So I thought I would mention one more thing. I had to go to the dentist yesterday. It turned out that a few of my fillings had failed and needed to be replaced. So they had to grind out 3 fillings and refill them. It took three hours..... yeah. Anyhoo it didn't hurt at all while they were doing it but today I am feeling it. The crazy part is, and I am sure this is old news, they used this new Ultraviolet curing ceramic/resin. Last time I had a filling it was a metal alloy type thing. So you can imagine when they brought this crazy light wand doo-dad up to my mouth I was kind of freaked out. Well you can guess where this is going. I am going to find some of this stuff and try it for myself. I know a few folks have already messed with this stuff (Phil Carrizzi: see photo below). Also the new 3D printer that we ordered at New Paltz works on the same principal where resin is cured using a UV light as it is being pulled out of a pool or reservoir. Cool stuff.
