Med allergy: If you have not yet, it is unlikely. HOWEVER, we can go for years sometimes without an allergic reaction to something and then for some reason we become allergic. Be sure your dental provider is aware of your allergy and is ready to treat for any allergic reaction.

Local Anes Allergy: It is always possible to develop an allergy but the likelihood is extremely small. I have never personally heard or seen a patient allergic to Carbocaine. You can always discuss this with an Allergist and be tested first by small subcutaneous injection prior to procedure.
