"  We&amp;#039;re always looking for a faster and easier way to whiten our teeth because let&amp;#039;s face it, there&amp;#039;s nothing like a sparkling white smile. Over the years we&amp;#039;ve seen countless products that promise to lighten teeth. While whitening toothpastes are a major part of the market, they&amp;#039;ve never proved to be miracle workers as they usually contain buffers but not chemical whitening agents. We were intrigued by Colgate&amp;#039;s new Optic White toothpaste, that contains hydrogen peroxide, the same ingredient used in whitening strips. Optic White claims that you can see results in as little as one week and all it requires you to do is switch your toothpaste. To find out if Optic White&amp;#039;s a fast track to a brighter smile, we had twenty women use it and another twenty brush with the leading brand of whitening toothpaste. Both before, and after, our week-long brush-off, we identified our panelists&amp;#039; tooth colors with a device called the Ivoclar Vivadent Chromascop Tooth Shade Guide. We found that only the two of the twenty Colgate testers experienced any tooth brightening and it was very subtle at that. However, none of the women using the control toothpaste showed any changes in tooth color.    In terms of the brushing experience, panelists had diverging opinions about Optic White. While some complained that it had a chalky texture, a medicinal taste, and/or wasn&amp;#039;t &amp;quot;minty&amp;quot; enough, others said that their mouths had never felt so clean. Fascinating how differently people can perceive the same thing! Bottom Line: Colgate Optic White isn&amp;#039;t the miracle worker we had hoped it would be. But if you don&amp;#039;t mind the way it tastes and feels, it might be worth trying...after all you might be one of the few to see subtle whitening and there&amp;#039;s nothing to lose as it&amp;#039;s not premium priced and offers all the benefits, like decay-prevention, of other toothpastes.
