[This review was collected as part of a promotion.] I wanted to give this product a try and I am so glad I did! I have used emulsions twice now and my teeth are 2 sides whiter then before! And I'm a daily coffee ☕️ drinker too. I normal would use just crest white strips this product is like the next level you need!

[This review was collected as part of a promotion.] So I am totally impressed with how well the Crest WHT EMUL Light 18g/21mL 3ct actually worked. I will admit I was very skeptical at first. You do have to use it for a week straight to notice any change. Yes it is a little uncomfortable but heck you are home and it's well worth it.

[This review was collected as part of a promotion.] I like this product because you can control the whitening solution, it doesn't get all over the place, just let the solution sit. The LED light is an added boost. The only thing is the solution makes my teeth very sensitive. Other than that, I like it.

[This review was collected as part of a promotion.] Great overall product ! , I was hesitant at first to think these would make my teeth whiter , but they have , and I will be religiously using it . It’s a very simple process and the results are worth the extra steps when it comes to brushing your teeth.

[This review was collected as part of a promotion.] If your coffee stains just laugh at your whitening toothpaste like mine do and you've stayed away from other whitening products because of the sensitivity they leave your teeth with, you have got to buy this system. It's easy to apply and you have total control over how much or little you use. I would recommend using one of those devices that keeps your lips off your teeth that comes in a family board game where you have to guess what the other player is saying. It helps and I wish the kit came with something like that. You don't have to use the light, but if you do, it will help all the more. After just one session I noticed a slight difference in color on certain teeth, after a few more, I was starting to see that bright smile I haven't in years. With very little sensitivity at all and only with light usage, for me. You have got to try this if you've given up on everything else. It works!

[This review was collected as part of a promotion.] I could not be happier than I am with the crest white light. I drink coffee and have noticed over the past few years my teeth not being as white as they once we're. The crest light changed all of that. I'm more confident in my smile and really notice a difference. Very happy with this product!

[This review was collected as part of a promotion.] I am really impressed with this product. It is very easy to use, and I can really see an improvement in the whiteness of my teeth after use. I really like the light therapy and would definitely recommend it as an easy whitening solution.

[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.

[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.] Ordered this teeth whitening product in the mail to take care of some staining on my teeth from coffee and this is a great product. You can see the difference in one application. Really easy to use. Just pop in your mouth and kick back
