I learned today at the dentist that I could have had the gas, even though I drove myself. It's apparently unlike the valium, which is what they were talking about when they said I had to have someone drive me. Unfortunately, someone was already in the gas chair, so I had to do without. Still, it went well. My hygienist is awesome and gentle and comforting, so even though I was so nervous I was sweating, she caused me no pain whatsoever, and I even let her shape one of my front teeth (it had a slightly squared edge as opposed to the rounded edges of my other teeth). It took literally a minute and it looks awesome.
I am still so glad I don't have to go back until October...
