Teeth Numbers and Names: A First Step in Understanding Your Treatment Plan
If you’re new to the dental world, or just want a refresher on teeth numbers and names, this guide is for you. This article will walk you through the basics of dental anatomy, teeth numbers, and different teeth names used in the US and Mexico.

Surveys show that most patients have difficulty understanding one of the most significant documents they are likely to encounter in the course of treatment – their dentist’s treatment plan. The treatment plans are presented based on ADA codes and abbreviated procedure names, not it layman terms you can understand. Unless someone in the clinic explains it thoroughly, it’s a struggle. We want to help you take charge of your own dental care. So let’s start at the fundamentals – teeth numbers and names.
Teeth Numbers Chart
Most of us know the basic tooth names, such as molar, incisor, or wisdom tooth. At the dental clinic, human teeth are identified by their numbers and each teeth are named differently. As shown in Fig. 1 above, the ADA teeth numbering system treats the permanent 32 teeth in a clockwise fashion as seen by your dentist. Teeth numbers 1 – 16 are on the upper jaw, also known as the maxillary arch. Teeth number 17 up to teeth number 32 are in the lower jaw, also known as the mandibular arch. Check this printable teeth universal numbering system below.

As an example, teeth numbers 1, 16, 17, and 32 are your wisdom teeth. Teeth numbers 14 and 15 are your upper left molars. If you are getting cosmetic dentistry using veneers, you usually want to enhance the most visible part, teeth numbers 6 – 11 on the upper and 22 – 26 on the lower. For movie fans, vampires can extend their eye teeth (canines): 6, 11, 22 and 27.
