This has been the most effective teeth whitening product I have ever used. I immediately used it after I got off my braces and my teeth look amazing. I have received so many compliments about how white my teeth are! On occasion, my teeth do get a little sensitive after using this product, but that is to be expected from any whitening product.

I loved these, i have sensitive teeth and it did not hurt like a different brand did. I got so many compliments from people because it made a noticeable change in my smile. I am a heavy soda drinker and I didn't have to change my habits and the strips still worked

These are great for a quick fix to whiten your teeth quickly. I like to use them when I have something big coming up that I need a confidence boost for. Fair warning: do not use these immediately before going out & drinking red wine - you will have black teeth! It's also tricky to figure out which white strips are the best to use because there are SO many options & the descriptions don't help differentiate them at all.

I do not recomend this product since you will have sensibility after use it.I'm not saying that in a profesional bleaching you wont have it but imagine having sensibility for 14 or 20 days.That is ridiculous.I am returning the product because it is not worth,I want my money back

I was impressed by how quickly my teeth were whitened after using this product! My teeth were very yellow the first time I started using these white strips and after 3 uses over a few months, my teeth were glowing white! I got so many compliments that I knew the results were not just my hopeful imagination. Would definitely recommend!

Crest 3-D white looks professional affects white strips are by far the best on the market! I use these once every six months and I constantly get compliments on how white my teeth are!. I will continue to purchase these over and over again and you should too! You will never be disappointed!

These are the easiest teeth whiteners I've ever used and I love that they don't really inhibit what you do. You can really wear them anytime and don't have to devote a certain time a day when you know you won't get anything done. They also pretty much work as expected!

It really does the job! Whenever I have a special event or I'm wanting to impress someone, this is my go to. It's not that expensive when you look at the per strip cost and it definitely makes a big difference in how professional you look. I'm going to purchase this again and again and again!

This is the OG right here, I don't think it gets much better for this (unless you were to buy something professional). I have used this product for a few years now. It has become an "old reliable." I recommend that anyone try this product if they are experimenting with at-home teeth whitening for the first time!

I'm 5 days into this 20 day process and I've already noticed a difference. These strips are pretty easy to apply, and they stay put. I find that it helps to dry the teeth off before applying and to lay on my back so that saliva doesn't interfere. So far I'm very impressed and I can't wait to see the results at the end of the 20 days.
