[This review was collected as part of a promotion.] Easy enough to use, and a noticeable difference in color when you compare before and after pics, but I didn't notice as much without the pics. Definitely take before and after pics, otherwise the changes may be too subtle to notice. Would use it again.

[This review was collected as part of a promotion.] Okay this Crest Whitening Emulsions is going to be a hit. I've only been using it for a few days as it arrived a few days ago. I love that it is small enough you can carry it with you and use up to four times a day (for best results). The small applicator is perfect for a thorough coverage of each tooth. I know this whitener is working because of the already difference in the teeth next to my trauma tooth (it will never change color). Until I have that tooth actually replaced, it has been a good guide as to my cleanings. I can't wait to see the final results at the end of the tube. I will he looking for this item when Crest have their sales.

[This review was collected as part of a promotion.] I have long struggled with trying to whiten my teeth due to extreme sensitivity. I've tried so many over the counter products as well as professional teeth bleaching at the dentist office, all resulting in painful sensitivity that prevented me from continuing the process. Then I tried this. My teeth are finally white and with zero pain or sensitivity! I am beyond happy with this. It's super easy to use. Just paint it on and go. I like that it can be used several times a day and the best part is that I started noticing the change in my teeth in just a couple of days. i use it in the morning, after lunch and before bedtime. I've gotten many compliments on my smile looking brighter so i know this is working. Thank you for making a product that actually works and is safe for sensitive teeth!

[This review was collected as part of a promotion.] I have been using this for 4 days and I can see a big difference in the lighting of my teeth. It is easy to apply and the taste is not bad , works better than most other whitening products I have used . Does not leave a weird residue on teeth

[This review was collected as part of a promotion.] This is great for use when your busy and on the go. Small compact size fits in any purse or small bag. Easy to use and works great! Quickly able to apply and go on with my day. Definitely will be recommending to others.

[This review was collected as part of a promotion.] I really like this Crest Whitening Emulsions Treatment. I like that it is easy to use and it is very convenient because you just apply and go! You have more control with this because you choose what teeth you want whitened. It says you can use up to four times per day, but I only used it once per day and I noticed that my teeth were whiter!

[This review was collected as part of a promotion.] I have been using crest 3-D whitening strips for a long time and used to get great results with them but as expected they take quite a while so I would have to use them for at least two weeks before I noticed noticeable differences. They're also a little bit harder to keep on your teeth sometimes it would slide off or they wouldn't be on really well. Compared to the 3-D whitening strips the emulsion whitening is so much easier to apply. I started seeing noticeable results within four days. It could vary depending on how much and whitening is required though. No intense cleanup is required and I am able to do my normal day-to-day activities while I have this on.

[This review was collected as part of a promotion.] I have used the 1 hour express for my top teeth only and it works amazing after completing the 7 days of strips. Well worth the $. I saved the strip that is supposed to be used on the bottom teeth and used them for another 7 days on my top teeth and saw an even better level of bright white.

[This review was collected as part of a promotion.] I love that I can whiten my teeth while driving. This is perfect for my ever so busy schedule. The taste isn't awful and it's still too early to tell how well this item works. But anything is better then nothing.

[This review was collected as part of a promotion.] Crest Whitening Emulsions on the go is so very simple to use. I love it. Just squeeze and apply. Can be used anywhere. Most whitening products are very sensitive on my teeth, this is not! No sensitivity at all. It actually works the first time. I noticed it immediately. Great product.
