These are amazing I bought a pack of these and I love them I also let my sibling try it and now she always uses them and her teeth are cleaned and nice supper good and great way to keep teeth clean

Love crest white strips! They really do make my teeth noticeably whiter after one use. Plus they are super easy to add into your morning or night routine!

Whenever I use them, I notice a difference after one use. Sometimes I experience a bit of tooth sensitivity but then I limit my use. But I love this product and use it frequently.

I use crest 3-D white strips probably every other week they're the best ever it works better than professional dental whitening and I'd prefer to use this over any other whitening agent and this is coming from a dental assistant

I've these whitening strips, I see results the next day. Be careful when using for sensitive teeth as they can leave your teeth sensitive to things like sugar and hot/cold items.

I love to have a bright smile. These strips make it so easy to do at home. Lately I have struggled with sensitivity to my teeth. These do not worsen that feeling.

I've used these and also recommended them to my patients. You will see significant results within 1-3 times of using them. I now only have to use them every once in a while, usually for special occasions. =)

For a product that you can get without going to the dentist, crest is great. Very effective depending on how much you put it on. But if you leave it on to long or use it too much it does make my teeth sensitive

The best teeth whitening strips I have ever used. After just one use I could see a visible difference, and after a couple of uses others could see a difference as well. I wouldn't use any other strips after using these!

I like these but kinda pricey for me. Does really work and I have gotten compliments from others on my teeth. Haven't used them in awhile,time to get more.
