![]() The same symbol is used to identify the quadrants. Following the same order as for adult’s teeth, children’s 20 primary teeth are lettered “A” through “E” in each quadrant. In children, the Palmer Notation System uses uppercase letters instead of numbers. The quadrants may also be identified by letters, such as “UR” or “URQ” for the upper right quadrant. The teeth in the upper left use a backward “L.” For the bottom quadrants, the “L” is upside-down. The “L” is right side up for the teeth in the upper right. The numbers sit inside an L-shaped symbol used to identify the quadrant. The numbers continue to the right and back to tooth number 8, which is the wisdom tooth (third molar.) In the upper right section of the mouth, for example, tooth number 1 is the incisor (flat, front tooth) just to the right of the center of the mouth. The numbering runs from the center of the mouth to the back. The numbers 1 through 8 and a unique symbol are used to identify the teeth in each quadrant. ![]() In this system, the mouth is divided into four sections called quadrants. So, a child’s first tooth on the upper right would be A and the last tooth on the lower right would be T. This version uses the letters A through T instead of the number 1 through 20. However, most dentists and insurance companies now use a modified version of the Universal Numbering System for children. So, a child’s first tooth on the upper right would be 1d and the last tooth on the lower right would be 20d. In the original system, children’s 20 primary teeth are numbered in the same order, except that a small letter “d” follows each number to indicate deciduous (primary) teeth. If you’ve had teeth removed or teeth are missing, the missing teeth will be numbered as well. If you are missing your wisdom teeth, your first number will be 2 instead of 1, acknowledging the missing tooth. In this system, the teeth that should be there are numbered. Numbering continues again toward the front and across to the tooth farthest back on the bottom right side of your mouth (which is number 32). Number 17 is the tooth farthest back on the left side of your mouth on the bottom. The numbers continue by dropping down to the lower (mandibular) jaw. Numbering continues along your upper teeth toward the front and across to the tooth farthest back on the top left side (which is number 16). Tooth number 1 is the tooth farthest back on the right side of your mouth in the upper (maxillary) jaw. ![]() Internationally the two-digit FDI World Dental Federation notation is widely used. the Palmer Notation Method is used by some orthodontists, pedodontists (child dental specialist), and oral surgeons (originally called the Zsigmondy system after an Austrian dentist of that name who developed the idea in 1861).the Universal Numbering System has been adopted by the American Dental Association and is in use by most general dentists today, and.This means that the filling is on the top right first molar, and the mesial, occlusal, and distal surfaces are involved.Numbering systems have been developed in order to have a standard way of referring to particular teeth (there are more than 32 different systems). L – lingual, the inside surface of the tooth (facing tongue)įor example if your dentist says you need a filling 16MOD. A tooth has the following services:ī – buccal, the outside surface of the tooth (facing cheek) In addition to tooth numbers dentists also describe a tooth or filling by its surfaces. Including wisdom teeth there are 32 adult teeth and 20 baby teeth. For example if you were referring to tooth 51, this is the baby first incisor. Quadrant 6 is the baby tooth version of quadrant 2 and so on and so forth. Quadrant 5 is the baby tooth version of quadrant 1. These are used to identify primary or baby teeth. There are 4 additional quadrants used in dentistry. How about your bottom right wisdom tooth? This would be tooth number 48. Tooth 21 is the first incisor on the top left. For example, tooth number 14 would be the upper right bicuspid. All tooth numbers are a combination of the quadrant and then the tooth number. The 6 is your 6 year molar, the 7 your 12 year molar, and the 8 is your wisdom tooth. Within each quadrant of your mouth there are 8 teeth. If you were facing a person then quadrant 1 is YOUR upper left and then go clockwise and you are going 2, 3, 4. Quadrant 1 is the upper right, 2 is the upper left, 3 is the lower left, and 4 is the lower right. The mouth is divided into 4 sections that we call quadrants. I will also discuss briefly the surfaces of teeth. Have you ever wanted to know what the dentist is talking about when he is reading out a bunch of random numbers? This post will discuss the tooth numbering system that dentists use in Canada.
