Supersmile Professional Whitening System is gentle on teeth, doesn't cause sensitivity and is as easy to use as a toothbrush. Reviewers also like that it isn't messy and that it doesn't require a big investment of time. On the other hand, it doesn't produce as dramatic results as other whiteners. If you prefer a stronger teeth whitener, reviewers say Crest 3D White Whitestrips Advanced Vivid (*Est. $40) is an excellent over-the-counter option, but it isn't as gentle.
Subtle whitening. Like all over-the-counter teeth whiteners, results vary with the Supersmile Professional Whitening System. Testers at TotalBeauty.com noticed results within a day and overall whitening of about 3.5 shades over the course of treatment. Several reviewers at TotalBeauty.com, Amazon.com and MakeupAlley.com say the formula works very well. One reviewer at MakeupAlley.com says, "After using this for one week, I just can't get over how the yellowish stains have disappeared."
Others, however, aren't so impressed. One user at TotalBeauty.com says, "I saw no whitening at all, but my teeth are very white anyway." As with all teeth-whitening products, results are likely to be more pronounced on heavily stained teeth. That being said, Supersmile is best used on lightly stained teeth. Several reviewers said it's ideal for surface stains and touch-ups between more powerful whitening treatments. One user at TeethWhiteningReviews.com explains, "I think because most of my discoloration was superficial staining, this product worked extremely well for me." Editors at the site agree. They explain that while the formula works, "do not expect any dramatic results with this product."
As easy as brushing your teeth. Reviewers like the simplicity of the Supersmile Professional Whitening System because it doesn't require any extra steps beyond brushing your teeth twice a day. One user at MakeupAlley.com says, "A big plus is the ease of use -- since you have to brush two times a day anyway, this doesn't take up additional time or hassle." Reviewers also say it's less messy than whitening trays and strips.
Little to no sensitivity. Although Supersmile doesn't earn the ADA seal of approval -- no over-the-counter whitening system does -- it's safe for use on healthy teeth. Experts say those with cavities and/or gum disease should avoid all whitening products which can cause further damage and extreme sensitivity and pain. That being said, most reviewers say they experience zero sensitivity and discomfort using Supersmile's whitening formula. One tester at TotalBeauty.com explains that the whitener didn't cause any sensitivity for her even though most do.
