2 hours: Novocaine is the brand name of an anesthetic that is no longer used. Most likely the anesthetic you were given was lidocaine. Lidocaine is the most commonly used anesthetic in general dentistry and it wears off in about 2 hours.

1-6 hours: There is variation between individuals. On average it takes a few hours and it usually wears off gradually. It also depends on the amount of anesthetic and the formulation of the anesthetic. Depending on the formulation or dosage, the numbness can last for most of the day.
