Smile Signal Teeth Whitener!

If you're pining for a megawatt smile, look to your peepers as a guide to your ideal shade." Your teeth and the whites of your eyes should match. Go brighter at  home with a system like Crest 3D White 2 Hour Express Whitestrips ($55, at drugstores). And don't whiten more than once or twice a year. If your chompers are lighter than the whites of your eyes, cut back on the beach.
