Are you frustrated with teeth numbers?
Are you looking for an easy way to understand?
Don't worry!
We have got you covered.

Human being grows two sets of teeth in a lifetime.
Milk teeth are known as deciduous dentition, while teeth for adults are permanent, so they are called permanent dentition.
Both the upper and lower teeth are divided into four sections.
A horizontal line is a line to symbolize the mouth. Above the line, the numerator is the upper or maxillary teeth are written and below the line, denominator, we write lower or mandibular teeth.
A vertical line divides into right and left from the midline
. Your right is the patients left and vice versa.
To clear the confusion, make a plus sign. In the second quadrant, a 'L' is formed. so the second quadrant is the patients left

We have three most widely accepted tooth numbering systems
universal system
palmer system
FDI system
alphabets A to Z are used in capitals or uppercase.
Both horizontal and vertical lines are drawn, starting from the maxillary right quadrant proceeding to the left maxillary quadrant, then coming to the mandibular left quadrant and finally to mandibular right.
So in the universal system for deciduous, we mark from Ato T.
In the deciduous alphabet are used, but in permanent dentition, numbers are used from 1 to 32 in the same manner, starting from the right clockwise.
The second system is zigmondy palmer system.
Relate "P" palmer for the plus sign.
alphabets are fixed for a tooth type.
so deciduous teeth for all quadrants from A to E
cental deciduous incisor of all quadrants by A
upto
2nd deciduous molar of all quadrants as E
in permanent dentition, numbers are used from 1 to 8 and fixed for all the quadrants.
central incisor of all quadrants being 1
till
3rd molar of all quadrants being 8
The third system is FDI system. The plus sign is not used here. So it’s good when you want to store data on a computer.
It is also known as a two-digit system. Two digits are given to a tooth. The first digit represents the quadrant, and second digit represents the tooth. The permanent dentition has given 1 2 3 4.

similarly for deciduous dentition from 5 to 8
Maxillary right central is "five-one" and not fifty-one. Similarly, a left maxillary canine is "seven-three", not seventy-three.
I recommend you to practice the tooth number system.
Comment in the section below as per FDI one-six is which tooth?
