Dental Dials

To understand the tooth numbering system, it is first necessary to understand the tooth dials. The teeth are divided into four quadrants, The upper arch has two sections, the upper right and left upper sections, called the first and second quadrants, the third and fourth quadrants belong to the lower jaw.

Dental charts are prepared from the point of view of dentists, making their work easier. Right-hand teeth are shown on the left side of the chart and left-hand teeth are shown on the right of the chart.

If you can understand the dials, you can quickly and easily find a tooth specified in their naming system.

Universal Numbering System

In 1882, German dentist Julius Parreidt proposed the Universal Tooth Numbering System. This system, in which permanent and eruptive teeth are named differently, has been accepted and approved by the American Dental Association (ADA).

Universal Numbering System

This proposed numbering system was found to be successful and became the most used numbering system by dentists in America. However, this system had its drawbacks, it was not sufficient to classify teeth. This numbering system continued to be used for many years as it facilitates the finding of the relevant tooth and is easy to understand.

Notes and Other Information About Teeth

We lose our baby teeth by the age of 13 and we have permanent teeth. By the age of 25, we have 4 extra teeth, called wisdom teeth, which grow in the back of our mouth.

The canine teeth are #6 and #11 on the upper jaw and #22 and #27 on the lower jaw. The reason why canine teeth are called “eye teeth” is that the long root extends almost to the eye socket. They are the first teeth to be eroded, as they are used for biting.

Your third molars come out between the ages of 17 and 21, and if your wisdom teeth need to be extracted, you should not leave them until later ages. The right second molar is called A, the left second molar is given the letter J, and the deciduous teeth are started to be named.

The two upper middle front teeth are #8 and #9 and are defined as the right upper central incisor and the left upper central incisor.

If the dental chart is not prepared from the perspective of the dentist, it can be difficult to use and learn. The universal numbering system is used as a reference as if you have all the teeth in your mouth, even if you have wisdom teeth removed, your upper right wisdom tooth is considered number 1.

The numbering of teeth continues along with your upper teeth until your farthest tooth, number 16. If you count clockwise starting from #17, which is the lower-left wisdom tooth, you will have #32 your lower right wisdom tooth.

Children’s Teeth

Children’s teeth in the upper right are called the first tooth, and the teeth in the lower right are called the last tooth.

The first row of primary teeth is the posterior part of the upper right quadrant, where the right second molar, called A, is on the left posterior aspect of the left second molar dental arch and continues up to the letter J.

The first premolar has sharper, more prominent spikes than the second premolar, and the buccal apex is larger than the palatal apex.

Universal Numbering System
