We're sorry to learn our Daily Whitening Serum isn't as easy to use as you expected, Mikey. To make it easier to apply, we suggest you "air dry" your teeth by inhaling air with your mouth open. You can also dry your teeth with a paper towel before application. So we can help further, please call us at (800) 395-8423.

Love it
The wand applicator makes it convenient for on-the-go whitening, and the formula is easy to apply without a strip. I love the texture of the whitener it give the pack great value

Very Happy with this purchase
As someone who whitens their teeth often with crest white strips. I am very pleasantly surprised with this product. I go through ALOT of strips! I have recently gotten a bonding on my front tooth and was searching for an alternative to the strips, super happy with how easy this is. I have also found that it causes considerably less sentitivity. Although i still love the stips, I am really happy to also have this alternative for a gentler whiten. This may be my new preferance. Looking forward ot cotinuing to use it. Makes my teeth nice and white, little to no sensitivity at all, stays on teeth and has a pleasant taste to it. If your addicted to white teeth like I am, I would add this to your arsenal!

Beautiful Pearly Whites Achieved!
My mom tried this and has advised the product is great! It’s priced fairly. The packing is simple, doesn’t have a bad odour and it whitened her teeth immensely!

Only use the light twice and the battery's already dead.

We are always excited to help our consumers get their whitest smiles, and we can understand the frustration with the light not working after two uses, Delores. All of our products go through extensive testing to ensure that they reach you in perfect condition, so this is not something we would expect, and we will make sure this information reaches our Quality Team. There could be a few factors that may be affecting the lights' ability to work. We would suggest checking to make sure that the kit is not past its shelf life, as well as allowing a rest period of 8 hours in between uses to allow the battery to recharge itself. We would love a chance to learn more about your experience and encourage you to give our team a call at (800) 395-8423.

Whitening must have !
Crest Whitening Emulsions works great for brightening teeth without sensitivity. It’s easy to apply, mess-free, and doesn’t require rinsing. The results are noticeable with consistent use, making it a convenient option for on-the-go whitening! No weird smell or ingredients. Definitely worth the money

Doesn't stay on teeth
The product is slimy, slides right off of your teeth after application. Such a waste of money.

Game changer for those with a strong gag reflex
I have a strong gag reflex and have never tolerated whitening trays made by the dentist. I don’t even tolerate the white strips. This emulsion doesn’t trigger me to gag, is pleasant to keep on my teeth, and I love that the accelerator light is included. I am seeing results, but I anticipate having to use it regularly because I am a coffee drinker. Worth it though. I always hated smiling in pictures with friends and family who have sparkling white teeth.

Easy to use
So easy to use. Just swipe it on after you brush your teeth and you’re good to go. I don’t like the strips because they are so uncomfortable in your mouth- this is “slightly” uncomfortable but honestly the best whitener I’ve tried.

Add to cart now! LOVE IT
I’ve been using this for 5 days and I’m confident this will make great stocking stuffers for the family! I’m a fan of progression shots and over just a few days I have a noticeably whiter smile. Like: works really good. Doesn’t have a poor or sour taste. Easy to apply. Noticeably whiter after a single use. No sensitivity issues. Comes with a convenient holder. Dislikes: directions are pretty vague, I was afraid to close my mouth after applying. 30min seems like an eternity to me personally. The LED light doesn’t have a holder, kinda unsanitary. The substance must be put on DRY teeth and I found this to be complicated. Pricey, but worth it!!!

Amazing product!
After using it only twice, I had someone ask me what I had done to my teeth, which is crazy. I just used it for the third time and I can totally see the difference. I wish I had known about this sooner! Also, I love that the strips are sticky and stay in place which is a huge improvement from the strips I’ve used in the past.

The LED light wouldnt turn in
The LED light didn’t work! What is the point of this if half the product was a bust? Disappointed!

It works!!!
I love this product! I saw a difference after the first use. My teeth didn’t whiten but they started to shine. After an about a week, I saw a huge difference. My teeth were whiter and looked clean. It even kept my breath fresh through the day. I did use the product 3-4 times a day the first week and a half. After that, I used it once a day.

Apply and go
As someone who's always looking for ways to brighten my smile, I was eager to try this product, and it did not disappoint. First and foremost, the convenience of this whitening gel is unmatched. Unlike traditional whitening strips or trays, the leave-on formula means I can easily incorporate it into my daily routine without any hassle. I simply apply the gel directly to my teeth, and I'm good to go – no rinsing or brushing required. The LED accelerator light adds an extra boost to the whitening process, helping to accelerate results and enhance the effectiveness of the gel. I love how compact and portable the light is, making it easy to use anywhere, whether I'm at home or on the go. What sets this kit apart is its gentle yet effective formula. I have sensitive teeth, so I was pleased to find that the Crest Whitening Emulsions didn't cause any discomfort or sensitivity. Instead, they gradually and safely whiten my teeth, leaving them looking noticeably brighter and more radiant. I also appreciate the sleek and stylish design of the packaging. The small size makes it perfect for travel, and the easy-to-use applicator ensures precise application every time. Overall, I highly recommend the Crest Whitening Emulsions Leave-on Teeth Whitening Gel Kit with LED Accelerator Light to anyone looking for a convenient, effective, and gentle way to whiten their smile. It's become an essential part of my oral care routine, and I couldn't be happier with the results. Five stars all the way!

[This review was collected as part of a promotion.] I got this Crest WHT EMUL Light 18g/21mL 3ct to brighten my teeth - the product seemed to work ok - I have tried a couple different kind of whiteners and this seems to be working for me right now. Easy to use and does a good job.

Not for me
Definitely did not see a difference after one day or even a week as this product claims. Main issue was how to use the product and the amount of time you need to dedicate each day (~ 65 mins). After you squeeze the product on the wand you’re supposed to wait 30 minutes before you apply the LED light, but I noticed by the time I was supposed to use the LED light most of the product on my teeth was gone. And you had to do this twice a day so not as convenient as say the whitening strips.

We're so sorry to hear you weren't a fan of our Whitening Emulsions, and that much of the product came off before you were able to use the LED light. Please know, there are many quality checks in place to ensure only the best products reach you. Our Emulsions are designed to keep working long after you apply, wo even if it appears most of the product has come off of your teeth, you're still getting whitening benefits while using the LED light. So that we can learn more about your experience and help further, please give us a call at (800) 395-8423.

Poor
I am very upset with this purchase. The light is NOT rechargeable and I will have to purchase another one. If I knew this I would have got the cord one you put into your phone! I also have not seen progress in my teeth.

Destiny, we’re sorry to learn that you haven’t seen the whitening results you were hoping for, and that you’re unhappy with the Accelerator Light. The light is designed to last for the duration of the kit. Whitening results depend on several factors, such as application frequency, your age, and how yellow your teeth are. Most consumers will see whitening results after just a few uses. So that we can help you further, please give us a call at (800) 395-8423.

Bad quality
I bought this kit and it has not made my teeth white. I also was frustrated because the light is not rechargeable and I don’t expect myself to pay everytime for a new mouth piece. I really wish I could get my money back but I had already opened it!

Not worth it
this product did give me tooth sensitivity, it has to be done twice a day, and must make sure mouth stays open during waiting period. I would have rather gotten the whitening strips if I would have known this was going to give me tooth sensitivity.
