Is there a good way to make novacaine wear off faster?

You can't.: I'm aware of several ways to make local anesthetics last longer, but none to make it wear off faster.

Novocaine: Novocaine , or procaine, is a short acting local anesthetic. It wears off relatively quickly ( minutes to a few hours). Most patients like the fact that after a minor surgery, there is little pain after novocaine. A little patience is called for.
