Palmer's Notation

Palmer's notation is a widely used method to designate individual teeth. In Palmer's notation, your mouth is divided into four parts called quadrants, that is the upper left quadrant, the upper right quadrant, the lower left quadrant, and the lower right quadrant as illustrated in the figure on the right. Then each individual tooth in the quadrant is given a name. For example the two upper and two lower teeth at the center of your mouth are called central's. One then combines the names of the quadrant and the tooth to come up with a Palmer's notation. For example, the central on the upper right side of your mouth is called an upper right central.

The remaining teeth are designated as follows:

Central
The two upper and two lower teeth in the very center of your mouth.
Lateral
The teeth just adjacent to the centrals.
Cuspid
The pointy teeth just behind the laterals. These teeth have one cuspal (or point). Cuspids are also called canines.
First Bicuspid
The teeth just behind the cuspids. These teeth have two cuspals (or points)
Second Bicuspid
The teeth just behind the first bicuspids. These teeth also have two cuspals (or points)
First Molar
The teeth just behind the second bicuspids. These teeth have a level surface with four cuspals.
Second Molar
The teeth just behind the first. These teeth also have a level surface with four cuspals.
Third Molar
The teeth just behind the second molars. These teeth also have a level surface with four cuspals.

Alternative names for individual teeth:

Incisor
Another name for the centrals and laterals
Canine
Another name for the cuspids
6 year molar
Another name for your first molar
12 year molar
Another name for your second molar
Wisdom Tooth
Another name for the third molar
Anterior Teeth
Your centrals, laterals, and cuspids. These are the teeth in the front of your mouth
Posterior Teeth
Your bicuspids and molars. These are the teeth in the back of your mouth.
Deciduous Teeth
Your primary, or "baby teeth"
Primary teeth
The first set of teeth which come in. Primary teeth are also called "baby teeth" or deciduous teeth.
Secondary Teeth
Your permanent teeth, i.e. the second group of teeth to come in.
Quadrants
The four parts of your mouth, that is the upper left, the upper right, the lower left, and the lower right.

Numerical notation for teeth

The numerical notation for teeth is an alternate to Palmer's notation. In this notation, the centrals are designated as 1's, the laterals as 2's, the cuspids as 3's, the first bicuspids as 4's, the second bicuspid's as 5's, the first molars as 6's the second molars as 7's and the third molars as 8's

Universal numerical notation for teeth

The universal numerical notation is an alternative numerical notation for teeth. In this notation, your upper right third molar is designated as tooth#1, and then you number each tooth sequentially moving right to left and down across your mouth.
