When visiting the dentist, you may hear them call out a series of numbers. These numbers refer to the teeth in your mouth. The American Dental Association (ADA) has developed a system for numbering teeth that is used by dentists all over the world. This system makes it easy for dentists to identify and discuss specific teeth with patients and other dental professionals.
The ADA numbering system divides the mouth into four quadrants: upper right, upper left, lower right, and lower left. Each quadrant is then divided into eight sections, with each section containing one or two teeth. The teeth are numbered starting from the front of the mouth and working backwards.
