Pearly Whites

I'm trying that Crest Night Effects teeth whitener for the first time tonight. I've done the strips before, but I don't care what they say, they slide all over my teeth and I end up having pools of saliva in my mouth. I don't think this paint on stuff is much better. I think I only got about 1/16 of it on my teeth. And what I did get on feels like when I got my braces off and they had taken the brackets off but hadn't polished off the glue yet. Caked, hard stuff on my teeth. Oh the price we pay for beauty.
