I used this product all the time! I don't anymore because it started making my teeth weak and extremely sensitive to cold and hot things I ate or drank

I have very sensitive teeth and these are one of the whitening strips that don't hurt my teeth! I've used them for over a year and my teeth continue to stay white.

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

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.

Favorite whitening brand for at home whitening! I feel like even after one use I see a difference in my smile. I really like the crest 3D white strips because they also don't leave my teeth feeling sensitive!

I find if used consistently, this product gives your results. I use these strips every 4-6 months to whiten my teeth. I have used these strips several times and after trying other products, i find this is the best one on the market.

I've tried many whitening products and this is by the far the best. It made my smile bright white.I'm so happy with the results. I will always buy this product!

Best white strips I've ever tried! I used to use a whitening system from my dentist office, but this is much more affordable and has better results. I noticed a difference almost immediately.

As much as I love crests other teeth whitening products. This one let me down. I didn't seem to think these helped improve my smile. I used bought one box and haven't bought since. Overall I didn't care for this product.

I used to really like these when I was younger but they have made me teeth super sensitive. I have never had sensitive teeth before. & whenever I use this product I get a sharp painful shock
