I've had tons of anesthetics over the years *has molars full of fillings*, and I'm cancer free, as far as I know. I think the cancer-risk is probably one of those things where to get it on the first shot, you have to be really high-risk or something.

Your dentist would probably know a lot about it.

Not having dental is a pain. I've got two cavities I can't do a thing about.

I symphatize! If I lived in your state, I'd totally be there for you. <3
