Health And Beauty

The tooth numbering system was first developed in the early 1900s and has been used by doctors and dentists worldwide since then. The tooth numbering system, also known as the dental notation system, helps to identify which teeth need to be removed during dental procedures like fillings, crowns, or even orthodontic treatment.

What Is A Dental Tooth Number Chart?

Dental charts are used to number and identify teeth. To create a dental chart, dentists use a numbering system that describes where on your teeth certain areas (known as landmarks) are located. These numbers correspond with what is known as a tooth-numbering system, which indicates specific points of reference for teeth. Most commonly, these are listed from one end of a tooth to another; it’s called an alpha-numeric system. For example, tooth #1 is at its very tip—or most anterior aspect—and is designated by A and 1. Other common numbering systems include: Minnesota, Universal and Ames Landmark.

What Are Wisdom Teeth Numbers?

Wisdom teeth are named as such because they usually appear when a person is in their mid-20s and their wisdom (as people age, their brains become more developed).

Now that you know all of that information, let’s put it together!

What Are The Different Types Of Tooth Numbering System?

Before we get into what each tooth numbering system means, we need to understand that teeth are numbered different ways. In fact, there are three common ways to number teeth: mesio-distal, proximal-distal and disto-lingual. The first way (mesio-distal) numbers teeth from one in front of your nose to four behind it in order as you face a person with their mouth closed and using just their four front teeth. For example, your left central incisor would be one and your right central incisor would be two—meaning they’re side by side in between your nose and mouth.

Dental numbering system images—like those shown here—are used to help patients remember their teeth’s names and positions. Each one shows where each tooth is located on both top and bottom jaws on real people’s mouths, who have agreed to let their teeth be photographed for dental education purposes. ​
