Ugh! I got a sample of all the new "crest whitening expressions" toothpastes that just came out. Dammit.. I tried the Cinnamon Rush(?) one, and now I have a freakin' red ring around my mouth. I rinsed my mouth, looked up in the mirror, and almost died. See, the in-laws are due any minute, and I look like Bozo the freakin' Clown. I'm not happy about it. I dunno if it's the whitening stuff, or the tint of the toothpaste (red). ARGH!!!!!
