The best at home whitening! I usually split the box into two separate treatment’s worth so I have more for my dollar but also not using too long to cause too much sensitivity. I usually get sensitivity to my teeth while using this about 8 hours after I finish, so I usually do at night before bed that way it never effects my eating or drinking!

[This review was collected as part of a promotion.] I have used crest white strips throughout the years, and I think the professional effects are the most effective I have ever used. I noticed a difference in the whiteness of my smile in 3 applications. I also really like that one package comes with two weeks worth of white strips. The only complaint I have is that I can only use them once every few days because they make my teeth too sensitive to heat and cold.

Everyone wants a whiter smile, and many of crest's products have given us all the tools we need to achieve that movie star smile. While I don't necessarily have the memory to recall 14 years of staining my teeth, simply due to the fact that that is more than half of my lifetime and I did not make conscious decisions to improve my oral health, it seems as though the product removes my ignorant sins against my teeth and gives me a more confident smile. Thank you, Crest, for an affordable remedy that actually works.

If you’re in a pinch and need a quick whitening this is your product! All of the different whitefish strip treatments that Crest offers are great! Been using them for as long as I can remember while trying other brands and Crest has always been superior.

I liked the results that I got from this kit. I didn’t get any sensitivity from doing the kit, which I have gotten from other whitening kits. I am a tea drinker, so a good whitening kit is a must! The only tho g I wasn’t thrilled about was the price, but it’s worth it because it worked

I was not too impressed with these whitening strips. I do not have really yellow or stained teeth, but they aren't as white as I would like them to be. After finishing my box of strips, my teeth were pretty much the same as before. My experience was not that great, but I would try them again because overall they have good reviews and my box could have been bad. 

These strips make your smile not only healthy looking but YOUNG looking too...nothing says age like off color teeth....no matter how much you spend on your wrinkle creams....NOTHING makes a more obvious, quicker difference than whiter teeth! And these strips are easy, effective and stay PUT! I love these strips and it is part of my beauty routine...a MUST.

First I was skeptical about using the product , but after I started seeing results after the first week I became obsessed !!! I bought like 3 boxes in total , I started using the product in the beginning of April now it's May 18... Now don't get me wrong it really depends on the shade of your teeth and how long the process takes .14 strips come in each box .. I don't think my teeth can get any more whiter but this product is just miraculous!!!

I recently had a root canal, which resulted in a crown. My dentist asked if I bleach my teeth? I explained I only whiten with Crest WS. He said my teeth were so white, he had to submit a special order to whiten my crown even more in order to match. He was very surprised that I've never had my teeth "professionally" bleached... THANKS CREST WS!

I've been using these since march 2015 and I inmediatley noticed my teeth to be whiter but it wasn't until I compared pictures from before and after that I realized how much whiter my teeth were. They really work and now I really have a more luminous smile. I think I'll start using two packages per year so I see even better results
