Can vary: Depends on the area as well as how the anesthesia was given..Cob be as less as 45 min to as long as 6 to 8 hours.Sometimes anesthesia is given as infiltration ...Sometimes as nerve block which can take longer..Especially for back molars..Also depends on location as well as course of the nerve..
