No home teeth whitening product gets better reviews than Crest 3D Whitestrips -- and the best of the best, reviewers say, is the Professional Effects series. While the claim that it removes 14 years of stains may be a bit of hyperbole, the fact is that you will get noticeably whiter teeth if you use these gel strips.
These methods can include: 1  Toothpastes: These products strictly whiten and will not bleach your teeth. 2  Gel: Whitening gel can offer comparable results to strips. 3  Rinses: Whitening mouthwash contains small amounts of peroxide.  Pre-made whitening trays: Store bought whitening trays often fit uncomfortably.
