[This review was collected as part of a promotion.] I really like this Crest Whitening Emulsions teeth whitening kit with the light. It’s so easy to apply with the wand. Then you turn the light on to boost the whitening. It lasts about 3 minutes. They recommend not eating or drinking for 30 minutes after applying. I could tell a big difference after 3 applications. The best part is I haven’t experienced any sensitivity at all. I definitely recommend this product.

[This review was collected as part of a promotion.] Was bummed at first when they weren’t sending it out, then last night I got a nice surprise at my door! Used right away, super easy to use and nice! Didn’t Irritate my gums like regular teeth whitening kits. Noticed a difference after one use. Would definitely recommend!

[This review was collected as part of a promotion.] This system is so easy to use. I have only done this 4 times and I am already seeing a difference. I love how there is no crazy aftertaste, there is a light mint and almost cooling taste which is really nice. Systems I have tried in the past did not taste good and were very uncomfortable to use. So far I am loving using this.

[This review was collected as part of a promotion.] Easy to use! I was a little wary of the light itself, but it didn’t make my teeth sensitive at all. It’s a little messy with the gel but you only keep the light on for a few minutes so it doesn’t get too bad. I did notice a little bit of whitening, but unfortunately not much.

[This review was collected as part of a promotion.] I tried this product and was happy with the change in color of my stained teeth, but did not think it lived up to the promise of less tooth sensitivity. This may just be my extra sensitive teeth, but it was noticeable after each use.

[This review was collected as part of a promotion.] I wanted to test out this whitening gel and light because whitening strips do nothing for me. I was surprised to see that my teeth looked whiter after after two uses! The directions say you can use up to 4 times a day but I have only tried once a day at night before bed. The gel feels very gentle on my teeth and does not burn or taste bad. The light is comfortable to place in my mouth and turns off automatically when done. Looking forward to seeing how white I can get my teeth!

[This review was collected as part of a promotion.] I really love how they thought of everything, the package comes with everything you need, the application tool a stand and the LED light to make the whitening process faster. It really works, I really love the ease of use and the results are amazing. Also, I have tried others and they often hurt but this one is not painful at all.

[This review was collected as part of a promotion.] Oh my goodness! I can definitely see a difference! I’ve just started using this amazing product! And let me say this. I am a heavy smoker, yes I know. I also drink coffee for half of the day every day! I don’t tend to drink tea anymore, but of course my teeth are not the whitest! Now when I say I see a difference I can see my yellow isn’t so yellow anymore! I have been using product once a day every day. I’ve only had about a week. And I do see change! I absolutely love it! I’m so thankful this product was made! And I have to go now so I can go whiten my teeth!!

[This review was collected as part of a promotion.] Crest Whitening Emulsions with LED accelerator light works fantastic. I am a former smoker and a coffee achiever so my teeth were fairly stained. I've been using this for about 2 weeks and what a difference it made. My teeth are so much whiter than they were and unlike other whiteners I've tried it doesn't cause my teeth or gums to be sensitive.

[This review was collected as part of a promotion.] I have been looking for a solution to my cigarette - stained teeth and have found one. This Crest Whitening Emulsions works. You just squeeze some of the gel onto the brush and apply to your teeth. I love that you just leave it on and it works while not even noticing it is there. No need to rinse it off. And no sensitivity issues. Crest also includes an LED accelerator light that you hold against your teeth for three minutes. It is supposed to be used thirty minutes after applying the gel. It aids in the whitening process and is lightweight and painless. Overall, this is another great product from Crest. It is a nice compliment to their toothpastes and is giving me a nicer smile. Highly recommended.
