Is there an antidote to local anesthesia???
Welcome to JustAnswer, and thank you for putting your trust in me!

Different local anesthetic products have different durations of action. For example, marcaine has a very long action, whereas lidocaine without a vasopressor ingredient has a very brief duration of action. So, to a certain extent, the duration of numbness can be modulated by selection of an anesthetic with a duration of action appropriate to the length of the procedure.

An alternative suggested by your question is a medication that reverses local anesthetic-- phentolamine mesylate, marketed under the name OraVerse (see http://www.oraverse.com/). This drug allows the use of more potent anesthetics for the procedures that warrant them, and still permits termination of anesthesia at an appropriate time.

Hope this helps...
