The drug injected around the sensory nerves for the involved teeth and then interrupts conduction in the nerve.
I'm assuming you are referring to the local anesthetic the dentist injects to numb to area. Local anesthetics work by blocking sodium channels on the nerve to "turn off" the nerve so that pain messages don't reach the brain from that nerve. This is why the area has no feeling temporarily. Typically the numbness can last anywhere from an hour up to 4 hours.
Dental anesthesia is local. Numbness of the area. Maybe dizzines.
