Drugs, Glorious Drugs!

To gas or not to gas...THAT is the question. Nah...not petrol, we don't have much of a choice there. I'm talking root canal here...I will shortly be undergoing my second root canal. I had one probably 6 or 7 years ago (perhaps longer). My question is do I take the nitrous oxide or not? I've always been quite prone to cavities, unfortunately, and the nitrous was always a favorite of mine growing up. I believe I also received ample doses during my last root canal. Needless to say...I am not looking forward to my trip here in less than an hour. My only hope is that they will discover I won't need another on the tooth next door and can escape with just a crown on that one. Oh please say I can! I'm thinking nitrous for sure. Somehow the thought that I endured childbirth with nary a one medication just isn't helping right now. That was almost 13 years ago and although I can certainly remember that pain...it is not quite as ominous as this lurking toothectomy! Ugh...I'll let you know tomorrow what the outcome is.
