how long does local anesthesia last?

It depends. : The duration of action of a local anesthetic is related to the choice of the specific medication and its uptake and metabolism. Some local anesthetics last longer than others. The location of the administration and whether or not a vasoconstrictor was added to slow uptake also have impact. A discussion with your doctor about expectations is appropriate.
