Tooth 9 with All its Functionality
Tooth number nine is one of the incisors and is named the central incisor. It also has great significance and is present on the upper left side of the mouth. Not only tooth nine but all incisors are essential because they are helpful in gripping food and shearing it into small particles. The first thing that people see when a person smiles are their incisors. Moreover, incisors also play a very prominent role in speech.
Surfaces of Tooth Number 9

|It is the surface of the tooth away from the midline.
|It is the surface of the tooth toward the tongue.
How Rare is Tooth Number 9?
The frequency of supernumeraries in the general population is reported to be between 0.1 and 3.8%. This is the frequency in the literature. In the case of our study, it was observed that among seventy-three thousand four hundred and eight (7348) non-syndromic patients, one hundred and fifty-six (156) patients were affected with a frequency of 2.14%.
The Function of Tooth Number 9
Being an incisor, the function of tooth number nine is to cut or shear food into smaller particles. This can make the food chewable. In this way, tooth nine helps a lot in making food easier for a person to eat.
Is Tooth Number 9 Anterior or Posterior?
In general, if we talk about the location of all teeth, then these teeth are present in the mouth in a specific order. Inside the mouth, they are present in form of two arches. These arches consist of two quadrants. According to the permanent definition, each arch contains sixteen teeth, and each quadrant contains eight teeth. Tooth 9 is present in the upper left quadrant.
Is Tooth Number 9 a Permanent Tooth?
If we talk about permanent tooth numbers, they are (7, 8, 9, 10, and 23, 24, 25, 26). It is obvious that tooth number nine is a permanent tooth. Yet, the incisors as primary teeth are named as (D, E, F, G, N, O, P, and Q).
Can Teeth 9 be Extracted at Once?
In general, there is no specific limit to the number of teeth a person can have extracted at a time. Yet, during the same procedure, the extraction of many teeth is rare. Sometimes, for patients, it is the only option in cases of severe tooth decay.
After treatments of extraction to restore your tooth 9:
Flipper for Tooth 9
If we discuss dental flippers, they are the interim of temporary teeth. It is rare that dental patients use the same dental flipper for a decade. Dental flippers are for the immediate replacement of visible teeth upon extraction. Their use is like immediate dentures. In such cases, dental implants are healing, and the flippers can be used as bone grafts. We can consider them temporary teeth.
Tooth 9 Implant
The question asked by many patients is, Can a person get dental implants on their front teeth? The answer to this question is yes. If we talk about dental implants, they are the best choice for replacing missing front teeth. If we compare dental bridges and dental implants, dental bridges need adjacent teeth. These teeth have to be ground down for dental crowns, but implants in general don’t affect other teeth at all.
The Easiest Tooth to Get a Root Canal
The root canals are easier and less painful on the front teeth. As there is less pulp in the thinner front teeth, root canals are easier to do on the front teeth. Less pulp refers to the fact that getting a root canal is not as painful. This is because, in general, local anesthesia means that a person feels almost nothing.
Is Tooth 9 a Wisdom Tooth?
If we talk about wisdom teeth, they include tooth numbers (1, 16, 17, 32).
As tooth 9 is not included in these wisdom tooth numbers, we cannot say tooth number nine is a wisdom tooth. If a person using veneers gets cosmetic dentistry, then the person wants to enhance the most visible part of teeth numbers 6-11 in the upper part of the mouth and 22-26 present in the lower part of the mouth.
Eruption Sequence of Tooth Number 9
As tooth 9 is a central incisor, the first teeth that erupt are the upper and lower central incisors. These incisors erupt, usually at the age of sixteen to twelve months. After the central incisors, the next teeth that erupt are lateral incisors. They erupt between nine and sixteen months.
Importance of Maxillary Central Incisors
The function of central maxillary incisors includes providing support for the shape and appearance of lips. It helps to pronounce the particular sounds and to bite into the food a person eats. There is a typical single cusp on every tooth, which is an incisal ridge or incisal edge.
Properties of Central Incisors
In both permanent and deciduous dentitions, central incisors are larger than lateral incisors. If we talk about the incisal edge of central incisors, it is straight. And if we talk about the incisal edge of lateral incisors, it slopes towards the distal side, with a shorter distal crown height. They also play an important role in jaw position.
Anatomy of Central Incisor Tooth
Central incisors slice into the food when a person takes a bite. They are flat and thin. The upper and lower central incisors have the same shapes but different sizes. The upper central incisors are wide teeth and are the most prominent teeth in the human mouth. The lower central incisors have small size and are narrow.
Mesial and Distal Aspects of Central Incisors
Here, the labial part of the crown contains convexity in a larger amount as compared to the maxillary central incisors. There is a rounded mesioincisal angle and a crest around the mesial outline. A cervical contour in the centre of the middle third is around the distal outline.
