Colgate Optic White Whitening Mouthwash contains 2% hydrogen peroxide that works great for whitening teeth. This may help to remove surface stains and bad breath to some extent. A mouth rinse, on the other hand, will not produce the same whitening results as an LED whitening kit or Whitestrips. Because it helps prevent new stains, whitening mouthwash is best used in conjunction with another whitening product. Let the icy fresh mint flavor refresh your breath in the morning or between meals.
