What Is The Tooth Numbering System?

Your dentist uses a series of numbers to refer to your teeth, but what do those numbers mean? And why does he or she always use them when talking about your teeth? It all has to do with the International Standards Organization (ISO) and their tooth numbering system. Let’s take a look at how it works and how you can use it to understand dental problems, treatments, and questions you may have about your oral health!

What Is A Dental Tooth Number Chart?

A dental tooth number chart lists your teeth by number and shows where each tooth is located in your mouth. Understanding how to read your dental chart, as well as knowing what each symbol means, can help you keep better track of any issues or concerns you may have with your teeth. Understanding a tooth numbering system can also be very helpful if you’re getting braces or planning to get them because they will give you a clear idea of how all of your teeth are going to look when they’re all straightened out. Since getting braces is usually an ongoing process that takes some time, having a dental tooth number chart on hand can make it easier for you to see exactly what stage of progress your smile is at.

How Are Teeth Numbered?

Humans have 32 teeth, including four wisdom teeth that generally don’t emerge until we’re in our mid-20s. Wisdom teeth are often referred to as third molars, because they come in third behind our two other sets of molars. It’s also common for dentists to number all adult teeth sequentially: 12 top right, 13 top left, 14 bottom right and 15 bottom left. In addition to first through third molars (1–3), we also count each quadrant (upper right 4, upper left 5 and so on). This numbering system applies to both permanent and baby teeth alike.

What Are Wisdom Teeth Numbers?

The wisdom teeth are named because they tend to come in at a time in our lives when we are supposed to have more of a sense of ourselves and our place in society. Wisdom teeth may be required for proper jaw development, but sometimes they become impacted and need to be removed. Dentists typically refer to wisdom teeth by their location, rather than numbering them like other teeth. For example, wisdom tooth #11 may appear between your third molars and wisdom tooth #12 would be behind it (not pictured). If you have no idea what’s going on with your wisdom teeth, let us take a look—your dentist can help you decide if these molars will impact your oral health or if they need to be removed.

What Are The Different Types Of Tooth Numbering System?

There are three different types of tooth numbering systems. One of them is a universal system, which refers to numbering teeth by number from 1-16. This is because there are sixteen teeth in total. Another type is a quadrant system which divides your mouth into four areas: upper right, upper left, lower right and lower left. Each area is then further divided into anterior and posterior quadrants. And finally, there’s also a bilateral system where each side of your mouth gets its own set of numbers as well as an even side and an odd side for each tooth in each set (upper front teeth = even; upper back teeth = odd). Think about how you want to organize yourself before you dive in!

What Are Teeth Numbers And Names?

Teeth are numbered according to where they appear in your mouth. This numbering system is used for both deciduous (baby) teeth and permanent teeth. Teeth are named by their location within a quadrant. For example, one front tooth would be called upper right canine if you’re missing that tooth from that area of your mouth. If you have all four front teeth, then it would just be upper right canine. Permanent teeth by number will show up in place of baby teeth as they fall out or get extracted due to trauma or decay.

Universal Numbering System

To understand how teeth by number, you first need to understand how we refer to teeth. The universal numbering system applies to both baby and adult teeth; no matter their position in your mouth or whether they have yet to emerge, each tooth is given a number ranging from 1 (in your lower jaw) to 32 (in your upper jaw). For instance, primary teeth are often called baby teeth—they’re also referred to as tooth numbers 1 through 8. Permanent adult teeth, also known as tooth numbers 9 through 32.

Palmer Notation Numbering System

A popular dental numbering system, developed by Dr.. Palmer in 1839, is widely used around the world. The letter designations can be confusing—the first tooth on each side of your mouth is a 1 but so are all of your lower front teeth. In addition to A, designations like B or M are sometimes used to refer to lower teeth by number or middle teeth, respectively.
