This product is pretty good. I think that the white strips made my teeth considerably wider they also made my teeth incredibly sensitive. The sensitivity went away and my teeth got a little lighter but it didn't last very long. Overall I enjoyed this product

Do you recall the old cartoons sound affect that accompanied a great big smile? Whether the smile was used to cover up a sneaky behavior or to show great pride....CHING!!! accompanied a great big and brilliantly white smile. Well, that is what 3D White Whitestrips Professional Effects has caused to replay in mind every time I confidently flash an ear to ear smile. Many people have commented on my white teeth. My son got his braces off and was a bit surprised at some of the staining.....but only until he used the strips. Then....BAM.......BANG.........BOOM.......CHING!!!!!!!! He restored his smile too!

[This review was collected as part of a promotion.] When it comes to oral health and teeth, yes, the brand is very, very important. Crest is definitely a brand I trust and have been using for years. Crest teeth whitening strips provide fast and visible results at a reasonable price, at home. It did not cause any sensitivity or negative side effects on my teeth and gums. It is the definitive solution for maintaining current whiteness or removing old stains.

These work very well but i feel that they are just very very expensive to use them as much as you would need. I think you could easily find a dupe if you don't want to pay this much but if you have sensitive teeth these caused mine to be very sensitive but very white

So these definitely work great but the using part is a bit tricky. They do not stick well to your teeth and generate a lot of spit. I highly recommend taking a towel and drying your teeth before using to aid in the stocking. But trust me they work you just have to deal with the small hassle of using them.

I bought Crest's Professional Effects Whitestrips to brighten my smile before my wedding day because I had accumulated some brown coffee stains around my front teeth. I did three days of the whitestrips and was very pleased with the results! I would recommend these whitestrips to anyone wanting to get rid of stains and brighten their smile a few shades whiter.

This is super easy to use. Doesn't hurt, it's not messy, and relatively affordable. I don't use this product often, only when I need it. It only takes about 30 minutes so I usually use this with a sheet mask since you shouldn't really speak as well. Removal doesn't hurt as well, I like to dry my teeth before applying for best results.

My teeth have always been fairly white, but I’m an avid coffee and wine drinker so they’re starting to lose that sparkle. I’ve never used whitening strips before, but thought I could use a little help getting that fresh, whitened look back. Used one set and they’re good as new & look very natural! So happy with my results. They didn’t immediately look whiter after taking them off, but they did when I woke up the next morning.

These things are amazing! Really noticeably whiter after using one box. Also great that they're the only FDA approved teeth whitening product. 30 minutes a day is very easy and you can go around without worrying about them slipping off your teeth. Would recommend to anyone

I've used the leading up to my wedding day and my smile was beautiful and white and bright. This brand is the one my dentist office sells and recommends. It's so convenient I can find it in stores so I don't have to go to the dentist every time to get it!
