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.
The best whitening systems feature a buffer in the gel that protects the tooth enamel from damage, are extremely effective,and can transform teeth in a single office visit. Your teeth can literally brighten up to 10 shades in about an hour. In-office whitening affects only the front eight teeth and is a great jump start for take-home whitening, which is always part of an effective whitening program. Your dentist is best qualified to handle any issues that may arise from whitening treatments, such as tooth sensitivity.
