Next day whitening results! These work great! You see instant results the next day after wearing. I used to use this product once a month. Worked great, good results! So white!

these can be a little pricey but in my opinion they are definitely worth it, they do whiten my teeth without the extra work of having to do the whitening strips. but if you want better result's definitely do the whitening strips also!

This helps make my teeth really nice and white. I do it about twice a year. The downside is that it makes my teeth very sensitive and can hurt. I have to take Advil before using and can never keep them on for the whole amount of time

these work great! i used an entire box and noticed a huge difference in my teeth! they look so much better and gave me amazing results. i used 3 per week. on the more expensive side but worth it. id buy it again!

I put these on two years ago when I got my braces off and have not needed to put them on since. My teeth are so so so white and they got rid of all the yellow. Love this product so so so much.

Since using these products, my teeth have definitely seen improvement. I have sensitive teeth but these really don't bother them and produce noticeable differences!

I already use the toothpaste and mouthwash to maintain the whites of my teeth but when I go on vacations or during the holidays when a lot of photos gonna be taken. I use this to reinsure my teeth won't be a problem

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 used the 3D professional whitening strips and I saw amazing results, look coffee stains off my teeth. I couldnt be more happy- This product does work and Im a huge fan of the Crest brand.

I like the whitening strips but they also make my teeth feel super sensitive for a few days after I have whitened them. Other than that, they do give promising results.
