More annoying than other Crest white strips.
These white strips are quite different from any of the previous versions of Crest strips I've tried. They're stiff, and thus less malleable. They don't fold over your teeth easily. Stretching them a bit helps a little. You leave them on for an hour and they seem to fuse to your teeth. Very difficult to remove. They seem to work more slowly than the other strips, but perhaps they are deep cleaning. My teeth are whiter, yes. As I don't drink wine or coffee, my teeth seem to reach their maximum whiteness with the others after 4 treatments. I'm at 5 now with these and they seem whiter but not in the usual glistening way. Maybe their chemical is stronger and reaches deeper, but I don't know if that's great for the surface of the teeth. I wouldn't buy these again, but we'll see if I feel that way for 18 months, which is how long they're supposed to last. The others last less than a year. I really don't enjoy the scary sensation of "what if" as I try to pry them off my teeth. So far it's worked. :)Read full review
