Why do wisdom teeth have to be removed

Wisdom teeth generally begin growing in late adolescence. That’s why they are called “wisdom teeth” because they grow at a time when we are becoming wiser and more mature.

Although these teeth carry a symbolic meaning, their appearance can be quite problematic for some people. In many cases, they even need to be removed.

Why do wisdom teeth need to be removed? What are the reasons for this procedure? Here are some of them.

Dental cysts

Wisdom teeth form inside a shell in the jawbone. In some cases, the wisdom tooth gets stuck in this shell and is unable to pierce the jawbone. This can cause the shell to expand, which in turn can lead to the formation of cysts, lesions or sometimes even a benign tumour.

Wisdom tooth extraction may be necessary in these situations to avoid further damage to the bone and jaw tissues.


Wisdom teeth that have only partially grown in, or are “semi-impacted”, are more at risk of developing cavities.

Since they aren’t fully exposed, it’s easier for bacteria and food particles to become lodged between them and the gums. In addition, their position in the mouth makes it difficult to properly brush them on a daily basis.

These problems are best avoided by extracting a semi-impacted wisdom tooth while it is still healthy.

Gum disease

Similarly, semi-impacted wisdom teeth can also lead to the development of gum disease.

Since it is difficult to maintain the teeth properly, bacteria often tends to find its way in. This can cause a dental infection or inflammation of the gum tissue, such as pericoronitis, periodontitis or gingivitis.

Restoring occlusal stability

A dental extraction may also be appropriate if the wisdom tooth does not have an antagonist on the opposite jaw. This is because the wisdom tooth continues to grow until it is supported. Removing this tooth will restore occlusal stability.

This is why dentists often extract both wisdom teeth on the same side, even if only one of them is problematic.
