Why do wisdom teeth need to be removed?

Dr. Mark Mackley and Dr. Erik Peet and our team at Perry Dental get this question a lot. Wisdom teeth are the last teeth to come in once young people get their adult teeth. Because they are the last teeth to break through the gums, they are also called the third molars. There are four wisdom teeth: two on each side of the top and bottom of the mouth.

There is no hard-and-fast rule that says everyone must have their wisdom teeth removed. There are certain situations in which they either cause problems directly or create a situation where there is a more significant likelihood that problems will arise eventually.

Impacted wisdom teeth

If Drs. Mackley, Esplin, and Spackman and our team say you have a soft tissue impaction, it means your wisdom tooth is covered by gum tissue that is preventing it from erupting — most likely because your mouth is too small to provide the tooth with the room it needs to emerge.

The term “partial bony impaction” means that gum tissue is covering the wisdom tooth, but part of the jaw bone is also covering it, likely because there is no room in your mouth for the tooth to erupt. You can also have a complete bony impaction, where the wisdom tooth is completely covered by gum tissue and the jawbone, which both prevent it from erupting.

The importance of removing impacted wisdom teeth

Dentists often want to remove impacted wisdom teeth because of the likelihood that they will cause problems, or because a problem already exists. One such problem is pericoronitis, an acute abscess that affects partially impacted wisdom teeth. Food, bacteria, and other mouth debris can become lodged under the gum flap that covers the wisdom tooth preventing it from erupting. Pericoronitis symptoms include pain, swelling, and the presence of an abscess.

Regular dental checkups will enable your dentist to keep an eye on your wisdom teeth, especially if they have some type of impaction. Drs. Mackley, Esplin, and Spackman and our team at Perry Dental typically recommend the removal of impacted wisdom teeth because of the likelihood of problems.
