[This review was collected as part of a promotion.] I have noticed some brightening using it daily. It doesn't sensetize my teeth like the strips do. My problem is that it says to apply and leave for 30 min, but it lasts barely 10 at the most being super careful. I do apply it on dry teeth but it doesn't help much.

[This review was collected as part of a promotion.] I am a heavy coffee drinker and my teeth show it. I was looking for a whiting product that would help to brighten my smile. I chose Crest Whiting Emulsions with a LED accelerator light. Application was a bit of a challenge as you have to try to dry off your teeth before application in order for the paste to stick to your teeth. The paste is very waxy and slides off if your teeth are not dry enough. Then you have to be quick to place the LED mouthpiece on before saliva accumulates. I also did not find that this product whitened my teeth much. Needless to say I was disappointed with this product.

[This review was collected as part of a promotion.] I have been using this product for a couple of weeks and are delighted with the results. It has whitened my teeth several shades. It is easy to use and provides everything needed including the accelerator light. I love the look of my teeth and have had people ask it I had them lightened by a dentist! YEA! Great product that I will continue to use to maintain my smile at it's brightest!

[This review was collected as part of a promotion.] This tooth whitening product doesn’t work very well and is quite annoying to use. The gel doesn’t stay on your teeth so you end up with a mouthful of the stuff, and spitting it out seems counterproductive since then nothing is on your teeth to whiten them. I tried drying my teeth as recommended in the instructions but that didn’t work at all. It’s tough to say if it simply doesn’t whiten or if it wasn’t actually on my teeth long enough to do what it’s supposed to, but either way my teeth are the same color.

[This review was collected as part of a promotion.] I brought the Crest White Emul Light about a month ago and absolutely love it. I’ve also noticed a big different in my smile. Crest has always been a reliable brand though my tooth care odyssey....I’m glad they continue to be consistent.

[This review was collected as part of a promotion.] The Crest WHT EMUL Light 18g/21mL 3ct is very simple to apply and use. I used this twice a day for a few weeks and I really noticed that my teeth are whiter. There is no sensitivity with using the gel and the light. Application was easy, just spread the gel and let sit on your teeth for a few minutes, insert the mouthpiece for a little while and then get ready for the final dazzle dazzle!

[This review was collected as part of a promotion.] I was really curious to see if this product actually worked. I was pleasantly surprised! The kit was easy to use and it wasn't messy. I was glad that it didn't cause the sensitivity that I thought it would as well. Definitely worth trying.

[This review was collected as part of a promotion.] This whitening set comes with a brush, whitening gel and the led light. The gel made my mouth feel fresh right away. I felt that thirty minutes plus an additional three minutes to use the led afterwords was too long to have to use the product especially if I am doing it multiple times a day. I noticed an instant whitening just from the gel and a little more whitening after using the led light. I felt that my teeth were very sensitive even after the first use. The led light has a timer which I thought was handy so that I didn’t have to pay attention to how long I had been using it. Overall I think this is a fun way to whiten my teeth.

[This review was collected as part of a promotion.] Spoiler alert! Most babies get jaundice after they are born; I had it before I was born. What that meant was when my permanent teeth came in, they had a yellow tint. I've been trying to find a product that could remove the color without removing the enamel, and although my Mother had me using Crest toothpaste since I was a child, nothing helped. I have not used Crest WHT EMUL Light long enough yet to see a major improvement, but I do see a little, and my wife noticed it, too. I will continue to use it from now on. If it can improve my yellow(ish) teeth, it will surely improve yours..

[This review was collected as part of a promotion.] Wow, I’m amazed by the results I received from the crest teeth whitening and light. I’m beyond thrilled with the results. It’s very simple to use and just after the first use you see results. I used this for a week and my teeth have been the whitest they have ever been. I’m in love with this product. It’s a lot easier than the strips.
