The Upper Left Lateral Incisor Tooth 10: Location, Function, and Care

Tooth 10 is one of the incisors, and we call it the lateral incisor. Tooth 10 is present on the upper left side of the mouth. Like all incisors, it helps a person break down food. In this way, the food becomes edible. These incisors play a very vital role in chewing food.

Tooth Number 10 Location

Tooth 10 is a lateral incisor, and if we talk about its location, it is present in the upper quadrant of the mouth. In the upward direction of the mouth, it is present on the left side.

Can you Get 10 Teeth Pulled at Once?

If we talk about the limit on the number of teeth that can be extracted at once, there is no limit. Since, during the same procedure, the extraction of many teeth is not so common, Thus, patients with severe tooth decay sometimes have only this option.

Is Tooth 10 Anterior or Posterior?

Here, the back or posterior tooth numbers are (17–21) and (28–32). So it is obvious that tooth ten is not posterior. But if we take a glance at anterior tooth numbers, these are (6–11) on the top front part and (22–17) on the lower front of the mouth. It is clear that tooth ten is an anterior tooth. Check out the chart where tooth 10 lies.

Maxillary Lateral Incisors

The pair of upper teeth that are present away from the midline of the face. Yet also away from both maxillary central incisors and both maxillary canines. These are maxillary lateral incisors.

Significance of Lateral Incisors

Tooth number ten is a lateral incisor. It will have the same importance and function as all lateral incisors. The incisors are of great significance. 

  • They play a dominant role in cutting food during mastication, also known as chewing.
  • In general, no cusps are present on the teeth. But on the maxillary lateral incisors, the talon cusps are most prominent. This happens almost only in rare conditions.

Size of Maxillary Lateral Incisors

Here we will discuss the length of the primary lateral incisors, the length of the root, and the length of the crown.

If we talk about the primary lateral incisor, its average length is 22 mm. As well, the average length of the root is 11.4mm. Moreover, if we talk about the length of the crown, its length is 11.4 mm.

Ratio of Lateral Incisors

In general, the visible width of maxillary lateral incisors is 62% of the width of central incisors. The visible width of the canine is 62% as compared to lateral incisors. Yet the proportion is the golden proportion.

Shape of Maxillary Lateral Incisors

Not all incisors, but lateral incisors, are variable teeth morphologically. Lateral incisors show reductions in their size. As well as abundant alternations in their shape. They can be cone-shaped, canine-shaped, barrel-shaped, or peg-shaped.

Average Canal Length of Lateral Incisor

If we talk about the average canal length of the lateral incisor, the average length is 22mm. These lateral incisors only have a single canal, and in general, the development of the root starts around ten years of age. We know that, in general, a maxillary central incisor is a single-rooted tooth. That’s why it contains only one canal.

Treatment of Lateral Incisors

In case of the treatment of lateral incisors. There are three treatment options available to replace the missing lateral incisors. These treatments include:

  • Canine substitution
  • A tooth-supported restoration
  • single tooth-implant

Baby Lateral Incisors Come First

In general, the first teeth that appear are the bottom front teeth, which are central incisors. These central incisors, along with the four front upper teeth that are central or lateral incisors, come behind four to eight weeks later. The lower lateral incisors will appear about a month later.

Is it Normal for Lateral Incisors to Come Before Central Incisors?

In the sequence of eruptions, the variations are visible. But if we talk about the eruption of maxillary lateral incisors before the eruption of maxillary central incisors, it is quite uncommon.

It is necessary for the parents to know that in the sequence of eruptions, variations occur, so they should contact a specialist.

Does the Lateral Incisor Fall out First?

The tooth 10 wiggles after some time and falls out because the roots of lower incisors become loose. First the upper incisors, followed by the lateral incisors. In general, the upper lateral incisors fall out first. Whereas the lower lateral incisors fall after.

Missing Lateral Incisors

A condition known as hypodontia refers to missing lateral incisors.

tooth hypodentia

In this condition, a person is congenitally born with missing teeth. In case of one of the most typical dental phenomena, right next to having extra teeth, it is common.

Lateral Incisor Missing Genetic

There is a genetic or congenital absence of one or many temporary permanent teeth. Such a condition makes reference to Anodontia. The upper lateral incisors are present among the teeth, which are congenitally missing. They are missing due to an incidence of ± 2% of the population.

Percentage of People with Missing Lateral Incisors

According to the permanent definition for the prevalence of missing maxillary lateral incisors (tooth 10) , the values range from 0.8 to 4.25% in different populations [2, 19]. In different studies, including non-syndromic tooth agencies, the possible correlation with other dental anomalies [2, 20, 21] is preferable.

Highest Incidence of Congenitally Missing Lateral Incisor

In skeletal class three malocclusion, the prevalence of missing lateral incisors was left unilateral. If we talk about the percentage, it is around 40%. 

How do I Close the Gap with Missing Lateral Incisors?

There is a question of whether wearing braces with missing tooth 10 is necessary. And the answer to the question is yes. Closing the gaps with the use of braces makes reference to canine substitution. These braces are helpful in moving the canines near the incisors to make up for the missing lateral teeth. In this way, it gives a person’s smile a more uniform look.

Do Some People not Have Lateral Incisors?

In a person, the missing lateral incisors are present from birth due to some genetic problems. Hypodontia is a condition that is linked to family history. Yet, there are some other conditions that increase a person’s risk. These risks may include low birth weight and other genetic disorders. These disorders include Down syndrome.

Tooth 10 Root Canal

In general, if we talk about root canals, they are easiest on the front teeth. We can apply the tooth 10 canal to the front teeth, it will be less painful.

Most patients have moderate symptoms. In the International Endodontic Journal. After one comparative study of 168 root canal patients, a pain level was retell. This pain level is drifting above one on a zero to ten scale.
