Novacaine Shot and Lip Swelling
Novocaine is a local anesthetic drug often referred to as procaine. It is most commonly used by dentists for tooth extraction. It is injected and placed near the branch of the nerve that serves the area where the work is going to be done. Swelling may have been a reaction to the medication or maybe the nerve was hit with the needle. If swelling occurs it is important to see your dentist and together the two of you can figure out the best course of action.
