These are amazing! My teeth appeared to by whiter after the first use which was awesome. They did feel like they were burning my teeth a little. I have sensitive teeth, so the ingredients were a little bothersome. Overall a great product.

I have been whitening my teeth on and off for 20 hrs now. I started with crest white strips I. High school, used a lot of different things, even professional whitening and Crest white strips does the job the best.

It iis simple, before appling the strip to your teeth, make sure they have been dried off with a tissue or towel then apply, The strips stick much better and that is not talked about at all,

I love using these! I get compliments daily about how white my teeth are from using them. I notice a difference after just one use. Crest 3D White Luxe Professional Effects Whitestrips - Teeth Whitening Kit

I've used these off and on for many years and have always liked them. They do a great job and my dentist even noticed. They don't harm your teeth or make them real sensitive.

We tried Crest whitening strips and the result is amazing and i recommend it to everybody who don't want to pay a lot of money for a dentist and you can see the result after finish using the strips, it's AMAZING.

love the 1 hour strips I can really tell a difference in my teeth. It can feel a bit weird on the teeth so if you are sensitive just keep that in mind

absolutely work! if daily brushing and flossing isn't keeping your teeth white, this product really will. It can be uncomfortable at first because of the band and how the product activated on your teeth, but you WILL see a difference!

It works like a charm and the results last a long time. I have used them for years. To improve? Make them cheaper and where my teeth done get sensitive.

Noticed an improvement in whitening after 2 applications. I have sensitive teeth and gums so I did have to space out applications more than what was suggested
