I had my wisdom teeth removed 2 days ago and my lip jaw and chin are still numb, how long will this last? my doctor didn't warn me about this.

Uh-oh: The anesthetic should have worn off within 8-12 hrs max, and now this suggests some problem with the mental branch of v-3 trigeminal nerve. Return to your dentist asap, as this raises a concern re a complication of the procedure. Duration of the problem could be up to 3-4 wks, but depends on what occurred.

Could be a few days : This is a possible complication. But usually the sensation of the lip and chin returns completely. It can be as soon as a few days or as long as many weeks. Discuss these issues with your doctor at the 1 week follow up appointment. Most patients do fine.

Consent: Normally most doctors don't verbally warn you about all the risks that are involved with your percedure, but you have probebly signed a consent form. In this consent form usualy a list of possible complication which includes temporary or permenant numbing of areas. In your case most likely a temporary but make sure you communicate with your doctor.

Variable: It can be temporary or permanent. You should make your doctor aware of it at your follow up appointment/.
