How to Number Supernumerary Teeth

Some people may have extra teeth in their mouths. These are called supernumerary teeth. You can chart these supernumerary teeth in software (Dentrix) by following these steps.

For permanent teeth:

Add 50 to the closest standard tooth number. For example, a supernumerary tooth that is adjacent to tooth 12, would be entered as 62.

For primary teeth:

Add the letter "S" following the closest standard tooth number. For example: AS

Another easy method (example) of charting the supernumerary teeth in the four quadrants is presented below.

  • In the chart, each quadrant normally contains 8 teeth. Start the counting on the upper right quadrant from right toward left until the counting of 16 permanent teeth is completed.
  • You should continue counting the lower teeth going left to right such as from 17 to 32. (32 is the total number of normal permanent teeth)
  • For charting supernumerary teeth, add 50 to all those numbers.
