Do Colgate White Strips Work?

If you want to know the truth, yes, Crest Whitestrips do work. They can make your teeth look whiter because of a gel that is spread along the strip and placed onto the surface of your teeth. This substance contains hydrogen peroxide or carbamide peroxide and works to penetrate the tooth enamel to remove stains.

How long does it take for Colgate whitening strips to work?

Your teeth should begin to look whiter within a few days of using the strips and the results should last at least 4 months.

Do whitening strips really work?

The short answer is yes. Teeth whitening strips can whiten your teeth by a shade or two and can act in as little as a few days. But home products aren't usually as effective as in-office dental whitening techniques. They also come with some risks such as increased tooth sensitivity and gum irritation.
