Crest 3D White Whitestrips Professional Effects is worn for 30 minutes once a day for 20 days.

Full results are typically seen following the completion of the full course of 20 whitening treatments, however many people start to see significant results halfway through the whitening treatment.

The whiteness of your teeth will vary over time depending on a number of factors, including if you smoke, how often you drink dark drinks such as red wine, tea, coffee or cola. Results can last up to 2 years with the Professional effects.

Crest Whitestrips are perfectly safe, and are approved by dentists throughout the USA. Crest White Strips contain exactly the same whitening ingredients that the expensive cosmetic dentists use.
