2-3 hrs: Usually about that long but sometimes it is quicker or slower. Get your blood pumping and it will go away faster, go for a jog...

0-4 hours: Dpends if you "drilless" dentistry, you won't be numb, short acting anesthesia can wear off as quickly as 40 min, long acting can go 4 even 6 hrs.

Anesthesiology 31 years experience
Varies: Some local anesthetics wear off within 30 minutes, while other are specifically designed to be active for up to 20 hours. It depends on the type and location of the drug. Talk to your anesthesiologist or dentist about medications that they will use.
