In brief: Reversal agent
There is now an injection that can be given at the end of an appointment that actually reverses the numbness immediately.
It is relatively expensive, and i like the fact that the numbness lingers during the immediate post treatment period. Nsaid administration also insures post injection comfort.

In brief: Average is 2 hours
To be precise, novocaine is no longer in use.
Lidocaine is most popular anesthetic used and the numbing effect lasts about 60 minutes on the tooth and about 2 hours on soft tissue like lips and tongue. Other anesthetics that dentists use may last from 45 minutes to 8 hours depending on the need and situation.
