Tooth 11 Decay: Everything You Need to Know

In tooth number systems, tooth number 11 is the canine tooth. Which are also called cuspids, eye teeth, and fangs. In the Palmer Notation Method or the FDI World Dental Federation notation, tooth number 11 refers to the upper right maxillary cuspid, also known as the upper right maxillary canine. It is now easy for dentists to identify the teeth by their name or number, all thanks to the tooth numbering system followed across the globe.

Tooth 11 Location

The tooth is between tooth number 10, which is the lateral incisor from the right in the upper jaw, and tooth number 12, which is the first premolar.

The first canine in the upper quadrant of your mouth, counting the teeth starting from the left, is tooth number 6, and the second canine is tooth number 11. There are a total of two canine teeth in the upper right and left quadrants of the upper jaw. check out more details about tooth 11 here.

tooth 11 (2nd canine)

Tooth 11 is the number for 2nd canine in universal tooth numbering system. While FDI and Palmer has a different numbers for tooth number 6, given below:

  • FDI number for tooth 11: The number 23 is assigned to tooth number 11 in FDI dental numbering system
  • Plamer number for tooth 11: The number 3 is assigned to tooth number 11 in Palmer dental numbering system

The Function of the 11th Tooth Number:

The function of tooth number 11 is the same as tooth number 6. Both are canine teeth, both are pointy, and both have a single root.

  • Both are used for biting and tearing food. 
  • Tooth number 11 is also responsible for the stability of your facial structure.
  • Help in the proper alignment of the upper and lower jaws.

Upper and Lower Dental Quadrants

In a human mouth, there are a total of 4 quadrants, and each quadrant consists of 1 canine tooth. The upper quadrant is divided into the left and right upper quadrants, called the top right and top left quadrants, respectively. Both quadrants consist of 2 incisors, 1 canine tooth, 2 premolars, and 3 molars, and the last molar is a wisdom tooth.

The lower quadrant is also divided into 2 portions: the left and right lower quadrants. The numbering of the tooth types is the same for all the quadrants.

Eruption Age of Tooth Number 11

The eruption age for both the baby teeth and the permanent teeth for tooth 11 is mentioned below in the chart:

Tooth 11Eruption Age
Baby tooth eruption age16-12 months
Permanent tooth eruption age11-12 years
Tooth Number 11 Eruption Age

The approximate eruption age for the second canine tooth, which is tooth 11 can vary for different people in both baby and permanent teeth. The reason for the varying timing can be genetic or environmental. Even adults or babies with less strength are victims of late tooth eruption.

Eruption Sequence

The permanent 11th Teeth generally comes in after the central incisors (teeth 8 and 9), the lateral incisors (teeth 7 and 10), and the first premolars (teeth 4 and 13). It is one of the last top teeth to come in.

Tooth number 11 is typically the last tooth to erupt in the upper jaw.

Most of the time, 11th teeth is impacted and unable to erupt or erupt properly. So tooth number 11 or other canine teeth require proper orthodontic treatment for the stability and proper alignment of the other teeth in the upper and lower jaws.

Implications of the palatal position of tooth number 11

It may happen to some people that the tooth number erupts at the palate, which is the roof of the mouth. This eruption can cause instability in the positioning of the other teeth. This eruption needs orthodontic treatment to avoid many dental problems. And one of them is the proper alignment of all the teeth in the mouth.

The reason we have talked a lot about the alignment of the teeth in the mouth is that improper alignment of teeth affects not only the look of your mouth but also your smile.

The Importance of Canine Teeth in Orthodontic Treatment

Tooth number 11 or any other canine tooth is of high importance in orthodontic treatment. The upper canine teeth, or teeth 11, are used as anchor teeth. Their strong and long roots make them suitable to provide stability during the movement or tooth alignment process. To avoid problems with crowding or space in the dental arch, it is important that tooth number 11 is in the right place.

Note: Some other important information regarding tooth number 11 or the upper canine, is that it has the highest longevity rate. If given proper oral hygiene, they can remain healthy throughout a person’s lifetime.

Tooth Number 11 Respective to Adjacent Teeth

The relation between tooth 11 and 12 is that they both are adjacent teeth. One of the is Canine and the later is the 1st premolar or 1st bicupsid. While talking about the relation of tooth 11 and 21 is none but that tooth 21 is also a 1st bicupsid in the lower left quadrant adjacent to the other canine teeth which is tooth 22.

Decay of Tooth Number 11

Tooth number 11, which is canine, has a lower rate of decay if looked after with proper oral hygiene. By using fluoride toothpaste and going to proper appointments. Get a better, more nutritious diet for healthy teeth and avoid sugary and spicy foods.

Decay of Tooth 11 Root Canal

When we say “root canal decay,” we imply the rot has reached the dental pulp and requires root canal treatment. Dental decay, commonly called cavities, is a bacterial infection that destroys tooth structure.

Dental rot can spread to the dental pulp if left untreated. Dental pulp contains nerves, blood vessels, and connective tissue. When decay reaches this level, it can inflame and infect the pulp, causing toothache, sensitivity to hot and cold temperatures, swelling, and abscesses.

11th Tooth root canal treatment procedure

  • Remove the inflamed on infected pulp
  • Disinfect and clean the root canal
  • seal the root canal to prevent any furthur infection

After root canal procedure the, a dental crown is placed to give a proper look to your teeth. One more thing to note that if the root canal is not treated properly on time may lead to the tooth number 11 extraction
