Depending on the type and amount of local anesthetic used, numbness can last for up to 4-6 hrs. Also, lower nerve blocks have a tendency to feel number for longer periods of time than do upper nerve blocks. Dr.G.
Usually 2 to 4 hours.
If you have a local anesthetic you will be numb from 2 - 6 hours depending upon the exact local anesthetic being used. If you are going to sleep with a general anesthetic or conscious sedation you should be prepared to have a driver with you to take you home because you will be groggy for a few hours after you wake up.
