Is it safe to take a sleeping pill the night before wisdom teeth extraction?

Maybe: If you have been prescribed it, probably. However, you should have someone drive you to the office and back and make sure you advise your dentist as soon as you get there. Better yet, call your dentist now just to confirm that it is alright to do that. He\she is the one knowledgeable about your medical conditions and responsible for your care, not we as doctors on this site.

Probably ok: Check with your oral surgeon. They must know the medications in your system. Als, be sure someone can wake you for your appt. And drive you both ways.

If needed: I would let your oral surgeon know at your consultation prior to your appointment to be on the safe side.
