I will have a root canal. What anesthesia is used for a root canal?
Usually its just local anesthetic, aka a numbing shot to the area that is getting worked on
There are many different kinds of anesthesia and depending on your situation the appropriate anesthesia will be administered. Frequently used is lidocaine
There are many different anesthetics, some short acting, others long acting Some with epinephrine, and some without. It is your endodontist's choice and preference. You should really ask them. Good Luck.
