Why Do Wisdom Teeth Need to Be Removed?

Wisdom Teeth Removal

Wisdom teeth, or third molars, are the last molars at the back of your mouth. While some people can live their lives without wisdom teeth problems, many individuals find themselves facing the decision of whether or not to remove them. This article will explore why wisdom teeth need to be removed sometimes.

Limited Space

One of the chief reasons for wisdom tooth removal is the limited space in the human jaw. Most people have enough room for 28 teeth, which includes four molars on the top and four on the bottom. 

However, when wisdom teeth begin to emerge, usually between the ages of 17 and 25, there may not be sufficient space for them. It can lead to problems such as overcrowding and misalignment of the existing teeth.

Impacted Wisdom Teeth

Impacted wisdom teeth occur when the molars don’t have enough space to fully emerge or develop properly. It can result in the teeth becoming trapped within the jawbone or gum tissue. Wisdom teeth might cause pain, swelling, and even infection. 

The real question is, do you have to get your wisdom teeth removed? Of course, yes. Removing these impacted teeth is often necessary to prevent further complications and alleviate discomfort.


Wisdom teeth might disrupt the alignment of the existing teeth. Wisdom teeth may force adjacent teeth out of position as they push through the gums, leading to crowding and misalignment. 

It can compromise the effectiveness of orthodontic treatments, such as braces, and may undo the results of previous dental work.

Infection and Gum Disease

Due to their location at the back of the mouth, it could be challenging to clean wisdom teeth. Insufficient oral hygiene can accumulate bacteria and debris around the wisdom teeth, leading to infections and gum disease. 

Impacted wisdom teeth removal can help prevent these oral health issues and promote overall dental well-being.

Cysts and Tumours

Sometimes, the wisdom tooth’s sac can fill with fluid, forming a cyst. These cysts can damage the surrounding teeth, bones, and nerves if left untreated. In rare instances, tumours may develop, requiring more extensive surgical procedures.

Early wisdom tooth removal can prevent the formation of cysts and tumours, reducing the risk of complications.

Pain and Discomfort

Wisdom teeth are often accompanied by pain and discomfort. It can be due to the pressure exerted on surrounding teeth, gums, and jawbones by the wisdom tooth cavity.

Some individuals may experience headaches, earaches, and difficulty opening their mouths fully. Wisdom tooth removal can relieve these symptoms, improving overall comfort and well-being.


While not everyone will experience issues with their wisdom teeth, those who do may find removal necessary for maintaining oral health. Limited space, impacted teeth, misalignment, infections, and the potential for cysts and tumours are all factors that may warrant the removal of wisdom teeth.
