Bottom line

The Go Smile: Smile Whitening Light System whitens teeth quickly -- in just 30 minutes -- and is relatively easy to use. It doesn't cause as much sensitivity as professional treatments, but it only produces minimal lightening. For slightly more dramatic results, try our best-reviewed pick, Crest 3D White Whitestrips Advanced Vivid (Est. $40) , which lightens teeth about three shades in two weeks.


Whitening results vary. The Go Smile: Smile Whitening Light System amps up Go Smile's patented ampoule whiteners with a handheld whitening light. The light has a detachable and washable mouthpiece so the entire family can use it, though separate ampoules are required. The system comes with 12 whitening ampoules -- enough for four full treatments.

Manufacturers say Go Smile: Smile Whitening Light System lightens teeth up to six shades, but for testers at Good Housekeeping it only lightened teeth an average of 1.6 shades. Editors say, "As with all whitening treatments, the greater the tooth discoloration, the more pronounced the results." Although most users at Amazon.com didn't notice any whitening effects, one user says her teeth were much whiter after treatment.

Ease of use

Only requires 30 minutes. Testers at Good Housekeeping like how quickly the Go Smile's light system works -- it amps up the power of the bleaching agents so that the whole process only takes 30 minutes. Editors at TeethWhiteningReviews.com agree. Some, however, didn't like having to hold the light for so long. Maggie Gallant, a beauty expert, told CBS News that the system has a few too many steps. The treatment consists of three 10-minute light-assisted sessions in which three Go Smile ampoules are applied to teeth before each session.


Reduced sensitivity. Go Smile: Smile Whitening Light System aims to mimic professional in-office light-assisted whitening for a fraction of the cost, but according to the ADA over-the-counter products aren't as safe because they aren't supervised by a dentist. Despite reports that the Go Smile system is gentler, editors at TeethWhiteningReviews.com say there is potential for tooth sensitivity because the serum is strong and three ampoules are used for one treatment.
