The dental community knows more than ever before about the consequences of not extracting impacted wisdom teeth. If impacted wisdom teeth are not extracted, the following may occur:

Teeth Shifting: Impacted wisdom teeth may shift surrounding teeth, causing bite irregularities and pain.

Bone Loss and Jaw Expansion: Impacted wisdom teeth may play a role in bone loss and expansion of the jaw.

Congestion: Wisdom teeth may contribute to sinus congestion and headaches.

Cysts and Tumors: Impacted wisdom teeth may be a factor in the development of bone destroying tumors or cysts, including cyst formation in the surrounding gum tissue.

Gum Tissue Irritation: Gum tissue surrounding impacted wisdom teeth tends to be more susceptible to gum irritation. If wisdom teeth do not fully erupt and become crooked, it may become difficult to adequately clean the gums.

Periodontal Pockets, Cavities and Bone Loss: Difficulty cleaning gums makes it easy for debris to be lodged, creating the perfect setting for bacteria. The resulting bacteria may produce periodontal pockets, create cavities and lead to bone loss.

Changes in Orthodontia and Dentures: For children, wisdom teeth may adversely affect the results of orthodontia. For the elderly, wisdom teeth may undermine the functionality of dentures.

The Advantages of Keeping your Wisdom Teeth

Wisdom teeth have advantages as well. For example, they can provide support for a dental bridge, or fill in the space left by a missing molar. Furthermore, some scientists believe that wisdom teeth may serve as a future stem-cell source for the development of new teeth.
