Gas for facial fillers?

I suspect that dentists who perform filler injections offer nitrous for their patients if they have significant anxiety during filler placement.  In my practice, if the patient has a great deal of anxiety I prescribe a small dose of Xanax or Valium that they can take on arrival to my office.  Prior to taking any of these anxiolytics I make certain they have a ride home from my office. 

It's totally natural for you to feel anxious before having a procedure done. Fortunately, fillers are minimally invasive and rarely require any type of sedation. If you are very anxious about having the procedure done without some type of sedation, I would recommend an oral sedative such as Ativan or Valium or Xanax. This will typically allow you to tolerate the procedure very well.

I've never heard of anybody using nitrous oxide for filler injections. If you have severe anxiety ask your doctor about prescribing a mild sedative like xanax that you can take prior to your procedure. Just remember that you will require a ride to and from your appointment if you take any medication.
