Time is the antidote: Most of the time dental anesthetics wear off with time. Depending on the type, concentration and amount of Epinephrine in the anesthetic will give you a clue how long it will take. Sometimes 45 minutes to several hours. There is now on the market an anesthetic reversing agent that can be injected into the same area but...It is expensive and many dentists don't have it available.

Increase blood flow: Local anesthetics usually have something in them to constrict the blood vessels near the area of action to make it last longer. If you put a warm towel near the affected area, it might increase the blood flow and take away the numbness more quickly. Exercise may also accomplish this. If you had an extraction or surgery, neither of these are a good idea.

Not much: Not much you can do. It will wear off on it's own.

Nothing: Getting the non-feeling of the Novocaine to wear off faster is often unsuccessful. If this is always the case, possibly ask your dentist to use an anesthetic that is designed to wear off faster. Still, each individual may react differently in terms of time for the Novocaine to dissipate.
