Structure of the Tooth A tooth consists of enamel, dentin, cementum and pulp tissue. The portion of a tooth exposed to the oral cavity is known as the dental crown, and the portion below the dental crown is known as the tooth root..
What are the anatomic parts of the tooth?
The tooth has two anatomical parts, the crown and the root. The crown is the top part that is exposed and visible above the gum (gingiva). It is covered with enamel, which protects the underlying dentine. The root of a tooth descends below the gum line anchoring the tooth in the mouth..
What is the anatomy of tooth pain?
The very center of the tooth is called the pulp. The pulp is packed full of nerve endings, meaning that if decay or infection reaches this part of the tooth, you will experience pain..
What is the set of teeth anatomy?
The permanent dentition is composed of 32 teeth with 16 in each arch. There are eight teeth in each quadrant, composed of two incisors (central and lateral), a canine, two premolars, and three molars. These teeth are referred to as numbers, 1 (central incisor) to 8 (3rd molar or 'wisdom' tooth)..
What is tooth anatomy in detail?
The root of a tooth descends below the gum line, into the upper or lower jawbones, anchoring the tooth in the mouth. Different types of teeth have a different number of roots and root formations. Typically incisors, canines and premolars will have one root whereas molars will have two or three..
Which teeth have 3 roots?
In recent humans, the third root usually occurs on the mandibular first molar (referred to as a .
RM1) but may also occur on the lower second and third molars; we refer to these collectively as
RM (4–6)
During the bell stage, growth and folding of the tooth germ determines the crown shape based on specific-cusp patterning.
Structure of the Tooth A tooth consists of enamel, dentin, cementum and pulp tissue. The portion of a tooth exposed to the oral cavity is known as the dental crown, and the portion below the dental crown is known as the tooth root.
This chart helps identify each tooth in the mouth with a corresponding number. It can help when it comes to brushing your teeth and identifying cavities. A tooth numbering system is a helpful tool for anyone who wants to learn more about their teeth.

Large tooth at the back of the mouth
The molars or molar teeth are large, flat teeth at the back of the mouth. They are more developed in mammals. They are used primarily to grind food during chewing. The name molar derives from Latin, molaris dens, meaning millstone tooth, from mola, millstone and dens, tooth. Molars show a great deal of diversity in size and shape across mammal groups. The third molar of humans is sometimes vestigial.
The pulp is the connective tissue
Part in the center of a tooth made up of living connective tissue and cells called odontoblasts
The pulp is the connective tissue, nerves, blood vessels, and odontoblasts that comprise the innermost layer of a tooth. The pulp's activity and signalling processes regulate its behaviour.
Tooth discoloration is abnormal tooth color
Medical condition
Tooth discoloration is abnormal tooth color, hue or translucency. External discoloration is accumulation of stains on the tooth surface. Internal discoloration is due to absorption of pigment particles into tooth structure. Sometimes there are several different co-existent factors responsible for discoloration.
