[This review was collected as part of a promotion.] I tried out the Crest Whitening Emulsions Light, and was really kind of excited when I saw this. I've tried using a number of different products before, and I've had limited success with different things. The least effective would probably be the wipe on product with the little foam brush. It was hard to get good coverage, and it was hard to keep my mouth from closing around the stuff while I had to wait the time it took for the solution to work. I felt like it just was getting mushed around. Not very even coverage when it was applied that way. So I guess that would probably be my least favorite. This one is a little different- you squeeze it onto the provided wand, and then you use the LED light, and it boosts the reaction. The wand is flexible so it’s easy to slather the product onto your teeth, however it can be difficult to get coverage on the more exposed areas so you need to make sure you watch out for that. Using the blue light is a really good way to use the whitening emulsion, and it makes it stay on my teeth for 10 times longer. It helps prevent the stains from coming back so it helps keep my teeth white for a longer time. I really like the results that I got from Crest Whitening Emulsions Light.

[This review was collected as part of a promotion.] As someone who has used other whitening strips, this is one of the easier and less messy ones, however, I am not sure it’s as effective. You apply the emulsion, which is quick and easy, leave on for 27 minutes, and then apply the light for three more minutes, for a total of 30. It does not cause any sensitivity, which is a plus and very important for me.

[This review was collected as part of a promotion.] I have been using this whitening product for a few weeks and am very impressed. I have never used a whitener like this before, no trays or anything else is needed. I dry off my teeth and use the applicator to paint the whitening gel on, I really like this way of doing it because I know I am getting the gel between my teeth where they are darker. You leave it on for 30 min, which during that time, I feel like my saliva does shift the gel around a bit, then do the LED light which when done, it shuts itself off. I am noticing my teeth slowly looking whiter, it does take some time but you can do this a few times per day and I have had zero sensitivity, and I usually get those zingers with other products, so I am very happy.

[This review was collected as part of a promotion.] Starting when I was about 9/10 years old I began trying out whitening products because I had stains from medication that stained them. I am 33 years old and this is the first product outside of a dental office that has truly worked to whiten noticeably AND not cause new oral problems. I have used this system 2x in 2 days and the results are so startling, I cried. This is not a strip, a tray, or toothpaste. The gel that you apply is mildly minty and doesn’t induce a river of drool. It’s easily applied with the wand and once it’s dried, close your mouth and wait 30 minutes then apply the LED light for 3 minutes and that’s it! You don’t even wash it off (or need to) at the end. This is important because it means the gel that was absorbed continues to work through the day. MOST importantly, the gel doesn’t dehydrate your teeth or cause chalky spots to appear. It doesn’t irritate or inflame your gums if it gets there, all of which means you can use this product up to four times in ONE day. That is truly amazing and allows for whitening in a short time period. I love that Crest is a trustworthy company which allowed me to try this without much worry and it’s also very affordable compared to other products. In the last two days I’ve told everyone I’ve been with just how unbelievably amazing this stuff is and how much I love it and will continue to use it.

[This review was collected as part of a promotion.] I got this a few weeks ago. I was nervous to try it but it was very easy to use. I can pop it in and do other things while the time passes. I have seen a slight change in the color of my teeth. It doesn't hurt or cause any sensitivity. I will definitely keep using it to see how white it gets my teeth.

I bought this about a month ago and have been using it almost every single day and it’s very temporary whitening.. you really must use it multiple times each day for it to be noticeable. But the main complaint would definitely be just like the other reviews.. the gel does NOT stay on your teeth whatsoever. I had to put the gel on my teeth (dry) and keep my mouth open so my saliva didn’t rub off the gel kind of pointless. Too expensive for these type of problems especially with this brand.

[This review was collected as part of a promotion.] My wife and I have both used a lot of teeth whitening products. This one by far takes the longest but you dont use the light as long. You leave the product on your teeth for 30 minutes before activating the light for three minutes. The results are great. We both smoke and drink dark soda or tea and our smiles are a natural white. Not a fake looking white. This didn't cause any sensitivity with our teeth either. So if you don't like using the led light for long periods of time and would rather use the activator, this teeth whitening system is for you.

[This review was collected as part of a promotion.] After reading mixed reviews I was happily surprised to find this system works and it’s easy! After the very first use I could see a difference. The instructions say you can use the system multiple times a day but I bam only using it once a day due to time constraints. Each treatment I can see a difference. I’m a tea drinker and it’s as bad as coffee for staying teeth this is the perfect correction!
