1-Best White Strips: Crest 3D White White Strips with Light
The introduction of a portable blue light system that penetrates the enamel to target stains gives trusted Crest white strips a big improvement in this whitening kit. The whitening procedure begins with a 60-minute application of the flexible whitening strip, which requires a small dose of hydrogen peroxide to softly whiten your teeth. The blue light is then used for 10 minutes after the strip to improve the whitening results. After 10 sessions, the teeth will not only be slightly whiter, but the results will last for the next 36 months.
