Most people, including many with sensitive teeth, say they can use regular strength Crest Whitestrips without any significant problems. Others, however, and especially those with very sensitive teeth, say these strips caused pain or tingling, sometimes severe enough that they had to stop using them. If you encounter problems, Crest does offer a gentler product, Crest 3D White Whitestrips Gentle Routine (Est. $35) that gets good reviews for causing less pain. They are used once a day, 5 minutes a day, for 14 days. They don't get as much praise for noticeable whitening that the other Crest Whitestrips do, but they're a better choice if the standard formulations cause you pain.
The formula is safe for your tooth enamel and the tooth guard is a comfortable fit. Wear it for just 10 – 30 minutes per day, for up to 10 days and you will see your staining and discoloration disappear. You don’t need to wait around at the bathroom mirror either; the hands-free tooth guard design means you can treat your teeth while watching television – just wait for the timer to go off when you’re done!
