What Is The Tooth Numbering System?

The dental teeth numbers system refers to the tooth positions in the mouth. There are two different numbering systems that dentists use, and both are used on dental x-rays as well as in patient dental records. You may have heard of the FDI World Dental Federation (FDI) numbers or the American Dental Association (ADA) numbers, but do you know what they actually mean? In this article, we’ll go over exactly what each system is, where it came from, and what it’s used for in dentistry today.

What Is A Dental Tooth Number Chart?

A standard chart shows dental numbers and names. It also indicates which teeth work together when biting and chewing food. To use a dental tooth number chart, first identify your tooth by its location in your mouth, as indicated on the left side of each column. Then look at each row until you find your tooth’s name listed in black text. Finally, locate your tooth number in that row—the two- or three-digit number directly to the right of its name.

How Are Teeth Numbered?

Dental teeth numbers and names change depending on who is numbering them. In North America, our molars are numbered from left to right with the front teeth labeled as one, two, three and four. This can sometimes cause confusion for those used to identifying their molars by letter rather than number. In Europe, most of Asia and Africa, teeth are numbered from right to left (or back to front) beginning with 32 then 33 then 34 etc. When it comes to wisdom teeth numbers get a little more complicated.

What Are Wisdom Teeth Numbers?

If you’re a little confused by how teeth numbers and names correspond to tooth chart numbers, don’t worry—you’re not alone. How do we identify specific teeth if they don’t have names like the big one next to your two front teeth? This can be confusing, so let’s break it down: wisdom teeth (also called third molars) are also assigned a number, but that number is determined differently than other teeth. Wisdom teeth are given triplet designations, which means they are identified as 1 of 3 molars in a row or series.

What Are The Different Types Of Tooth Numbering System?

There are three different types of tooth numbering systems: dentist and dental hygienist numberings, Munsell chart numbering system, and another common system used in dentistry. All three systems use a unique numbering system to identify each tooth in your mouth by a set of numbers that correspond to its location within each quadrant and arch, as well as its unique name. Before we get into those numbers, however, let’s go over what teeth are called when they are given individual names.

What Are Teeth Numbers And Names?

The numbering system applies to adult teeth, which all have names and numbers. Numbers indicate where a tooth is in relation to other teeth, while names refer to different types of teeth, like canines or incisors. When referring to an adult tooth’s placement, dentists use letters: For example, wisdom teeth are called lower third molars. And if you have a cavity in one of your bicuspids, your dentist will call it an upper second premolar. Brushing and flossing ensure that our mouths remain healthy throughout our lives—this method is based on understanding how we number our teeth!

Universal Numbering System

In a universal numbering system, there are 28 teeth. There are four main types of teeth that are numbered: incisors, canines, premolars and molars. Incisors include your top front teeth; canines include your bottom fangs; premolars include both sets of back teeth between your two incisors and canines and behind your two wisdom teeth (your second set of adult molars); molars include those behind your premolars and second set of adult molars (your third and final set).

Palmer Notation Numbering System

Dental students learn about Palmer notation when they are first learning about teeth. Essentially, there are numbers for each of your teeth. The tooth number is its official name, but some people refer to them as teeth numbers and namesc. There is a tooth chart adult, which can help people figure out their Palmer notation numbering system so that they know what number goes with each of their teeth. All you have to do is count down from 10 and you will be able. To find your initials on your chart (For example I = 11). You will want to use 1 through 32. Because numbers after 32 aren’t in common use anymore and therefore very little dental professionals. Would be able to understand it if you used those numbers.

Federation Dentaire Internationale Numbering System

There are four primary types of numbering systems used around the world to describe teeth. These include American, European, Universal and World Health Organization numbers. Most people recognize American (also known as A-number) and European (E-number) numbers. Because they are used in English speaking countries like Canada, United States, Australia and some parts of Europe. Lesser known is that a different system called Universal numbering was created. By an international organization called Federation Dentaire Internationale in 1949. This is also sometimes referred to as UDI or FDI. Lastly, there is another recently created method called WHO numbers which stands for World Health Organization numbering system.

Baby Teeth Eruption Chart

Each tooth has a number, starting with one and ending in thirty-two. Although some people refer to first molars as sixth teeth, they are not counted as such because they are not incisors or canines. Instead, first molars have numbers seven through twelve based on which quadrant of your mouth they sit in. They also have corresponding names: mandibular central incisor for number seven, mandibular lateral incisor for eight, maxillary central incisor for nine and maxillary lateral incisor for ten.

Permanent Teeth Eruption Chart

At three months, your baby will have four teeth. And by six months, he or she will have eight—all in their top two rows of teeth. Note that these are deciduous teeth; baby’s first permanent molars will erupt during his or her second year (about age 2-2 1⁄2). Meanwhile, at about 9 months and 3 years respectively, baby’s other two sets of incisors (the front four) will emerge as well. After that come canines at about 12 and 18 months respectively, along with those first pre-molars (second from back) at about 18 and 24 months respectively. Finally—at about 24 months—baby’s third set of molars will begin to appear as well. So, if you’re looking for a tooth number chart, it looks like there are 20 per row on average. Oh yeah: don’t forget baby’s wisdom teeth! They typically erupt between ages 17 and 25. What did we miss? Tell us what else you’d like to know about dental health in babies!
