What Is The Tooth Numbering System?

From the top front teeth to the back molars, there are 32 teeth in your mouth, giving you plenty of room to chew and speak clearly. Unfortunately, most people aren’t aware of this fact or else they don’t care about it. Instead, they refer to their top and bottom teeth names chart like incisors and canines instead of the proper names like upper right first premolar and lower left second molar. There are also many who have no idea how tooth numbering works and which specific teeth they’re referring to at all!


What Is A Dental Tooth Number Chart?


The tooth numbering system is a way of labelling and identifying teeth, especially in dentistry. It is used to allow dentists to know what area they are working on by providing them with a quick reference point. This system can be used for upper and lower teeth or just one type of tooth. You will often see dentist use it when referring to ‘the patient’s maxillary left second molar (tooth number)’.


How Are Teeth Numbered?


Dental teeth numbers are unique to each patient. Often, they refer to a certain numbering system; patients should make sure that dentists and dental hygienists know their numbering system. Each tooth in a mouth has been given its own number by dental specialists. This system allows them to easily locate and discuss teeth when they are working on patients’ mouths. How are teeth numbered? This is where things get complicated. With 32 permanent teeth found in adults (20 primary and 12 permanent), it makes sense that there is not just one single method of numbering—but multiple different ways! We will explore them below, so you can be prepared next time you visit your dentist!


What Are Wisdom Teeth Numbers?


Wisdom teeth are a type of third molar. Third molars (also called third bicuspids) typically erupt at around 17 to 25 years of age, although they can erupt as early as 14 or as late as 30. Wisdom teeth are often larger than neighboring teeth and also tend to be angled more towards our cheeks, instead of being in line with our other teeth. These characteristics can cause problems when wisdom teeth try to come in, which is why so many people choose to have them removed. How wisdom tooth numbers work and how they relate to their position in your mouth!


What Are The Different Types Of Tooth Numbering System?


There are three types of tooth numbering systems. This includes a European-Style Tooth Numbering, which starts from one and goes up to 32, as there are 32 teeth on a standard human mouth. Another type is an American-Style which begins at zero and extends to 32, as there are 32 teeth on each jawbone (mandible) of an average adult human being. There is also an Australian system that begins at zero for deciduous (baby) teeth and then progresses to 8 for permanent canines. This method would number all other adult teeth accordingly with 8 being 1, 9 being 2 and so forth until it reaches 32. There are other types of tooth numbering systems in existence but these three will cover what most people have learned in school.


What Are Teeth Numbers And Names?


If you’ve ever looked at a teeth chart numbered and wondered, Why do they number teeth in such an odd way? then let us give you a quick primer on dental terminology. First off, there are four quadrants of your mouth (upper left, upper right, lower left and lower right). Within each quadrant are groups of teeth identified by letters: upper premolars (the bicuspids) and upper molars; lower premolars and lower molars. Each letter is followed by a number: 1 through 8 for bicuspids/molars.


Universal Numbering System


When it comes to identifying teeth, dental professionals use a universal numbering system. Starting with tooth one at each arch, dentist number teeth from left to right and from back to front. So teeth are listed as maxillary left second molar (1-16), maxillary right first bicuspid (17-32) and mandibular first premolar (33-48). Each number represents a tooth in that region of your mouth.


Palmer Notation Numbering System


Many doctors and dentists use Palmer notation to number teeth. This method uses an increasing, fixed-pattern system of numerals (1, 2, 3…), starting at the lower teeth and going around until returning to number 1 on top. It is important for you to know your tooth numbers in Palmer notation in case a dentist or doctor needs to make note of them. Typically, most people have a 20 x 13 tooth structure. To review: Lower left first molar = number 1; Lower right first molar = number 16; Upper left first bicuspid (aka premolar) = number 17; Upper right first bicuspid = number 31. As for your next question: Yes, we can do fillings on both your upper and lower rear teeth!
