fremitus or tooth mobility 7. The occlusion is stable teeth do not migrate or change position only slow compensatory movements 8.
The teeth do not exhibit additional wear beyond what would be expected for. The Anatomy of a Tooth. Hard calcified tissue covering the dentin in the crown of tooth.

Maxillary Second Molar The average tooth length of this tooth is 20 mm Pulp Chamber It is similar to maxillary first molar except that it is narrower mesiodistally Roof of pulp chamber is more rhomboidal in cross-section and floor is an obtuse triangle Mesiobuccal and distobuccal canal orifices lie very close to each other sometimes all the three canal orifices lie in a straight line. The tooth anatomy includes the crown which is the portion of the tooth exposed to the oral cavity and one or more roots which are enveloped in bone and the periodontium. The crown of each tooth has 5 surfaces as follows.
Buccal facing the cheek or lip Lingual facing the tongue Mesial between the teeth. The bulk of the tooth is comprised of dentin a cream colored calcified tissue a framework of minerals and organic material Formed by odontoblast cells which reside on the periphery of the pulp.
