Can you have a beer after receiving dental anesthetic at dentist?

As long as you can : Drink after the local anesthesia, yes. Wait until the locall anesthesia and numbness is gone. Most dentist used local anesthesia only. If a stronger sedative given wait 24hrs.

Guidelines are: Strict on this question. Your dental surgeon will have provided you with appropriate wait-times for consuming anything having sedative properties on top of the anesthesia you've already had. If your procedure lasted longer, the wait times will be longer..If your body is compromised vis-a-vis kidney/liver function or chronic disease the wait times will be longer still. Clear up with him/her, please.
