What Is A Dental Tooth Number Chart?

 

A dental tooth number chart is a visual tool that helps dentists and dental hygienists to quickly and accurately identify any tooth in a patient’s mouth. Many patients wonder what is a dental tooth number chart or why they need one. There are several reasons for which it can be beneficial. It is not uncommon for oral disease to spread quickly, especially if it isn’t caught early on; if your dentist does have to remove your wisdom teeth, however, he or she will need to know exactly where each one sits. Having access to a tooth number chart allows them make sure all of your teeth are given an accurate description in order for them to give you quality care.

 

How Are Teeth Numbered?

 

Although there is no hard-and-fast standard when it comes to tooth numbering, one system is particularly common in dentistry. Here’s how it works: start at your top front teeth and number counterclockwise. You’ll skip some teeth because they’re not visible (as seen in Figure 1 below). Repeat for all of your teeth, including any wisdom teeth. Whether you use a tooth chart with numbers or just remember what each tooth is called by its location, you now know how to navigate your way around your pearly whites!

What Are Wisdom Teeth Numbers?

 

If you’re wondering what wisdom numbered teeth are, then you’ve come to the right place. The easiest way to think about it is that there are four wisdom teeth in all—three on one side and one on each side. The third molars usually erupt between 17 and 25 years of age. That being said, some people have all of their wisdom teeth at 12 years old, but more often than not, our jaws just aren’t prepared for them yet. When they do emerge, they come in during a time when many of us don’t visit our dentist (between 16 and 20).

 

What Are The Different Types Of Tooth Numbering System?

 

#0 – #19 Are One-Decimal Densities. These are called deciduous or baby teeth. They are replaced by permanent teeth in sequence. Primary tooth at 6 months and 20 permanent teeth at 16 years old. Adult teeth in their maximum development.

 

What Are Teeth Numbers And Names?

 

Teeth can be named for their positions within our mouths. They are numbered teeth from top to bottom, starting with 1 in front and 2 in back. Then it continues with 3 and 4 on either side of our mouth until we reach 20 at each side. We have a total of 32 teeth: 8 per quadrant (upper left, upper right, lower left, lower right). These names make it easier to reference individual teeth as well as an entire quadrant when communicating with your dentist or other dental professional. For example, it’s much easier to say I lost my third molar than try to give a thorough description of which tooth is missing!

 

Universal Numbering System

 

Most of us have seen dental charts that are used by dentists and other dental professionals to help identify teeth. These charts have been in use for quite some time, but not many people actually know how these charts work or what they are called. This is where a universal numbering system comes into play. This makes things easier because everyone can understand how it works and it is used worldwide. That being said, let’s discuss how exactly we can figure out which tooth we are talking about when speaking of its location on our mouth.

 

Palmer Notation Numbering System

 

This system was created by American dentist, Dr. Marvin Palmer. In 1960, he published a paper in which he introduced a systematic method of identifying teeth and their specific locations within patients’ mouths. The first two numbers represent quadrants (1 to 4) while third digit represents an individual tooth from upper left (1) to lower right (4). Here is how it works: in quadrant 1, top molars are designated by numbers 11 and 13; for permanent canines it’s 16 and 18; bottom molars are 31 and 34. In quadrant 2, it’s 21 for upper left first premolar; 32 for lower right second premolar, 15 for upper left cuspid or canine, 10 for lower right cuspid or canine.

1 – Incisors; 2 – Canines; 3 – Premolars; 4 – Molars, and 5 – Pre-molars. Each tooth is numbered according to its place in your mouth in relation to other teeth. Teeth are also often identified by their names: central incisor, lateral incisor, canine, premolar, molar.

 

Baby Teeth Eruption Chart

 

Most people are born with 20 baby teeth. Babies are born with their first teeth, two bottom front teeth, but it takes about 4 years for all 20 to come in. By age 6, your child will have a full set of 32 permanent teeth. Most adult teeth will be in place by age 12 or 13, and some wisdom teeth may not come in until your late teens or early twenties. Here’s a helpful chart that shows when your child’s teeth will emerge!

 

Permanent Teeth Eruption Chart

 

Teeth Chart Numbers. When your baby teeth fall out, your adult teeth will replace them. Most adult teeth will be in place by age 20 and all permanent teeth should be in place by 25 years of age. These dental charts are a helpful guide to keep track of which tooth is expected when, because when a permanent tooth starts to come in early or late, you may have an underlying problem that should be treated promptly.
