Mtabolism: Some people's metabolism breaks down the Lidocaine more slowly then others. Also, it depends on how much was used to numb the area. The more used usually the longer it takes to breakdown.

Maybe: Lidocaine can take hrs, carbo usually is less than 2 hrs.

It depends: On how the anesthetic was given, how much and if over the course of a long appointment. There are other local anesthetics that are designed to last longer.
