What are the dental numbers?
The upper teeth are numbered from 1-16 from right to left and the lower teeth are numbered 17-32 from left to right.
Therefore, 1,16,17 and 32 would refer to your wisdom teeth and 6-11 and 22-26 would be your anterior teeth in the upper and lower jaws respectively.
Similarly, 6,11 22, 27 would be the canines and so on..
What are the numbering systems in dental anatomy?
Permanent teeth are also assigned numbers sequentially.
The naming starts from the posterior most region of the upper first quadrant and each tooth is numbered from 1 to 32 in a sequential pattern.
The numbering starts from the third molar tooth where the upper right third molar is assigned the number 1..
What are the numbering systems in dental anatomy?
The three most common systems are the FDI World Dental Federation notation (ISO 3950), the Universal Numbering System, and the Palmer notation.
The FDI notation is used worldwide, and the Universal is used widely in the United States.
The FDI notation can be easily adapted to computerized charting..
What is the anatomy number of teeth?
The permanent dentition consists of 32 teeth.
This is made up of four incisors, two canines (or cuspids), four premolars (or bicuspids), four molars and two wisdom teeth (also called third molars) in each jaw.
If wisdom teeth have been removed there will be 28 teeth..
What is the method of dental numbering?
The uppercase letters A through T are used for primary teeth and the numbers 1 - 32 are used for permanent teeth.
The tooth designated "1" is the maxillary right third molar ("wisdom tooth") and the count continues along the upper teeth to the left side..

Universal Numbering System
The uppercase letters A through T are used for primary teeth and the numbers 1 – 32 are used for permanent teeth.
The tooth designated "1" is the maxillary right third molar ("wisdom tooth") and the count continues along the upper teeth to the left side..
- Permanent teeth are numbered 1-32, starting with the third molar (1) on the right side of the upper arch, following around the arch to the third molar (16) on the left side, and descending to the lower third molar (17) on the left side, and following that arch to the terminus of the lower jaw, the lower right third
- The first thing to realize is dentists use a two-digit numbering system.
So the upper right teeth begin with the number “1” (i.e. 11), the upper left teeth begin with the number “2” (i.e. 21), the lower left teeth begin with the number “3” (i.e. 31), and the lower right teeth begin with the number “4” (i.e. 41). - The quadrants are numbered from 1 through 4: upper right, upper left, lower left and lower right.
Teeth are charted with the quadrant number followed by the tooth number.
In this system, the upper right central would be tooth 1-1, or sometimes abbreviated to 11, while the lower left third molar would be 3-8 or 38.
