[This review was collected as part of a promotion.] I have used this twice now. Just using for two times I see a noticeable difference in my teeth. I just had my teeth bonded and was looking for a good whitening kit! If you are like me and are looking.. look no further!

[This review was collected as part of a promotion.] I’ve given this some considered time before I gave this review. It does seem to be doing what it is supposed to, I feel that my teeth have become whiter since starting. I’m a heavy tea and coffee drinker and toothpaste can only do so much. So I’m pretty excited to see a bit of a change in color after just a weeks use. However, the clean up is something left to be desired, the gel does not like to come off the applicator nor the light after use. I won’t leave it on my teeth after use either because it makes me sick to my stomach.

I bought it a few weeks and when I finally decided to test it today; the LED light is not working. It came either already defective or the battery was already dead. It’s even more annoying because one can’t simply replace the battery… so, I paid more for having the light for nothing..

[This review was collected as part of a promotion.] I have used Crest for years because I love the results of their products. This whitening emulsion is quick and super easy to apply. Be sure to wipe your teeth right before applying so the product sticks well. After leaving on for 30 minutes the gel disappears. Tastes like mint and yes you can taste the peroxide but it’s not bad at all and goes away quickly. After only two applications I could tell a difference in the tooth shade especially on the lower front teeth where it meets the gum line. I drink a lot of tea throughout the day so my teeth do have stains from that and this is the first whitening product I’ve found that actually works. I recommend doing 4 rounds like the instructions suggest.

[This review was collected as part of a promotion.] My daughter just got her braces off and wanted some whitening done. We've tried plain white strips before and they've been ok..but this Crest White Emulsions kit is amazing. The gel (although in a small tube) goes a long way. Put a tiny bit on the wand and spread on your teeth. Let it sit for 30 minutes and then use the light . Boom..already whiter. She loves it and we will definitely use this kit in the future. Easy to use, and has great results in just one use ! Highly recommend

[This review was collected as part of a promotion.] I have been using this product for a few weeks and I love it! I have definitely seen results and my teeth are much whiter. I like that this kit comes with an applicator; I feel like this helps me get every nook and cranny of my teeth. With previous whitening products, I have had problems getting the edges of my teeth and close to the gums. This Crest kit definitely has helped with that. Overall I definitely recommend.

[This review was collected as part of a promotion.] I really enjoy using this whitener. I’ve used crest white strips plenty of times but I have sensitive teeth/gums, so they would get irritated quickly. This product doesn’t cause any sensitivity for me so far and I’ve already seen a noticeable difference in my teeth.

[This review was collected as part of a promotion.] I'm an avid coffee and tea aficionado which inevitably leads to some severe teeth staining. Unfortunately I also experience teeth sensitivities and gum sensitivities normally. In the past, I've tried various whitening strips as well as whitening gel trays but these methods of whitening have caused me to suffer even more very unpleasant teeth sensitivities for quite a while afterwards. I wanted whiter teeth but not at the expense of damaging my already sensitive teeth or making them even more sensitive. Crest's Whitening Emulsions with LED Accelerator Light claims to whiten teeth 100% using a combination of the Whitening Emulsions and the LED Accelerator Light. Most importantly it also claims that it causes virtually no sensitivities, which is a huge draw for me. I have to admit that the combination of the emulsion and the LED light does whiten my teeth quite well, although I am unsure whether it's by 100% even after several uses. After application of the emulsion and usage of the LED lights for 3 minutes, I felt that my teeth did gain some sensitivity, just to a slightly lesser degree than other methods. There also doesn't seem to be much product as it only comes with 18g or 0.63 oz of emulsion, which seems to be about only 7-8 applications. The instructions said to apply this 4 times a day for 4 days or to continue for 14 treatments for best results but it seems like they don't even give you the required amount of emulsion for the best results. Although I liked this product, I feel that Crest should at least give you the amount for best results per product.

[This review was collected as part of a promotion.] This is a great alternative to getting your teeth bleached at the dentist. I had that done and will never do it again. Some of the most pain ive ever been in and ive gone through some injuries. I had great results with this kit.

[This review was collected as part of a promotion.] Awesome product! I’ve tried several whitening tools and nothing had worked like this.Super easy to apply I did just my top teeth to try it out to see the difference. I noticed a huge difference. I honestly can’t believe how fast and well this product has worked for me. I did have some sensitivity it has went away after a couple of times of using this.
