Didn't really find they slid off as others have mentionned. Stayed on OK for me. They do brighten up your teeth. The only complaint I had was I found I had to use them every other day because my teeth are sensitive and they were aching a bit while using the product daily. Not sure if that's a good thing or not....the instructions indicated they may bother sensitive teeth and to wait a day or two in between. All in all I would use them again as they did show some improvement. Not strikingly white but a bit better.
My wife loves these strips, they work. No messy gels to deal with. They work better than any dentist paste.
They do slide off easy but I have my own trays to fit my teeth from the dentist so I prefer them like that and they work GREAT!
this product does whiten teeth, all give it that .. however, it does not stick very well, you have to clench your teeth or keep mouth closed during treatment, otherwise they slip/slide off
What a great job,I'm verry happy with the results, no problems with the product...
I bought this item while it was on sale, and I did see some improvement after the second day. However ( maybe because I just have really sensitive teeth) my teeth would have sharp shooting pains during the 30 minutes I had them on, which makes me hesitant to try them again.
Very easy to use, though takes a bit of committment to stick to the schedule regularly, but it's for a shorter amount of time compared to some of the other products out there.
A bit expensive but does provide some improvement. Not as much as I would've liked but it's noticeable.
Works awesome! Hadn't even finished using it and you can see a difference!
Decent product, does work well if you can manage to keep them on the whole time.
However, it can get pretty messy and isn't very convenient to use.
If you have the extra money get the Professional ones for easier usage; if not these still a solid choice.
Great product, but I will not lie, it is a bit expensive, I buy it when it is on sale.
These things don't want to stay on your teeth for anything. If you so much as speak a single word with them on, they end up sliding off and you have to stick them back on again. If that wasn't bad enough, I didn't notice a difference at all after using all of them as instructed. Buy the Professional Effects strips. They stay on your teeth and actually work. These are garbage.
This product works well... I noticed a difference after the first application. I have only experience minor tooth sensitivity but I've been brushing with Sensodyne twice a day as a preventative measure (a tip from my dental hygenist).
I'm only half way thought my box of 10 strips and I'm very pleased with the results so far. I would definitely recommend Crest 3D White Whitestrips to friends. : )
A little messy, but pretty easy to use. They do whiten your teeth, without giving you that glow in the dark, 'fake' teeth look. I did the process fully once using all the applications. I then got a second package for maintenance, just doing one application as a little 'touch' up once in a while.
These are the very first whiteneing strips I have ever used and they DO work!
My teeth are much whiter and others have noticed the difference without me telling them. I have extremely sensitive teeth and after the third consecutive day, my teeth started to ache so I waited a few days before applying them again and then it was fine. I would reccomend these to my friends!
