Question about Crest White Strips??? HELP?
ok im gonna use them soon....
when it whitens your teeth, does your teeth actually stay white (literally stay white), or does it only work for a period of time?
thanks
Answers:
Crest White Strips will whiten your teeth up to three shades whiter. It's true; I use them. They will stay white over a period of time until food and drinks dull them again. Best thing to do is the first 14 days then once a week to keep them white. They really do work!
