  • 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.
