# The Universal Numbering System For Teeth: A Tooth Chart With Numbers

Your dentist gave you an abbreviated version of a very important chart when you first got your teeth cleaned and examined, right? The Tooth Chart with Numbers by Orathaiwan Thanachaiyong was developed to give dentists around the world a universal way of understanding which tooth they’re working on during dental procedures so they can provide patients with the best care possible. In fact, The Universal Numbering System has been adopted internationally and includes many symbols not traditionally used in other dentistry systems.

## The Universal Numbering System For Teeth

Tooth charts have existed since the 18th century. They’re helpful to dentists and denture makers as a reference when communicating about teeth. It’s also helpful for people who want to understand what their dentist is talking about when they go in for a checkup. These days, tooth charts use numbers instead of letters to indicate where on the chart the tooth is located. The tooth chart numbers are used in dental offices all around the world to help everyone understand what’s going on in their mouths.

Tooth chart numbers are found at the top of every tooth chart, and they show how many teeth there are in each section of the mouth. For example, if you look at the very first set of teeth on this chart (teeth 1-12), you’ll see that there are 12 rows and 16 columns. That means that there will be two rows with one tooth in them (the bottom row), four rows with two teeth in them (the next three rows), four rows with three teeth in them (the next three rows), four rows with four teeth in them (the next three rows) and one row that has five teeth. Each number corresponds to which row it is within its column, so 8 represents the third row from the bottom within its column. 9 represents the third row from the bottom within your second column from left to right.

## How To Read A Tooth Chart With Numbers

A tooth chart is a chart that assigns numbers to teeth. These charts use two different numbering systems and the universal numbering system is based on the fact that the right-hand side of your mouth has four teeth numbered from 1 to 4, and the left-hand side has four teeth numbered from 16 to 19. The numbers are based on how they line up about your face.

#1 – The first tooth on the right-hand side, when looking at your mouth in front of you.

#16 – The first tooth on the left-hand side, when looking at your mouth in front of you.

#2 – The second tooth on the right-hand side, when looking at your mouth in front of you.

## What The Numbers Mean

Each tooth has a number that corresponds to its location in the mouth. The numbering system is universal, meaning it works regardless of whether you’re looking at a top or bottom row of teeth. The following chart includes numbers, descriptions, and illustrations to make understanding easier.

1 – Central incisor

2 – Lateral incisor

3 – Canine (cuspid)

4 – First premolar (bicuspid)

5 – Second premolar (bicuspid)

6 – First molar (premolar)

7- Second molar (premolar)

## Why The Universal Numbering System Is Used

To understand why the universal numbering system is used, it’s important to know what a tooth chart is. A tooth chart is a diagram of a person’s mouth that shows the positions and names of their teeth. The universal numbering system was created to standardize tooth charts and make them easier to read. The numbers on the left represent the teeth themselves, while the numbers on the right represent their corresponding position on an upper or lower jaw.
