Don't waste your money! It doesn't work!
This product is just a marketing gimmick that promises whiter teeth but fails miserably. I've been using this product twice a day for over a month and don't see any improvement. Unlike other brands that highlight the high percentage of hydrogen peroxide in their whitening products, Crest doesn't disclose that info on their packaging or in online ads which. leads me to believe they have something to hide. The over-the-counter whiteners simply don't contain the same high hydrogen peroxide content that will give you the light & bright smile you can only get in your dentist's office.

Not for sensitive people
Not for sensitive teeth/skin. Applied this as directed and my whole mouth started burning Basically immediately. Corners of my lips got really irritated. Back to strips for me

The well-being and comfort of our consumers are some of our top priorities, and we are disheartened to hear that you have had some oral irritation with your recent use of our Crest Whitening Serum. All of our products go through extensive testing to ensure their performance and safety, and this is not at all the experience that we would like you to have. As with any oral care product, some consumers may be more sensitive to certain ingredients than others, but since there was some irritation immediately after the first application, we would recommend discontinuing the use of the product. We would love a chance to learn more about your recent experience, so we are better able to assist you as well as gather some information for our Quality and Safety Teams, and encourage you to give us a call at (800) 395-8423.

Terrible Reaction
I couldn't finish the 14 day treatment. I used this pen for only 5 days. This product gave me terrible headaches. I was miserable. Unfortunately, I didn't see a difference within the 5 day timeframe of me using this product. I hate that I wasn't a good candidate for this product.

We appreciate you taking the time to share your experience with our Crest Whitening Serum. We’re sorry to hear that you didn’t experience the desired whitening effect and that the product caused headaches. We inspect our whitening products for quality and thoroughly evaluate them to ensure they are safe when used as directed and that they deliver the best results. The average user will notice whitening after 14 treatments, provided the serum is applied correctly. Typically, applying the serum to dry teeth in a downward motion and refraining from eating or drinking for 30 minutes helps achieve that bright smile. However, we understand that some people may be intolerant to a particular formulation of specific oral care products. We take the health and safety of our consumers very seriously, and we are glad to hear that you are no longer using the product. We always recommend discontinuing use if it is causing significant pain or discomfort. We’ll share your message with our Quality and Health & Safety Teams. We want to learn more, so we provide you with the best assistance. Please call us at (800) 492-7378.

Not a fan of the applicator
Not a fan of the applicator wand. It doesn't transfer the serum easily on my teeth and a lot of product stays on the applicator. I wish it was a pen.

We're sorry to hear you're unhappy with the application of our Daily Whitening Serum, and would like to help. We recommend you dry your teeth with a tissue or paper towel before applying. Paint the Serums in a downward motion onto your smile teeth, being sure to cover them completely. So we can help you further, please give us a call at (800) 395-8423.

Serum vs strips
I usually use the Crest 3D Whitening Strips so I am comparing Apply & Go Daily Serum to that. It is convenient to apply the serum and then be able to go about your day rather than with the strips you put them on and then have to wait 30 minutes before you can remove them. So that is nice. However, the directions say to apply this serum 4 times a day for the best results and that’s a lot. As far as seeing results…I notice a big difference immediately when I use the strips but the serum I do not notice much of a change. Even after using the serum once a day, for over two weeks. My teeth just aren’t that much whiter. After two weeks of the strips, my teeth are extremely white and I don’t even need to use the strips every day for those results. Also, the serum lasts about a month when using once per day. So if you’re using it more often it probably wont last that long. Just adding that in here in case it’s relevant. With the strips you can choose a month supply or 14 day etc. So I prefer the strips over this serum 1000%. I won’t be purchasing this again.

Many thanks for leaving this detailed review, Hhartland4321! Crest Whitening Serums and Whitestrips are both highly effective and will get your teeth as white as you want them to be. Both products depend on application frequency to determine efficacy and will get your teeth as white, or whiter, depending on how often you apply. However, if you don't think the serum was as effective as you hoped, please call us so we can gather some information on your product to share with our Quality Team and be able to help you. Our number is (800) 395-8423.

My go-to
My favorite whitening product! Whitening strips really hurt my teeth, but this is gentle yet effective. I’m not sure it’s the healthiest way to do it, but I like to put this on and then pop in my invisalign retainer before bed. I don’t use it all the time, but if I have an event or need a quick touch up this is my go to!

Used daily with zero effects
I have painted this on my teeth before bed every night for the last month and a half. I wear my retainer on top of it so it stays in place, and it stays on for 7-8 hours. I literally cannot see one ounce of a difference on my teeth. I guess if you're going to use it you have to put it on 4x a day.

We're disappointed to hear you aren't seeing the great whitening results as expected, Mark. In some cases teeth stains can be stubborn, and may need additional whitening treatment. We don't recommend applying this serum to your teeth and wearing a retainer of this serum, as it hasn't been tested for this. If you ever have questions or would like to learn more about our Crest Whitening Money Back Guarantee, we invite you to give us a call at (800) 492-7378.

Horrendous, waste of money. Do not buy!
Bought this 2 weeks ago, terribly underwhelming. Application is horrendous. Never sticks to teeth and the wand provided is useless. Saliva just washes everything off of teeth within seconds. Just stick to white strips as this may as well be lighting money on fire.

We're sorry to hear this, Cole. We always want our products to give your smile a great whitening experience, which we stand behind with our Crest Money Back Guarantee. After thorough quality testing, this surely isn't the result we expect. So we can learn more and share some information with your about that guarantee, we ask that you give us a call at (800) 492-7378.

Do. Not buy.
I have tried to use this product but it sucks. The paste always gets stuck on the applicator and ends up on my lips and gums. It is. NOT easy to apply and I have to keep my mouth open for 30 minutes. Drying your teeth does not do anything. There is always saliva building up and literally takes the paste right off my teeth. Waste of time and money. Stick to the strips.

We're sorry to hear our Whitening Emulsions didn't stick and was messy to apply, and would like to help. Please know, there are many quality checks in place to help ensure only the best products reach you. We recommend you dry your teeth with a tissue or paper towel before applying. Paint the Emulsions in a downward motion onto your smile teeth, being sure to cover them completely, and then avoid eating, drinking, smoking, or chewing gum for 30 minutes. Avoid “brushing” in a circular motion while applying, and avoid reaching too far back into your mouth where the product will tend to mix more with your saliva. So that we can help you further, please give us a call at (800) 395-8423.

Not great
Causes teeth sensitivity and I don’t think it works all that great. It doesn’t stay on very well. Teeth have to be super dry.
1 reply from Crest team - 2 years ago
We’re very sorry to hear you're disappointed with the Crest 3D White Daily Whitening Serum. Our whitening products go through extensive safety tests to ensure they are safe to use as directed. We genuinely hope your teeth are feeling better, and we will be sharing your experience with our Safety team. With any products containing the enamel-safe whitening ingredient, hydrogen peroxide, temporary sensitivity may occur for some users. This sensitivity should subside with time, and if not, discontinued use is encouraged. For best results with this applicator, pat the teeth dry before application, and avoid eating or drinking for 30 minutes. We'd like to learn more from you, so please hold onto the product for at least 2 weeks, and give us a call at 1(800) 395-8423.

Easy to Use - and It Works!
I love this stuff! Super quick and easy to apply, I very much prefer it to messing with the strips. I put it on after I brush my teeth and then don't have to think about it again. I started seeing results after 2 or 3 applications. The results aren't drastic, but they are noticable. I have super sensitive teeth and I do feel a smidge of sensititivty with this treatment, but less than with any other whitening product I've tried. I have a crooked tooth in front and I have had a little trouble fully covering this tooth with the applicator - if several of your teeth aren't very straight, you might have better luck with strips. But for me, that little downside is more than made up for by the convenience of this product.

I love how easy this is to use and it works so well! I have professionally molded whitening trays from the dentist and I find myself using this product more often because it’s so quick and easy.

Whitens
[This review was collected as part of a promotion.] This crest whitening emulsion with the built in applicator really does work. I'm a smoker and my teeth aren't the prettiest, after just a few uses it brightened them up. I am more happy with my smile now. Thank you crest

Great
[This review was collected as part of a promotion.] This product works very well. First off, the instructions are fairly simple and easy to follow. After washing my teeth, I apply the whitening emulsion and leave it on. I enjoy how it has a minty taste and not a chemical one. As for whitening results, I can definitely say that it works. I am a regular coffee drinker and my teeth are a bit yellow sometimes. After using this for a few weeks, my staining definitely decreased and my teeth looked a few shades whiter. I definitely recommend this, as it is cost efficient since you can use it for long periods of time.

Easy, Convenient Whitening
[This review was collected as part of a promotion.] I have been a long time Crest 3D White product user so I was excited to try this whitening product. I have to say, I love how convenient this product is to use. Sometimes I just do not have time to put the whitening strips on for 10-15 minutes, remove, and brush. This makes whitening convenient without an excuse for not using the product. I have noticed an improvement in the brightness of my smile. Instructions are simple to follow.
