What Is The Tooth Numbering System?

by Jakeslessor

It’s easy to spot the front teeth, but how do you spot the back ones? It depends on which numbering system you use, so let’s take a look at the two most popular tooth numbering systems and how they differ. First, let’s discuss the common English system, which identifies each tooth by its location in relation to the front teeth…


What Is A Dental Tooth Number Chart?


A dental tooth number chart will list all of your teeth in sequential order, usually by tooth type. Teeth names chart start at 1 and end with what is called a permanent molar. Each tooth has a corresponding number to indicate its location relative to other teeth in your mouth. If you’re missing a permanent tooth, you can use its number as a guide to replace it. For example, if you need to replace your missing #7 permanent molar, search for an implant, bridge or denture that covers seven teeth.

How Are Teeth Numbered?


Teeth are numbered differently depending on whether they’re in your upper or lower jaw. In both cases, even-numbered teeth are to your left, and odd-numbered teeth are to your right. But there’s a small catch: On lower jaws, even-numbered teeth are on top, and odd-numbered teeth on bottom; for upper jaws, it’s vice versa.


What Are Wisdom Teeth Numbers?


Wisdom teeth are often called third molars, since they typically come in after both first and second molars. And while they come in like other teeth, they do have their own numbering system! First molars are numbers 1 and 2, second molars are 3 and 4. Wisdom teeth come in at numbers 5 and 6. It’s a little confusing for some people—but don’t worry about it too much; your dentist will be able to identify all of your teeth without having to follow any numbering system at all!


What Are The Different Types Of Tooth Numbering System?


Dental records are often coded using a numbering system, usually based on tooth location. However, there are several different numbering systems in use and it’s important to ensure you use the right one. Using an incorrect number can be a bit embarrassing; after all, they may start to wonder if you know what you’re doing. Choosing which system to use is largely a matter of personal preference; most dentists tend to choose between Universal, Modified Universal and American. The key thing is that both you and your dentist agree on which one it is – because if you get it wrong once it’s into their records, then every time you visit them they will have to double check with their staff.
