I believe that these white strips are amazing! I use them routinely about every 6 months due to my high love of coffee :) I have been using them for years! Always get compliments on my smile. I usually lean toward the milder ones for a longer time due to my teeth sensitivity.

Hello my name is Brittney and i would like to say these whitening strips are remarkable i was worried because i don't trust bleaching as far as dental bleaching but i was amazed how these whitening strips work happy to say that my smile is a non stop in the streets and i love looking at them will definitely be keeping my smile up. Thank you, Brittney

[This review was collected as part of a promotion.] As a person that consumes large amounts of coffee and tea, keeping my teeth white has been an ongoing struggle that has prompted me to buy just about every whitening product available. Every time Crest comes out with a new Whitestrips product I give it a try.

i'm typing this review as i have the whitestrips in. ive been using them for 3 days and i already see my teeth about 3 shades whiter! they really stay in place because of the advanced seal, which is great. teeth are a little bit sensitive but not overbearing. totally recommend this product. not extremely expensive either.

Needless to say with no fanfare. Crest 3D White Whitestrips Professsional Effects are by far the most effective most whitening whitestrips on the market. They are easy to use, affordable and after you get through using them the compliments just keep coming in. People notice a difference right away. They will improve your self esteem and you will find that smile of yours again!

I love these. They have transformed my smile to noticeably whiter! People ask me all the time how my teeth are so white. All of the white strips work, but professional effects is the best. I have a lot more confidence due to this product. Thank you Crest! :)

Definitely not as effective as the product used to be. I have used Crest whitening strips for almost 15 years and always saw great results even after just 3 or 4 days of treatment. (I usually whiten my teeth only once per year). I just bought this pack of Professional Effects and have gone through the full treatment and my teeth still look slightly yellow. Clearly Crest has reduced the quality...like every other company out there today who rips people off with 'shrinkflation.' Really disappointed.

These white strips are seriously amazing! I get so many compliments on my teeth since using these. Only drawback is, if I use these every day then I have a bit of tooth sensitivity. Feels like electric shocks in the roots of my teeth, not enjoyable BUT the results are worth it!

I have tried other whitening methods and these ones are the best by far. I had the same results with dentist professional whitening that was very expensive. This are easy to apply, they stay in place and i dont get the pain like others! I never finish all the stips in the box, because they work pretty fast and i get the desired results immediately Yes, I would recommend this product to everyone.

I started using the whitestrips a few months back and loved the results. Everyone noticed the difference and gave me compliments all the time. I did have sensitivity but just went from using everyday to every other day to once a week. Once my teeth were as white as I liked it was fine to only use them once a week to maintain. My sister was a bit jealous of my results since we were always known as twins even though we are a few years apart we look so much alike. Our teeth on the other hand were now very different. I gave her just three strips to use and now she has purchased her first box. We are now both lifetime costumers. Thank you so much Crest for a great product!
