I have used the 3D crest Whitestrips a handful of times. They are by far the best over the counter product out there for whitening. They are so easy to use, simply putting them on for 30 minutes at a time. Easy to do if you have a commute or while watching TV. The results are phenomenal. Why waste hundreds of dollars on ZOOM when you can get equal results and save money?! I highly recommend anyone who wants a brighter smile to try the Crest Whitestrips!!

I mean, they are the go to! I've tried a bunch of other strips/whitening systems and I always go back to good old white strips. I do have to space them out (can't do every night) due to next day sensitivity. But I think that's just a person to person thing. Some people will get it, some won't.

[This review was collected as part of a promotion.] These stuck to my teeth very well. I didn't feel any slippage within the hour and didn't have a weird taste due to the gel escaping. The packets were easy to open. Directions were clear. I did notice a difference, but it was not a huge difference. Maybe using for another round would deliver stronger results. That said, I will be trying again!

Before I got trays professionally customized at the dentist for whitening, I used these strips. These strips are effective in what they do. I notice a difference in whitening just after one use of these strips. However, the only negative is that my teeth are SO sensitive after using these strips. Drinking or eating anything cold afterwards is quite uncomfortable. But, for the job that they advertise to do, it's a gem. 

This is probably the best whitening strips out there. These whiten my teeth within a month of using them almost everyday and my teeth were pretty yellow. Yes, they're expensive but cheaper than going to the dentist for them to bleach your teeth. Does cause sensitivity if you use too much. If that happens then I'll stop for a couple days and start back up

[This review was collected as part of a promotion.] I was impressed with the Crest 3D White Strips Professional Express — the packaging is sleek and easy to use, and the strips stay in place comfortably. They noticeably whitened my teeth in just a few uses, making them super effective and a great value for quick results. I did experience a little sensitivity, but nothing too harsh and it didn’t last long. Overall, an easy and fast way to brighten your smile!

These work well but don't get every spot on your teeth. They also only cover the front teeth, not the molars. These leave my teeth very sensitive so I try not to use them too often bc it is painful to take them off. No I don't leave them on too long, I already have sensitive teeth and gums, so these are harsh for me.

[This review was collected as part of a promotion.] Thanks Influenster, for the free Crest 3DWhitestrips.. the packaging was not great, but that may have been due to shipping. These strips worked ok, I noticed a slight difference. I dd have a slight sensitivity to it.

I try to use these at least once a month to keep my smile bright. I put it off a lot because my teeth feel very sensitive after. Also it seemed to do a much better job whitening in the beginning. The more I use it the less results I notice. Also a bit pricey.

I'm wearing these white strips as I write this review LOL. I think these white strips do a great job. They do make my teeth visibly whiter. Just make sure to not go over the time on the box you're supposed to wear them or your teeth will be more sensitive the next day.
