What Are Wisdom Teeth Numbers?


Since these teeth are usually crowded, they have been given a lower number than regular teeth. Instead of being designated as third molars, wisdom teeth are considered to be your third bicuspids, which is why they’re numbered in sets of three instead of four. Even though these teeth may not seem like much trouble at first, it’s best to schedule a visit with your dentist before they have time to grow and cause any problems. Your number system starts with the wisdom tooth on one side of your mouth. This is then followed by two more on that same side of your jaw, and then three on other side. For example: wisdom tooth numbers would be 5-1-2 or 3-4-5.

In dentistry, teeth are numbered from top to bottom on either side of your mouth. When you look at your teeth in their natural position, left then right, each tooth gets a number: upper left (UL) is 1 and upper right (UR) is 2. Lower left (LL) is 3 and lower right (LR) is 4. This means that when you open your mouth really wide, UL1 would be on top – UR2 would be in front.

Universal Numbering System


Dental professionals use a universal numbering system to quickly and accurately identify each tooth in your mouth. Each tooth is assigned a number based on its location in your mouth, regardless of whether it’s an upper or lower tooth. As you start looking into which dentist will provide you with quality dental care, make sure they have experience using proper identification systems to ensure that your teeth are cared for correctly. It could be an added cost if they don’t have all of their bases covered, but it’s one that is worth every penny if it means you avoid misdiagnosis or inaccurate treatments that may not meet your dental needs down the road.


Palmer Notation Numbering System


Numerical Notation In Dentistry- An Illustrated Guide:Teeth are numbered to start from right most teeth followed by left most teeth. Just like as you do in case of writing numbers. In dentistry, we have various systems to number teeth. Usually we consider permanent maxillary central incisors as tooth No.1,then left permanent maxillary lateral incisor as tooth No.2 and next one is first premolar on both sides, then first molar on both sides and so on (Figure 1). But if it comes to extractions these numbering systems become very important because we often need to write about tooth #7 but that number doesn’t mean anything for us by looking at it individually or when you read an extraction report.
