How long does it take for numbness to go away after oral surgery/wisdom

Welcome to JustAnswer, and thank you for putting your trust in me!

Persistent numbness following extraction of lower wisdom teeth is a known risk. The severity and duration of the sensory deficits is highly variable, and may run as little as a day or two, or as long as six months. Any sensory impairment that persists beyond six months of the injury is usually considered permanent, although continued improvement can occur outside this time limit. The improvement in your symptoms is evidence that resolution of numbness will eventually be complete, but the actual outcome cannot be predicted with certainty.

There are no measures that are known to accelerate or improve the likelihood of nerve healing. Although some surgeons recommend a short course of corticosteroid therapy immediately after nerve injury, this strategy is controversial. In rare cases, nerves that have been permanently impaired can be surgically grafted by an oral surgeon or neurosurgeon, but the benefits of this procedure are inconsistent.

Even in those cases where sensory impairment persists, most patients accommodate well to the deficit, and become mostly consciously unaware of its presence in most functional activities.

Hope this helps...
