[This review was collected as part of a promotion.] I was a little skeptical of this product before I got it. I have always been a huge skeptic when it comes to all of these different types of teeth whiteners. My oral hygiene is pretty great but after multiple decades of drinking way too much black coffee and red wine on a daily basis, they just don't glimmer like they used to. The applicator of this product is super easy to use, just squeeze a little bit and spread it across the teeth. The applicator is soft so you aren't clanging anything against your teeth. The formula is not very gewey or sticky so it is much better than those white strips. I genuinely feel like I noticed a difference after about 3 days of application. My teeth look brighter and I don't have to go through all of the hassle of UV light or the strips. It is perfect for when you just want some slight improvements to your smile and easy for every day maintenance.

[This review was collected as part of a promotion.] I love the Crest Whitening Emulsions! It works as well as the strips, but it's so much easier. I love the portability of the product (a little bigger than a lip gloss) because it fits into my purse. My favorite aspect, however, is that I can put it on my teeth and then forget about it: I don't have to time it or remove anything, so I can use it just about anywhere. I have used it up to 3x per day (directions say to use up to 4x daily), and I've had zero sensitivity. My first couple applications were a bit goopy until I figured out just how much product to apply. I will definitely get this again!

I started using these two weeks ago and for the first day it was fine. The problem is not that it doesn't do the job. I noticed my teeth were much whiter after the first day. Unfortunately, after the second day of using it, I started getting really painful headaches. I fell off my routine and picked it back up two weeks later and here my headaches here again. I know better than to keep using it at this point. The headaches can be really bad and literally keep me up all night.

The company tricks you and lets you think you are buying a product that will work. But it needs a light that they do not tell you about until you open the package and read the instructions.My box was semi- broken and 1 of the tubes spilled and was wasted.

I love white strips so I thought the emulsions would provide me with similar results. Unfortunately I did not see any results after about a month of following the instructions and using it properly. It's very hard to apply with the hard tip applicator / the paste doesn't get into every part of the tooth. Also, if your teeth are wet it just slides off…so you almost have to dry all your teeth with a cotton pad or towel first. But even after that…once you close your moth and your lips hit your teeth…everything just wipes off, and I just end up swallowing all of this stuff. I tried to love it but with all this work… and no results…I'm disappointed.

[This review was collected as part of a promotion.] I feel the product was like walking out of the dentist. It leaves a slight tingle to your mouth so you know it's there. I would have liked to see a slight window down the tube so you can see how much is in there. I am not sure how you will know how much is left. The tube is small enough to throw in your purse if you feel like taking it with you and easy for travel. I can't say I see a drastic difference in the color but I'm going to keep trying. It is somewhat messy to and hard to put on in that you will want to do it in front of a mirror to see where and how much you are putting on. Overall, it makes me feel like it's working. The tingle is not overwhelming and that only happens on the inside of your mouth where applied. There is no overwhelming taste.

[This review was collected as part of a promotion.] In my opinion, this product by Crest, is by far the best whitening option there is for at home use! It is super easy to use the applicator, just squeeze and brush on like a toothbrush and viola! It took about maybe 30 minutes for the product to dry completely and then I was on my way to go about my business. My teeth look fabulous and extra white, I had no sensitivity and seen major results after 4 days of use. I would definitely recommend

Feels like a lipgloss. Instructions are easy to understand. It doesn't dry at all and good results with repetitive use . Wouldn't repurchase though

This product is amazing! Been using it for three days and I can already see a big difference! Love it!!!

I've been using the wand application type on my upper teeth (upper only so I could compare) for 3 weeks now. No difference. Save your money.
