Crest 3D Whitestrips Professional Effects were one of the products we tested in our lab while searching for the best teeth whitening kits. Our tester was shocked by her results, moving from a 20 to an 8 on the tooth shade chart before even finishing the entire kit. “I was pleasantly surprised by that change,” our tester said. “I definitely got compliments on my smile.” She called the full whitening effect from the strips “a confidence booster for sure.”
The kit includes 20 sets of whitening strips that go on for 30 minutes, once a day. While whitening strips can sometimes be a little messy and difficult to use because of their slippery consistency, our tester found that these had an almost suction-like quality that kept them stuck to teeth for secure wear.
Plus, strips are one of the whitening methods most recommended by dentists for home use. When shopping for teeth whitening solutions, you should look at the peroxide concentration and the amount of contact the product has with your teeth, explains Bianca Velayo, DMD, of Green Valley Smiles Dentistry. “Whitening strips that have a higher peroxide concentration, plus have the added benefit of increased wear interaction between the teeth and ingredients, are the most effective products,” she says.
At 30 minutes a session and 6.5% hydrogen peroxide, these strips meet Dr. Velayo’s recommendation. The kit offers full results in 20 days, with one treatment per day, but you should notice a difference in as few as three uses.
In addition to its standard 30-minute Whitestrips, the Professional Effects kit also includes two sets of the brand’s 1 Hour Express strips, which whiten teeth in just one treatment.
At 30 minutes to an hour for a treatment, our tester noted that either set is perfect for popping on while watching TV.
