“How long does dental anesthetic last?”
I need to have my tooth extracted next week and my dentist plans to use lidocaine for the procedure. How long does it usually last?

Depending on the anesthetic used from 45 mins to 12 hrs
This really depends on you individually. How our bodies break down the anesthetic. Typically, anywhere between 1-6 hours depending on the type.
This varies from patient to patient but the typical length that I find this to last is approximately 3 hours.
Normally lidocaine injections last 2 to 4 hours. However some people respond differently. Sometimes the anesthesia lasts longer,6 to 8 hours,or less,as little as 30 minutes.
Depends from case to case, but traditionally 2-4 hours.
