With all those Halloween vampire costumes, thoughts easily go to fabulous fangs. Less simple is finding a teeth whitening solution that really works, without hurting even the most sensitive gums. We've tested a variety of whitening kits, strips, pens, brushes, wraps and pastes. The best so far, for deep cleaning is the new Watts Whitening Kit, for a really amped up cleaner (this is not your dad's toothpaste) we found Supersmile, touch ups on the go are provided by the convenient Brite Smile Teeth Whitening Pen, the Philips Sonic Toothbrush will put a smile on your dentist's dial, and for humble toothpaste we like Elgydium.
