The Universal Numbering System , sometimes called the "American System", is a dental notation system commonly used in the United States. Dental charts are normally arranged from the viewpoint of a dental practitioner facing a patient. The patient's right side appears on the left side of the chart, and the patient's left side appears on the right side of the chart. The labels "right" and "left" on the charts in this article correspond to the patient's right and left, respectively. Although it is named the "universal numbering system", it is also called the "American system" as it is only used in the United States. The tooth designated "1" is the maxillary right third molar " wisdom tooth " and the count continues along the upper teeth to the left side. Then the count begins at the mandibular left third molar, designated number 17, and continues along the bottom teeth to the right side.

Universal national tooth numbering system

Dentists refer to a specific tooth using a number or coding more usually than using teeth names. However, for patients it is easier to identify and remember the different teeth by using more descriptive teeth names instead of numbers or other coding. The Universal Numbering System is a simplified method of identifying teeth that is approved and adopted by the American Dental Association. In the universal tooth numbering system, tooth number 1 is the patient's upper right third molar, on the right side of the mouth in the upper maxillary jaw.
