Tooth 26: Number of Root Canals and Extraction

According to the Universal Numbering System, the human mouth contains 32 teeth in total, which are numbered from 1 to 32. Tooth number 26 is the second lateral incisor. Tooth 26 is a chisel-shaped tooth that erupts approximately at the age of seven to eight years. The primary function of tooth 26 is to cut food. The tooth number 26 contains such sharp edges that it cuts the food into small, chewable slices and makes it easily digestible.

Tooth number 26 is also helpful in guiding food inside the mouth and on the chewing surfaces of the molars. In some rare cases, teeth 26 is not properly shaped, and sometimes it is missing. There can be several reasons behind the abnormal shape of tooth 26, such as genetics, injury, or diseases. People can have difficulty chewing food due to the absence of tooth 26. Anyhow, for the replacement of tooth 26, a dental implant is necessary.

Tooth 26 Location in Lower Jaw

Tooth number 26 is the lower left incisor, and it is the fourth tooth from the left side in the lower jaw. Tooth numbers 25 and 26 are located next to each other. A structural diagram showing the location of tooth 26 is provided to the people.

Tooth number 26 is located directly below tooth 25, which is a central incisor. In the lower jaw, the teeth are numbered from 17 to 32, and tooth number 26 is one of these teeth. On the lower jaw, tooth number 26 is considered the most visible tooth when a person smiles. Tooth number 26 is noticeable just because it is present on the front of the mouth. Tooth number 26 contains a flat surface with sharp edges.

Eruption of Mandibular Lateral Incisors

Tooth number 26 is a mandibular lateral incisor located in the lower front jaw. The mandibular lateral incisors erupt approximately between the ages of 10 and 16 years old. Sometimes tooth number 26 erupts as early as 8 years old, and sometimes as late as 18 years old. However, the eruption of tooth number 26 is a gradual process, and it can take several months to erupt.

The crown is a structure in the human mouth that appears as a white dot on the gumline. The gum tissues push this crown forward, and within a few weeks, the tooth starts to slowly erupt. The exfoliation of the canine tooth occurs concurrently with the eruption of the mandibular lateral incisor. The space created by the loss of deciduous canine teeth is the point of eruption of permanent mandibular lateral incisors.

Missing Primary Mandibular Lateral Incisors

A condition in which two lower front teeth do not develop properly is known as missing primary mandibular lateral incisors. However, this condition occurs in very rare cases. The condition occurs for a variety of reasons. One of the main reasons is genetics, as the missing tooth is a hereditary condition if both or one of the parents have missing teeth. Due to this, the child can also have missing teeth.

The other reason behind the missing primary mandibular lateral incisors is environmental. During pregnancy, the woman is exposed to certain chemicals and radiation, which can also increase the risk of missing teeth. Systemic diseases are also a reason for the missing lateral incisors. There are some systematic diseases, such as rickets and syphilis; these diseases are the basic reason for missing teeth.

If the primary mandibular lateral incisor is missing, it can cause a gap in the smile, and the patient will have difficulty chewing food. The severity of the problem and the age of the child are the two main factors on which the treatment of missing primary mandibular lateral incisors depends. In the case of young children, the dentist will simply monitor the condition to examine the eruption of the tooth. Treatment is required even if the permanent tooth does not immediately erupt.

Length of Mandibular Lateral Incisors

If we discuss the length of the mandibular lateral incisors, it is 21.3 mm. The range of this length is 18.9 mm to 23.7 mm. The length of the crown in mandibular lateral incisors is 8.6 mm. Whereas the length of the root is 12.7 mm. The root of mandibular lateral incisors is a bit longer and thicker as compared to mandibular central incisors.

The Table below shows the average length of mandibular lateral incisors:

AspectAverage Length(MM)Range(MM)
Crown8.66.3 to 10.5
Root12.7 9.4 to 16.0
Total21.318.9 to 23.7

However, there are variations in the length of the mandibular lateral incisors depending on the individual. Even within the same individual, there are significant variations in the mandibular lateral incisors’ size and shape.

Maintaining a healthy and beautiful smile involves a combination of good oral hygiene practices, regular dental check-ups, and healthy lifestyle choices. Here are some tips to help you protect your teeth and achieve a better smile:

  • Brush Twice(daily)
  • Floss Daily
  • Limit Snacks
  • Avoid Smoking tobacco.
  • Maintain a Balanced Diet
  • Wear a MouthGuard if You Play any Sports.

Anatomy to Understand the Structure of Teeth 26

Tooth number 26 is a lateral incisor whose anatomy is based on the following structures: crown, root, pulp cavity, dentine, and enamel. The most visible part of tooth number 26 is the crown, which is present on the gumline. This part of tooth 26 is made up of the hardest substance in the body, known as enamel. The crown of teeth 26 contains cusps and bumps. Another part of the anatomy of tooth number 26 is the root, which is present below the gum line.

The root is made up of a substance that is less hard as compared to enamel. There are three roots in tooth 26’s anatomy. Inside the tooth, there is a hollow space that contains the pulp; this hollow space is known as the pulp cavity. The thin layer that makes up the bulk of the tooth is called dentine. The hard, white outer layer of the tooth is called enamel.

Surgical Extraction for Tooth Number 26

Tooth 26 is often curved in shape, which is why it is difficult to grasp with forceps. There is a sinus cavity in the mouth, and the roots of tooth 26 are sometimes close to the sinus cavity. You will find coexistence in the extraction of tooth numbers 26 and 27. The reason is that the roots of both of these teeth are interconnected. Surgical extraction can be required if tooth 26 is partially or completely buried in the gums.

There are some rare cases where tooth 26 can be extracted in segments, where the roots are removed one by one. With the help of segment extraction, the risk of complications is reduced. As part of the extraction of tooth 26, the dentist will place a bone graft in the empty socket. This will help promote faster healing.

During extraction, the tooth fracture can break, and in such a situation, further surgery can be required to remove the remaining pieces. It is challenging to heal the wound if the dentist damages the tooth bone during the extraction of the tooth. 

How Many Canals Does Tooth Number 26 have?

In tooth number 26, there are three roots, whereas the number of root canals in each root is different. In tooth number 26, the first root is known as the mesial root, and the second root is known as the distal root. The largest root in the tooth is the mesial root, which normally contains one root canal. Anyway, sometimes there are two root canals in the mesial root.

The distal root is smaller than the mesial root, and it also contains one root canal. In rare cases, there are two root canals in the distal root. The mesial root is normally wider and curved as compared to the distal root. Tooth 26 contains a very narrow and slanted root canal. So dentists can use magnification and specialized instruments to shape the teeth in a well-defined manner and clean them.

Tooth Number 26 Root Canal

Tooth number 26 is a lateral incisor and contains three roots. There is a hollow space in the tooth root that contains the tooth pulp. The tooth roots contain the pulp, which is a combination of nerves, blood vessels, and connective tissues. And the procedure that is used to treat the pulp in the root canal is known as root canal treatment. The dentist removes the infected pulp and fills it with the material that seals it off.

Let’s discuss the treatment procedure for a tooth number 26 root canal in detail. The dentist first numbs the patient’s gums in order to protect the patient from pain. A small opening is made in the top of the tooth, and files can be used to clean the infected pulp. A temporary filling is placed in the tooth in order to heal it. The root canal treatment for tooth number 26 will take a great number of appointments to complete. Yet the process of root canal treatment is quite effective because, in this process, the tooth can be saved instead of extracted.
