Teeth Names and Numbers: Diagram, Names, Number, and Conditions

An adult human being has 32 teeth, and all these have their teeth names & numbers which are given based on their set, arch, class, type, and side.

There are two sets of teeth in human beings, one set is primary or baby teeth and permanent or adult teeth. The set of teeth that replaces primary teeth are called succedaneous or permanent dentition which is a group name.

Teeth Names are also given depending on the arch a tooth is found in; maxillary is the name given to the teeth in the upper jaw and mandibular to those in the lower jaw.

There are four classes of teeth namely: incisors, canines, premolars and wisdom teeth.

Children teeth are otherwise known as deciduous teeth also have the same names except for wisdom teeth which normally come out at the age of eighteen.

The upper teeth of the adult have the following names:

  • Central Incisors.
  • Lateral Incisors.
  • Canine (cuspid).
  • First premolar (first bicuspid).
  • Second premolar (second bicuspid).
  • First Molar.
  • Second Molar.
  • Third molar (wisdom teeth).

The lower teeth consist of third molar (wisdom teeth), the second molar, first molar, second premolar (first bicuspid), canine (cuspid), lateral incisor and nuclear incisor.

Also, baby teeth also have their names which include the following upper teeth: central incisor, lateral incisor, canine (cuspid), first molar and second molar.

The lower teeth names are second molar, first molar, canine (cuspid) lateral incisor and central incisor.

Teeth Names and Locations

Teeth names locations are in each quadrant of the mouth. Each of the quadrants contains eight permanent teeth namely: 2 incisors, one cuspid, two bicuspids, and three molars.

The central incisor is located to the side of the midline because it is centrally placed in the arch.

Beside the central incisor is the lateral incisor. It is followed by the cuspid and the two bicuspids (the first and the second bicuspid).

The last three molars followed the second bicuspid. Also, teeth are located by referring to them as either anterior or posterior.

The anterior teeth are located in the front of the mouth (the incisors and the cuspids). They are also visible when a person smiles.

On the other hand, the posterior teeth are located at the back of the mouth (bicuspids and molars). To facilitate easy identification of each tooth, the names and numbers are not enough; each tooth needs to be identified through the quadrant it belongs

Teeth Names in Human Mouth

Teeth names in human mouth are given according to their anatomic shape or letter or number.

Their names should be recognized fully to avoid confusion and to facilitate quality dental care (for example, right mandibular second molar). Given that there are four-second molars, naming the quadrant (right mandibular) which specifies the second molar makes it easy to recognize.

The human teeth are arranged symmetrically in the mouth, and it is possible to know them by names. Read more about human teeth names and their functions in this post.

Dentists have designated each tooth with name hence, teeth names in English. Cuspids are synonymous with canines while bicuspids are also known as premolars.

teeth numbers and names

Six-year molar is also called first permanent molar. The twelve-year molar is used synonymously with second permanent molar while the wisdom teeth (so-called because of their late eruption) are called third molars.

The teeth in the front of the mouth such as incisors, lateral incisors, and canines are called anterior teeth.

Posterior teeth comprise of teeth located in the back of the mouth, and they are known as premolars and molars. The mandibular is the name given to the teeth in the lower jaw, while maxillary is the group name of the teeth in the upper jaw.

Teeth Names and Positions

Teeth name position in the mouth makes it easier for the dentists to identify them for treatment. The shapes of the teeth help in positioning them.

Teeth are given names by the positions they occupy in the mouth. Each of these teeth is either positioned in the lower jaw or upper jaw.

Those who are in the lower jaw are known as mandibular, and those in the upper jaw are identified as maxillary.

Also, the side of the face (i.e., right or left) the teeth are positioned determines their names. The maxillary incisor is positioned distally from both maxillary central incisors of the mouth and mesially from both maxillary canines.

Mandibular central incisor is situated in the jaw adjacent to the midline of the face. The mandibular lateral incisor is placed distally from both mandibular central incisor and mesially from a mandibular canine.

The maxillary and mandibular canines are positioned three teeth from the midline, and they separate the premolar from the incisors.

Teeth Names and Their Functions

Human teeth names are associated with their functions. The teeth are categorized into four; they have a typical appearance and perform specific options.

They perform these functions according to their shapes and morphology.

Human species are omnivorous because they eat both plant and meat and this particular characteristic demands two specific types of teeth namely; incisors also referred to as cutting teeth are used to cut foods into smaller pieces to facilitate inward movement into the mouth.

Teeth names and their functions

For the face teeth, the area nearest to the lip is known as the labial surface. For the back teeth (premolars and molars), the area that faces the checks is known as the buccal surface, and the chewing place is known as the occlusal surface.

There are different kinds of actual teeth, each of which performs a unique function:

  • Canines: The canine teeth are the quick teeth placed on either part of the incisor’s side. Canine teeth (also called cuspids) job combine with the incisors to bite and tear food.
  • Lateral incisors: The four lateral incisors are placed next to the middle incisors on both arches, one on either side. These teeth have fast incisal edges used for tearing food.
  • Central Incisors: The middle incisors are the face teeth. Adults have four middle incisors; 2 on the lower and two on the upper arches. These teeth are fast and shaped like a chisel for cutting food.
  • Premolars: The premolars (also called bicuspids) and the eight teeth placed next to the cuspids; 2on each side of the mouth, four on the lower arches and four on the upper arches. These teeth are little than the molars and have two cups on the biting location for crushing and tearing food. The premolars nearest to the incisors are known as the initial premolars, while the ones nearest to the molars are known as the 2nd premolars.
  • Molars: Molars are the big teeth with four cups placed in the mouth back behind the premolars. Adults have 12 molars, with 6 in the lower and 6 in the upper arches; 3 on each side of the mouth. Molars have flat, wide surfaces for chewing, biting, and grinding food.
  • Wisdom teeth: which are added among the molars are the final four molars that most adults grow. These teeth are placed in the extreme back of the mouth, 2 in the upper and 2 in the lower arches. Wisdom teeth erupt during the teen years but can grow at any time. Not all wisdom teeth need extraction.

The average adult has thirty-two actual teeth. According to the American Dental Association, each tooth is made of several parts: enamel, dentin, cementum, and pulp. The list of teeth names, their functions, and their development are as follows:

  • Incisors. Incisors are a Person with eight front teeth, with four on top and four on the bottom. The 2 in the center are the middle incisors, while the two on either side of the central incisors are known as lateral incisors. These initial teeth are later changed by the same number of adult incisors.
  • The big function is to bite food. Babies grow their incisors at approximately six months old. After the initial incisors fall out between ages 6 and 8, the actual incisors emerge.
  • Canines. Canines are fast teeth placed outside the incisors. Adults and children have four canines, two on the top and two on the bottom, to support tear their food. Canine’s primary appears when a kid is approximately 16 to 20 months old. The actual lower canines come in at approximately ten years old, and top canines erupt between 11 and 13 years old.
  • Premolars. Premolars also knew as bicuspids can tear and chew food. They are somewhat flat with ridges on the peak, and there are four on each side. The premolars are completely developed by approximately 10 to 11 years of age.
  • Molars. Molars also grind and chew food, yet they are powerful than premolars, and the job with the tongue to support swallow food. These 12 teeth are placed in the mouth back, and they start to appear in kids at approximately 12 to 15 months old.
