I have been using the Crest 3D whitestips now for 6 days (2 times a day) and I have seen little results. I am a smoker and thought I would try it because I want to make my teeth whiter. I will finish this product but as of now I would not recommend this product to my friends. It is expensive and does not give good results.

[This review was collected as part of a promotion.] I wanted to love these! I even made sure to take a before photo of my teeth hoping for a dramatic after pic. I really tried to use them consistently, but I know I have sensitive teeth so I started with every other night. Even that was bothering my teeth so I just fell off the wagon and can only use them sporadically. They’re easy to use and I’m sure they’re effective if you have teeth that can handle it. I’ve yet to find a brand that my teeth like.

Do you recall the old cartoons sound affect that accompanied a great big smile? Whether the smile was used to cover up a sneaky behavior or to show great pride....CHING!!! accompanied a great big and brilliantly white smile. Well, that is what 3D White Whitestrips Professional Effects has caused to replay in mind every time I confidently flash an ear to ear smile. Many people have commented on my white teeth. My son got his braces off and was a bit surprised at some of the staining.....but only until he used the strips. Then....BAM.......BANG.........BOOM.......CHING!!!!!!!! He restored his smile too!

[This review was collected as part of a promotion.] Thank you so much to Influenster and Crest for sending me this product to try in exchange for my honest review! I have used this product before and I love it so much! It truly is the only thing that really works for me. It does burn and can cause sensitivity if you use them too often or keep them on too long, so just be careful because of that. However I think this is a great value because you get so many strips in the pack for a price that it much better than professional whitening and can be used in the comfort of your own home. I do produce a lot of saliva after using, but I like to put them on before the shower so I can easily spit out the excess. They are not too comfortable but you get used to it. My only real problem with these is that keeping them on for a full hour is a long time. However, I believe that they do sell ones that you keep on for a shorter amount of time. Thank you again to Influenster for sending me this product to try!

I have 15 years working as a dentist in a pediatric setting. I use this product exclusively for myself and recommend it to children over the age of 15. I love this product and have not personally experienced sensitivity. Patients and parents love the cost!

[This review was collected as part of a promotion.] The crest whitening strips are the original whiting method I ever used and continue to be effective! The only issue I have with them is that my teeth get really sensitive but I have really sensitive teeth

For all the coffee drinkers out there, the single struggle of coffee stained teeth is too real. If you're any thing like me, you may have skipped on few cups of coffee for the sack of trying to avoid coffee stained teeth. I was literally tired of skipping out on my caffeine and decided to rejuvenate my teeth with Crest 3D White Whitestrips. Now every morning I can be alert, on my toes and have the beautiful smile to carry me through my day. Thanks Crest 3D white Whitestrips !!!

You would think theyre paying me to write this but seriously is such a great product. Ive been using them every other day already for a week and I could already tell the difference. I have 2 white stains on my front teeth (stains that have been there since I started growing my adult teeth) anyway, that little area is so white it makes the rest of my teeth look really yellow! I love to smile but its always on the back of my mind that people can notice my yellow teeth. BUT NOT ANYMORE! I smile more confidently and notice it every time I glace by a mirror or any reflection. Its great. I'm so happy with this product. Worth the buy!

[This review was collected as part of a promotion.] Crest 3DWhitestrips Rapid Smile Makeover are easy to use and stay in place thanks to their no-slip grip. They remove deep stains and let you talk or even drink water while whitening. Great for fast, convenient results. I highly recommend it to everyone.

My fiance and I used these before our wedding. I only used them twice and I still got a lot of comments about how white my teeth looked. We bought the professional effects and planned to split them, 10 days of treatment each, which made it a good value for us.
