[This review was collected as part of a promotion.] As a coffee drinker i'm always looking for products to keep my teeth white. After using consistently with Led light I've noticed quite a change in shades. I love that I can easily apply day or night, its very simple and doesn't leave my teeth feeling sensitive.

[This review was collected as part of a promotion.] the Crest WHT EMUL light is amazing. It makes my teeth feel great and them look whiter. This will deff be my new go to for white teeth I love it. Best part is i didnt have to worry bout any bad testes in my mouth. I love it!

[This review was collected as part of a promotion.] I've used a lot of whitening products. Either they are plastic film that slide around, or they are paint-on gels that suddenly aren't around because of my saliva. I don't want to spend the money for a dentist whitening treatment though. I didn't expect much from this product. I was surprised that the paint-on gel DID stay put, and the light helped to activate it without making my teeth ache like UV light can sometimes do. And with routine use, I do see a difference! Nicely done, Crest. Impressed.

[This review was collected as part of a promotion.] The crest whitening emulsion kit comes with everything you need to achieve a white smile. It came with the emulsion, the activator light and a brush and holder. It’s very easy to apply and use. The instructions helped me out! I noticed a difference in my teeth and I’m happy with the results.

[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 greatly need help in whitening my teeth but I have sensitive teeth. Crest White Emulsions did not make my teeth feel sensitive at all. It's really easy to use and doesn't take a lot of product to notice some whitening. You just use the applicator and apply the whitening gel onto the teeth, turn on the blue light and pop it into your mouth. It times out in 3 minutes and you're done. Simple, can be done anywhere and the applicator and blue light are washable. I will need to use several times to see the deeper stains lighten but I am pleased with the overall lightening.

[This review was collected as part of a promotion.] This crest whitening emulsions with the led accelerator light is wonderful. It's super easy to use. It doesn't hurt at all. I do this before I put my make up on so I have more time to wait the 30 minutes without drinking or eating. Make sure you follow directions. But really easy peasy. Highly recommend. Love my teeth and this product really helped.

[This review was collected as part of a promotion.] I was recently looking at some old pictures and noticed my teeth looking a little yellow in some of them.This whitening kit had been amazing for an at home solution to fixing any yellowing of my teeth. The directions were precise and to the point and easy to read. The application itself is quick and easy. Absolutely would recommend to anyone searching for a whitening solution.

[This review was collected as part of a promotion.] This does the trick, it doea whiten over time. you have to be consistent. i use it every night after brushing. it doesnt take that great but its not horrible. Makes my mouth water a lot and its weird to apply because its a paste but because the mouth is wet it kinda slides everywhere. its weird to apply it to the back teeth its more for front teeth but you dont only want to whiten the front. I dont think this is something i would buy, i would prefer like the strips.

[This review was collected as part of a promotion.] I only used whitening strips before so this was completely new for me. It was easy to understand the directions and easy to use. Definitely made a difference in whiteness of my teeth. I was worried about tooth sensitivity but there really wasn't any. Definitely gonna continue to whiteness with this product.
