After completing all 20 treatments, there was little to no difference in my teeth. i couldnt even tell i had even used them. i like the classic white strips but they are never on the shelves. Bring them back. I completly wasted my money on something that didnt even work.

I used the product 3D Crest Whitening Stripes a few months ago so I could have the whitest smile at prom. Within a week or two, I was more than happy with the results! All my friends were complimenting how white my teeth were and it gave me the biggest confidence boost ever. I've always wanted a beautiful white smile! To keep up with the wonderful whiteness, I use 3D Crest Whitening Toothpaste that tastes better than toothpaste should taste. It's honestly the best product I've ever used to keep my teeth clean and white. I plan on using the whitening stripes again this winter because I just LOVE having a perfect white smile! It's fast, easy to use, and 100% the best decision I've ever made.

I used the strips on my teeth and they were super white. Everyone that I encountered on campus said that my smile was gorgeous with my white teeth. I have only used this product twice within a seven-month span and my teeth are still white. So I would recommend everyone to use it! :)

Teeth nice and bright

Would not recommend. The product squished out the sides and tastes like mushy peroxide. It left my teeth feeling very sensitive. I didn’t notice any difference in the color of my teeth.

Love these strips but I would advise only using them as directed. If I leave them on too long I get pretty bad sensitivity but they do whiten. Would recommend if you need a quick turnaround! Will be using before my wedding in September.

Love this so much. Dont leave it on your teeth longer than reccommended, and dont do the full time until after a few times because it can make your teeth hurt. It works very well and I use it every week!

This brand is the only brand that I have found to actually make a difference. Usually after 2-3 times I can already see my teeth so much whiter than they were before.

I love these whitening strips because they make my smile look so much better and brighter! I’ve used this product multiple times and it’s amazing and very effective! I am always satisfied with these results!

It does a really good job at whitening, it works for a fairly long time. My teeth are pretty sensitive, and it definitely rises the sensitivity, which is expected
