the bottom strip is fine.it covers all the bottom teeth that can possibly be shown when you smile.

however, the strip for the top teeth only cover 6 of them!!just 6 teeth! (my teeth are normal size)
i have just completed the 14 day box with fair results, the easy method of comparison being seeing the yellow upper teeth not covered by the strips.

have the whitestrips always been so small?plenty of my teeth shown in my smile are left visibly yellow, which is kind of annoying considering the money l paid for the crest whitestrips.if l buy another box, it still just covers... six of my upper teeth.is crest skimping just recently or have their whitestrips (14 day level) always been so small?

which whitening strip brand or product covers all teeth?

Best bet go to your dentist who will make you a custom tray to fit your unique teeth, and use an at home bleaching system, for under $200 you can get nice and white on all your teeth.

That is how it has always been, just the front 6 teeth.. l suppose you could use two and go from side to side, but as general information goes.the canines (eye teeth, the pointy ones) are always a shade or so darker..that is their natural way...
