Why do not all wisdom teeth fall out in adults?

Dental Clinics in DHA Lahore

Third molars are also known as wisdom teeth Dental Clinics in DHA Lahore. However, there is no link between a person’s wisdom and the eruption of wisdom teeth. They are traditionally referred to as wisdom teeth because they usually appear in people over the age of 17. Furthermore, it is not necessary for all adults to have all of their wisdom teeth erupt.

Some people may have wisdom teeth Dental Clinics in DHA Lahore that have not yet erupted. These wisdom teeth have a high chance of erupting without any intervention. A dentist can judge and predict the eruption of such teeth based on clinical examination and radiographic findings.

Some people, on the other hand, may have impacted or embedded wisdom teeth. This type of wisdom tooth has lost its ability to erupt in the mouth and instead remains lodged within the jaw bone. It may necessitate surgical intervention to be removed.

Reasons for Wisdom Teeth Noneruption

Wisdom teeth are missing

Dentition in humans has evolved over time. To eat coarse food and chew raw meat, ancient humans needed more teeth. However, modern man consumes more cooked, processed, and refined foods, reducing the need for more teeth.

Because of this change in eating habits, the third molar teeth have become redundant. According to research, approximately 35% of humans will eventually stop developing wisdom teeth. Some experts predict that wisdom teeth will eventually disappear from the jawline.

Third molars that erupt late

Not all wisdom teeth erupt during adolescence. Furthermore, it is not necessary for all third molars to erupt at the same time. There have been reports of wisdom teeth erupting in adults in their late 40s or even 50s. The cause of the late eruption is still a source of debate among scientists, and it remains unexplained to this day.

There isn’t enough room in the oral cavity

One of the most common causes of an impacted tooth Dental Clinics in DHA Lahore is a lack of space in the oral cavity. The human dental arch has shrunk over time, and because the third molar is the last tooth to erupt in the oral cavity, there may not be enough space for it to do so.

A small or narrow arch is sometimes attributed to genetics. If one inherits a smaller or narrower arch or wide third molars from either parent, it may contribute to wisdom tooth non-eruption.

The tooth is angled incorrectly

The other major cause is incorrect wisdom tooth positioning within the jaw bone. The tooth may be positioned incorrectly, preventing it from erupting.

As discussed below, the causes of an impacted tooth can be divided into two categories: local and systemic.

Causes in the Community

The eruptive barrier

An adjacent second molar tooth can sometimes act as a barrier, preventing third molar teeth from erupting. In addition, a thick and dense bone covering the wisdom tooth can prevent it from erupting.

In some cases, a lack of space in the dental arch can prevent a tooth from erupting. Other causes include the presence of supernumerary (extra) teeth, which occupy the space available for wisdom teeth, retained primary teeth, in which some primary teeth do not shed away and remain intact, a non-absorbing bone covering the wisdom tooth, an abnormal position of the wisdom teeth’s tooth bud, which prevents its eruption, trauma to the wisdom teeth’s roots, and any lesion surrounding the tooth.

Systemic Root Causes

There are a number of other medical or genetic conditions that can prevent wisdom teeth from erupting.

Individuals with diseases such as rickets Teeth Scaling and Polishing in Lahore, anaemia, tuberculosis, and congenital syphilis have been reported to have impacted teeth. Some endocrine disorders, such as parathyroidism, hypothyroidism, and achondroplasia, also play a role in third molar tooth impactions. Because of these medical conditions, there is less osteoclastic activity, which does not dissolve the bone surrounding the third molar teeth.

Some hereditary disorders, such as Down syndrome and cleft palate, result in less absorption of the overlying bone and, in some cases, the loss of the eruption pathway of the third molar teeth.
