Dental Implant Glossary Local Anesthesia Medications commonly referred to as "novocaine", although that anesthetic has not been                              in regular use for more than twenty years.  The drugs commonly used to make teeth numb are now                              lidocaine, mepivocaine, bupivocaine, etidocaine, and prilocaine.  Each has different strengths and                              weaknesses; we use each according to different indications.  The medications above also are                               mixed   with other medications, including adrenalin (epinephrine).  If you have been sensitive to                               adrenalin   in the past, please inform your dentist.  It doesn't mean that you are allergic or can't                               have local anesthetic; a non-epinephrine formula can be used successfully.   True allergy to local                               anesthetic is very rare.
