[This review was collected as part of a promotion.] I was a little skeptical of this product, especially since they said the gel dried and you didn't have to worry about it. But it's true - you just place the gel on, get it to dry, wait for 30 minutes and then use the LED light to finish. I noticed a difference in just 1 day of using it. I received this as a sample, so I know it's a bit pricey, but if you're looking for something effective, this is it.

[This review was collected as part of a promotion.] I have tried numerous teeth whitening products and had to stop using them due to my extreme sensitivity to my teeth and enamel. I had a friend try this product and suggest I give it a try. I'm so pleased I did! I experience almost zero sensitivity while I've used this product over the last month and my teeth look brand new again! Couldn't be happier all around with this product!!

[This review was collected as part of a promotion.] I'm so glad I got Crest Whitening Emulsions with LED Light Kit. It's really easy to use. It comes with the whitening gel, an applicator, storage pad, LED Light, and instructions. I found the kit to be effective in whitening my teeth over time and I'd recommend using it.

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 been using this for over a week and no sensitivity! Normally with strips or gel trays I get a lot of sensitivity. This gel is only applied to the teeth and doesn’t cause alot of gum burning like other products can. I don’t think it whitens quite as fast as some of the strips but the no sensitivity makes a huge difference. The gel and wand have a cute stand for your sink. The blue light has a built in 3 minute timer and turns off and beeps automatically. The light is comfortable to wear. The gel is amazing because once you put it on you’re done. Just wait 30 mins and then use the light for 3 minutes. No icky gel to spit out after treatment. You honestly forget it’s on!

[This review was collected as part of a promotion.] I have gotten whitening products from the dentist and I prefer those products since they make my teeth much whiter. I do like that this doesn't hurt my teeth at all and usually I am sensitive. There isn't a bad taste and it's really easy to use. As far as the whitening I would compare these to strips but just a step above. Slightly whiter in less time than strips but the real benefit is how easy it is to use, you can talk just fine with it on your teeth, and it doesn't feel weird. The light isn't used the entire time it is on your teeth, only at the very end which I also liked.

[This review was collected as part of a promotion.] Crest whitening kit comes with applicator, whitening cream and LED light. Its very easy to apply. Just squeez and apply on each tooth and use LED light for three minutes. I saw difference in my teeth at first use only. They were more whiter. Overall i liked the convenience and ease of use.

[This review was collected as part of a promotion.] I have only used the product once, so I haven’t seen results yet. However, I like the application and the light. It is easy to apply and I like that I don’t have to keep some sort of tray in my mouth the whole time. I’m curious to see if the light really speeds up the whitening process

[This review was collected as part of a promotion.] The crest whitening system is so easy to use it literally just takes seconds to apply and it has a nice minty taste to the whitening gel. You have to leave the gel on for 30 minutes which isn't really to bad. I actually did house work when I was waiting for the timer to end on my phone. When it did go off I then used the light for 3 minutes on my teeth and that's it you are done no having to rebrush or wipe anything off your teeth it dissolves on its own. Now it did cause a lot of saliva in my mouth and the gel felt funny on my teeth especially during the first application. But it did get to where I didn't even notice it after multiple uses. I love that I can boost my whitening experience and use it up to 4 times a day. I have been using it for only about 4-5 days now doing 2- 4 times each day and I have seen a significant difference in my teeth you can tell a difference in just that short amount of time. I have recently kicked the smoking habit and I have been trying everything to get rid of the nicotine stain on my teeth and this is the only thing I've found so far that is actually making a difference in the appearance of my teeth. I am absolutely thrilled to have found this and will continue using it to see just how white my teeth will and can get with it.
