I was half kidding! I know Crest Whitestrips are bad, but sometimes I am tempted to be "bad" in order to have neon white teeth. I knew that on this forum I would be able to find several people to convince me not to use them if I got to the point where I was about to have a moment of weakness.
I'll just keep experimenting with different oils until the stains slide off from my slick teeth!
