As we all know, wisdom teeth do not play a role in our chewing function, daily activities, and the aesthetic sense as well. It is because they are located deep inside the jaw. Moreover, wisdom teeth can also cause misalignment and loss of aesthetics. Hence, what is the actual role of wisdom teeth? And when should we remove wisdom teeth?

What are wisdom teeth?


The last teeth which erupt on each side of the jaw, or the number 8 teeth are also known as wisdom teeth. These teeth tend to appear in adults, over 18 years old. Because wisdom teeth grow last, our palate does not have enough space for them to grow normally as other molars. Therefore, when they grow, it will lead to painful swelling. Without timely intervention, wisdom teeth under gum will lead to many dental diseases, such as bad breath, swollen gums, etc.

What are the benefits of wisdom teeth?

Wisdom teeth only grow in adulthood. Due to the late appearance, it must go through the process of rooting, and it takes a while for the wisdom teeth to grow from the gums. However, there are many cases where wisdom teeth grow askew and underground, causing pain and inconvenience. Therefore, wisdom teeth, also known as teeth number 8, have no benefit of aesthetics or chewing function.


Currently, many people believe that wisdom teeth have their meaning and should not be removed. They also suppose one set of teeth should have enough 32 teeth, including 4 wisdom teeth in the upper and lower jaw. However, these beliefs are completely wrong, wisdom teeth not only have no special meaning but also they cause a series of dangerous complications. First of all, it causes pain in the wisdom teeth area, and diseases such as: inflammation, swelling, etc. If there is no timely treatment and intervention, it will cause destruction of the surrounding bone, making it easy to push the remaining teeth.

When is the best time for removing wisdom teeth? 

Wisdom teeth need to be removed in case they grow in unfavorable locations, or too deep in the jawbone, which makes it difficult to clean and creates an ideal environment for bacteria to grow and increases the risk of gingivitis and tooth decay. 


Specifically, wisdom teeth need to be extracted in the following cases:

  • When wisdom teeth get complications such as cysts, recurrent infections, affecting adjacent teeth, they should also be removed to prevent complications.
  • When wisdom teeth create gaps between wisdom teeth and adjacent teeth.
  • When wisdom teeth grow in places where there are no opposing teeth to match, protruding to the opposite jaw and creating gaps among teeth, food cramming and mouth ulcers.
  • When wisdom teeth are irregularly shaped, deformed, small, causing stuffing of food with adjacent teeth, and leading to diseases for adjacent teeth in the future.
  • When wisdom teeth are the cause of a number of other systemic diseases.

However, not all wisdom teeth need to be extracted. It is possible to preserve wisdom teeth in the following cases:

  • Wisdom teeth grow straight, normal, do not get stuck with bone tissue and gums, do not cause complications. In this case, the patient needs to use dental floss and specialized brushes to clean thoroughly.
  • Patients with chronic diseases related to the heart, lungs, diabetes, etc.
  • Wisdom teeth involve important structures in the jawbone, nerves, etc.
