Do crest whitestrips really work?
Me and my 2 teens have used the crest premium. They work great. My dentist was impressed how white my teeth were. I got lots of compliments about my teeth and they asked what I was doing to get them that white. I had some sensitivity that I had to stop using them for a couple of days and then continued. That helps. The sensitivity is not permament, just a couple of days then it goes away. My daughters didnt have any trouble with sensitivity. So I guess that just depends on you. If you are cheap like me, go shop ebay. You can buy them much cheaper there.
