Learn About The Universal Dental Numbering System
It’s important as a dental assistant to know and understand the universal dental numbering system. Most adults have 32 teeth also referred to as permanent teeth. The first set of teeth which appear during childhood are called primary teeth. There are 20 primary teeth which on average start erupting by the age of 6 months, and can fall out as early as age 4. The last primary tooth is typically gone by age 11. The last four permanent teeth usually erupt by the age of 25.
Both the maxillary and mandibular arches contain similar types of teeth. There are four types of teeth present in the upper as well as lower jaw. These are called incisors, canines, premolars and molars. In dentistry, permanent teeth are identified with the help of a standard numbering system. This video explains and demonstrates the standard classification of the teeth with the popular numbering system. The said universal dental numbering system is mainly used in the United States and starts by numbering the teeth at 1 from the upper right part (third molar) and ends at the lower right jaw with tooth #32 (third molar).
As a dental assistant, you will be working with both dentists and dental hygienists and need to be able to properly communicate with them. Dentists and hygienists refer to a teeth by specific numbers and this video will teach you the correct way to do so.
