[This review was collected as part of a promotion.] I have super sensitive teeth and was super excited to try this as it promises to not affect sensitivity. Easy to use and also for a tip, blot your teeth dry before applying with brush as it helps it stick to your teeth perfectly! It definitely took away surface stains after the second time use. It did not once give me any problems or pain with my teeth where as other products like the whitening strips have done and made me instantly regret my decision. I would recommend to anyone wanting to whiten their teeth and maybe has a short time frame. This is to simple not to use. 10 out of 10 for me!

[This review was collected as part of a promotion.] My teeth look great, I have never used a whitening process before and they look the best they have in my life. In the last 3 weeks I have lifted about 3 shades whiter than when I started. The waterproof light is great for giving it a big whitening boost and it so easy to use while getting ready for the day, no need to set time out just to whiten your teeth. The applicator is great because the gel is very sticky and takes a bit to get off your hands. I’m super happy with my new whiter smile and how easy the process was.

[This review was collected as part of a promotion.] I've never been a fan of the white strips. Although white strips work well, I hate the way they taste and they make my teeth so sensitive afterwards. I am so glad I found this new crest product. It was so easy to use and I really do think that the LED feature makes your teeth whiter than the crest white strips. I definitely recommend.

[This review was collected as part of a promotion.] I have been using the Crest Whitening Emulsions Leave-on Teeth Whitening Kit for a while now and I have started to notice some differences in the shade of my teeth. I really like this product and how easy it is to use. I have always wanted to try out the LED lights for whitening teeth as I have not found a whitening gel that truly works. You don't need a lot of the whitening emulsions, just a little bit that you spread across your teeth with the little brush. Then you put the led light in your mouth for 2 minutes. Sometimes I do two rounds with the led light. My teeth are getting whiter with each use, but I have noticed that you have to be consistent or you won't see any progress.

[This review was collected as part of a promotion.] Very surprised and happy with the results this Crest - Crest WHT EMUL Light 18g/21mL 3ct delivered, and the best part is there are no sensitivity issues with my teeth. You will see results even from the very first time you apply the paste, and the LED light adds an extra boost to even whitened your teeth even more. Highly recommend. When it comes to value, you can spend hundreds in products that promise to deliver and they don't, on the other hand, this Crest - Crest WHT EMUL Light 18g/21mL 3ct is very affordable when compared to other products in the market and the best part is that it delivers and gives you the results you are looking for.

[This review was collected as part of a promotion.] I was so happy to receive this product.I have no health insurance that covers dental and this made my teeth feel so fresh when I opened it up yesterday to try it.My daughter even wanted to try it and she also stated she wanted to buy one.

[This review was collected as part of a promotion.] I received this product a while back from the Crest line and have started using this product routinely and I have noticed a big change in the tone of my teeth. I am a very heavy coffee drinker and that leaves nothing but stains on your teeth which can be stubborn to remove. I have also been on an aligners teeth system and as my teeth are shifting to the correct way I can see where darker shades from the overlap is. This changed the shade of my teeth after using it. It did not cause any sensitivity which is a plus!! I noticed that the bottle of product is on the smaller side but a little really goes a long way. Instructions are provided and very easy to follow. The LED light accelerator provides quick results!!! The emulsion product doesn't have a funny odor to it and it is very simple to apply with the brush applicator. I am very happy with my results so far and looking forward to what my next shade of teeth will look like!! I will continue to use this product.

[This review was collected as part of a promotion.] I've had the Crest White Emulsions Light kit for a couple weeks and have to honestly say I've been putting off trying it out due to my history of tooth sensitivity. In the past any type of whitening products, toothpaste or kits such as this, have increased my sensitivity and pain exponentially. This kit, on the other hand, specifically states it is safe for sensitive teeth. I finally tried it, leaving the gel in for 30 minutes and using the light for 3, as directed. The gel was easy to apply and dried quick. I don't have any extra sensitivity but am not sure how I feel about the whitening effect yet, after 1 use. The box states results after 1 application and I am not able to notice a difference yet. I will continue to use this kit, though, until gone to see if results improve since I didn't have any issue with my sensitivity. Will recommend at this time and update this review if my recommendation changes.

[This review was collected as part of a promotion.] I've tried using whitestrips before, and found the process uncomfortable and leaving my gums feeling sore. The Whitening Emulsions solves both of those issues -- I barely even notice the gel while it's on my teeth, and the LED light at the end feels futuristic and fun. The results are noticeable, although not dramatic

[This review was collected as part of a promotion.] This product is very is easy to use. Prefer to use this product over Whitening strips. Due to the sensitivity and pain in the past. I have used this product in the last several weeks, and have not experienced any sensitivity. I have seen a great improvement in the whiteness in my teeth and I’m very pleased with the results.
