Go Smile Advanced Formula B1
We've all seen commercials for Crest Whitestrips and the like, but having one of those things in your mouth for the recommended time is not only uncomfortable, it's a little gross. We've been trying out the Go Smile Advanced Formula B1 ($90), and it performs well without the inconvenience of strips. Professionally formulated by Jonathan B. Levine, D.M.D., the formula comes in little portable bottles with brush-tip ends so
you can customize your whitening and do
it on the go. Plus, it'll make your teeth
between 4-10 shades whiter in just seven
days, perfect for getting your teeth in
shape before the holidays.
