How do you get rid of the numbness after a novocain (procaine) shot?

Give it time: Novocaine is a local anesthetic; it is supposed to make the area numb. Depending on your metabolism and how much was used, novocaine shots typically wear off in about 3-6 hours. Sometimes novocaine is mixed with Marcaine or another local anesthetic, and may take up to 12 hours to completely wear off. If you are worried, check with the doctor who did the procedure you were numbed up for.

Wait: It will wear off over time. I assume if you are writing it has been more than a few hours already. If this has been going on greater than 24 hours call your dentist.

OraVerse: Oraverse is a medication that can be used to reverse the effects of the soft tissue effects of local anesthesia if a patient wants to decrease the duration of the local anesthetic.
