[This review was collected as part of a promotion.] I am a big coffee drinker and I noticed that over the years my teeth were starting to show some color that I wasn't really pleased about. I tried various whitening tooth pastes and the results weren't even noticeable. Did my teeth feel clean yes, but the yellowish color was still very visible. So I decided to give this a try, I was hoping that the combination of the paste and light would do the trick. The product was very straight forward and easy to use. I followed the directions and used it for 30 seconds for a week. I really wasn't expecting much but Wow! the results were absolutely better than expected. I would say the color was at least a shade and half better than what I started with. My smile is nice and bright and even my complimented me on how white my teeth were.

[This review was collected as part of a promotion.] I just starting using this and so far so good. I can't wait to see if it really gets my teeth white. I hope it does because I just did invisalign and they are yellower than ever before. I didn't have any sensitivty either

[This review was collected as part of a promotion.] I use this twice a day. I. A smoker so my teeth are kinda yellowish. The paste itself is easy to apply then you use the light for 30 minutes. I have noticed a difference after a few days my teeth have started to get whiter than before overall a great product

[This review was collected as part of a promotion.] So my mom works for a dentist, and I work there on occasion. So I have had my teeth whitened on many occasions and tried many different things. This has to be applied to dry teeth which is kind of hard to do on your own, but not impossible. so I applied it's It did not stay on as well as it should have. but also I should have stayed sitting down the whole time and not moved around. Like if your at the dentist. Next , it doesn't not have a horrible taste. A refreshing minty taste, not bad at all! It also did not make my teeth as sensitive as teeth whitening from the dental office. I'm trying to figure out if that is a good thing or a bad thing?? Does that mean it doesn't really work??? I did not notice much of a difference.

[This review was collected as part of a promotion.] I really like this whitening system. I didn't realize before I used it though that you kept it on for 30 minutes before using the light. It was not a big deal, as it has been with other kinds in the past because this whitener feels sort of minty & cool. It does not feel weird on the teeth at all & doesn't fall off or feel gritty. My mouth watered a little in the beginning but that was it. It most definitely works very well. You don't have to use much either so the tube will last quite some time if you use it sparingly. I think this is my new fav whitening system.

[This review was collected as part of a promotion.] Crest has a ok product. I got this a month ago and I really haven’t noticed any change to the whiteness of my teeth. I’ve always been a Colgate user but thought I’d give it a try. I’ve gone back to Colgate and that’s where I’ll stay

[This review was collected as part of a promotion.] This is a great teeth whitening treatment product! I was so excited to try this when I saw it! It definitely did not disappoint! And it is really easy to use. I definitely recommend this product for people who whiten their teeth on a regular basis.

[This review was collected as part of a promotion.] I'm so glad I got this kit, OMG is all I can say because as a daily coffee drinker I knew my teeth weren't as white they used to be, but after using the Crest White Emulsions for a week and a half I see a big change in my smile, my teeth are much brighter and whiter. I'm in love with this kit I've told everyone about it. I hope Crest never stops making this kit because its better than anything else I've ever tried, its fast and didn't make my teeth hurt or feel sensitive. I definitely recommend it.

[This review was collected as part of a promotion.] This teeth whitening kit is very time consuming, therefore I would not recommend this product. The kit contains a tube of leave on teeth whitening treatment, a wand to apply treatment, the LED light and a stand to store on. You are to squeeze the treatment on this small, harder rubber-tipped wand and apply the treatment to your teeth, liberally. You allow that to sit on your teeth and can use the LED light to help accelerate the whitening process. You can apply the treatment up to four times per day. Overall, the process takes 20-30 minutes. I also think its inconvenient to hold the LED light in your mouth for a few minutes. I would not recommend this product as it is time consuming and inconvenient to whitening with the LED. I also did not use it consistently enough to see any remarkable results.

[This review was collected as part of a promotion.] Very surprised and happy with the results this Crest - Crest WHT EMUL Light 18g/21mL 3ct delivered, and the best part is there are no sensitivity issues with my teeth. You will see results even from the very first time you apply the paste, and the LED light adds an extra boost to even whitened your teeth even more. Highly recommend. When it comes to value, you can spend hundreds in products that promise to deliver and they don't, on the other hand, this Crest - Crest WHT EMUL Light 18g/21mL 3ct is very affordable when compared to other products in the market and the best part is that it delivers and gives you the results you are looking for.
