3D Whitestrips, 1 Week Smile Transformation, Whitestrips 3D White, Teeth Whitening Strip Kit, 14 Treatments (Each with 1 Upper/1 Lower), 28 Strips

Works exactly as they should. I recommend drying your teeth with a tissue before applying

We are BIG into natural living, so I was NOT one who wanted to whiten our teeth using unsafe ingredients. The ingredients in these are overall pretty decent, EXCEPT the SACCHARIN. That said, we had a dentist recommend we whiten one of our teen's teeth BEFORE braces because they said if we whiten AFTER braces, they would have to REMOVE & REPLACE any fillings in the teen's teeth because the fillings would be the color of her teeth that were stained from silent reflux due to hiatal hernia issues caused by a tongue tie, as well as her lips & buccals were also tied, causing the dental issues. We did NOT want to have to have her fillings redone for several reasons, so we decided to try the home whitening. I was NOT happy that there is saccharin in them as it is TOXIC, but I felt I had to compromise because I felt 14 days of saccharin on her teeth for 30 minutes, would be less harmful than having to replace the fillings that would be in her mouth for several years, not to mention that every time a filling is redone, part of the natural tooth structure is removed even further, & we felt that was the greater risk long term. After reading countless reviews on several listings for the Crest strips, I decided upon these ones. I saw "professional" ones that were pricier & I was going to buy them, UNTIL I saw the reviews that said the strips were dried out, the boxes came empty, etc. I also considered the ones for SENSITIVE teeth, but was concerned they would not whiten quickly enough, as some reviewers had stated. These ones said "professional effect" so I decided I would go for it after reading the reviews. We are SO happy with them! Our teen used these for 14 days, 30 minutes each time, daily. She brushed her teeth before (she did not see the note on the box that says to avoid brushing right before) & rinsed with a Waterpik after to get the stuff off her teeth thoroughly. We were THRILLED that when she went for a filling on day 14 to repair some damage due to the ties & using straight charcoal powder on her teeth (UNBEKNOWNST to me!), her teeth were as white as they could be (B2) without heavy duty professional whitening. The DENTIST was VERY happy with the results as well. We are VERY pleased & did not realize how much the silent reflux (which we did not know was happening) had impacted the color of her teeth. Her teeth are SO white now & ABSOLUTELY BEAUTIFUL! We are now going to buy strips for our other teens & tween to use, because they also had silent reflux until they had their unknown tongue, lip, & buccal ties released recently. Their teeth are nowhere near as stained & our one teen's were, so I am not sure if their teeth will be as white as our one daughter's are after using these strips, but I want to let them try. Our teen is SO much more CONFIDENT now & smiles SO much. She was NEVER bothered by her teeth before, but I think that now seeing them look so absolutely BEAUTIFUL, has helped her teeth to look as great as she now feels after having her ties released, & her airway expansion in progress. Had I known her teeth were so stained, I would have used these sooner. After I get my kids' teeth done with these strips, I may splurge on some for me too. I WOULD purchase these again & have purchased them for my other kids now.

I'm a fairly lazy girl, and I don't use these often. But when I do, they showed results after the 2nd try for me. I already have somewhat white teeth so it doesn't max out and show how white it can whiten my teeth. My niece who has purchased before had really yellow tints in her teeth for ages. This product was able to get rid of it and now her teeth is noticeably much brighter. I'm also a girl who has fairly sensitive teeth. I can't bite down on ice cream, it just feels like a cold shattering sensation going through my teeth and I hate it. I'm also a girl who is not good with keeping time and direction so i did leave this on 10-15minutes extra of what the package recommends. The first experience was tricky, I didn't know how to apply it and the strips are a little shorter than what I hopped it would reach. These strips will only cover 5-6 teeth on top and 6-7 teeth on the bottom. It won't rich to your molars, just the front and most visible part of your teeth. Don't know how i feel about that, because I would have liked it if it reached a little farther down, but that's my opinion. Going back on topic, after taking it off, there isn't any pain or toothy aches right away, it happens after a couple of hours. I usually do these at night and then wake up having this aching sensation on my teeth. It was uncomfortable at first...and honestly will be for awhile now, but for the results I'm up to sacrifice the pain for a brighter smile. Overall I give this product 5 stars, because this product does work & the trade-off ache is worth it for me because it's only temporary. I recommend waiting for this to go on sale with their usual $5 off. I know this can be pricey and I debated getting this for a year! (Yeah, I held my wallet close) but save as much as you can even with that $5 because that could be used for food...& coffee.

Works very well BUT in my experience it is far more difficult to keep strip for bottom teeth in place. No problems getting top strip to remain. Maybe there is more moisture in bottom part of my mouth ? Anyway, a challenge to keep bottom strip on my teeth. Had to ‘give up’ a few times and just use top row strip.

EDIT: Just turned 73. I use Colgate Optic White Advanced and even being a coffee drinker, it keeps my teeth pretty white. I hadn't used Crest Strips for probably about seven years or more. BUT there was a NICE coupon offer and my total was less than 30 bucks so.... In the past, I hadn't gotten the Express White strips included, so that was a nice bonus. I have been using about four days and even though my teeth already looked pretty good, see a big difference. TIP: FYI, I have a small space between my teeth, so I CUT the strips in half so they cover more of my teeth. I also notice it's not my front teeth that start to get a little yellower, but the back ones. I also have a slight chip on a front tooth and didn't want to use on that one (my top front teeth are already pretty white), so I cut the strips to fit where I wanted them to. BOTTOMLINE: WELL worth the money_________ AND TIP! IF your teeth/gums a little sensitive, just use for less time. Even though doesn't bother me much, I just wear 20 mins at a time instead of 30. I only need a slight whitening and sometimes I only use a half box and save the other for when I notice I need a bit of a touch up, or white up! ______________________________________________________________________________ UNLESS your teeth ARE REALLY REALLY STAINED and you need a professional whitening, if you just want to amp up your smile...I would say go with these.. THE GLAMOROUS versions are MY FAVORITE of ALL the whitening strips I have tried and I have used many over the years. I started using the original (and only one out) about fifteen years ago, that was pretty good. I saw results. I have gotten the PROFESSIONAL Crest product which was WAY MORE money. I was not impressed. My teeth are really fairly white, I just wanted to make them a bit brighter and get rid of just a little yellow starting at the base of some teeth. So about a year after using the Professional Crest product, I went with this one. It was less money and unless you really need to get rid of over a decade of yellowing, lots of coffee stains, I say this one works JUST GREAT! It is brightening my teeth and for less money. THIS is the one I will get again in about six months or a year when I want to just noticeably BRIGHTEN my smile!

I love amazon for selling these at the price they do! I've probably used about 5 or 6 boxes of these and my smile has never been so white. I get tons of compliments and people always assume that I get them professionally whitened. Looking back at old photos, I don't know how I survived! Despite brushing with the most whitening toothpaste I could find, my teeth would absorb every stain and looked downright awful from all the stains I had from drinking iced coffee all the time. I didn't have enough money to get my teeth professionally whitened, and the only white strips available were crest white strips classic which were annoying to use. When Crest White Strips Advanced Seal came out, I had to give them a try. Luckily for me, the changes were drastic. They improved my self confidence, which led to other changes for the better. If you've tried other white strips before and were annoyed with how they slide around and make your mouth full of saliva, this is your product. The advanced seal holds them in place tight and it's true that you can drink water while keeping these on your teeth. If you have really sensitive teeth, this might cause you some issues. I've left them on for longer than the recommended 30 minutes before and it made my teeth ache. One time I fell asleep with them on by accident... big mistake! My teeth were in pain for about 2 or 3 days. I have also experienced intense, but very short spikes of pain on one tooth when using this product, especially if I leave them on for too long. However, after using them every day I developed a tolerance to the sensitivity and pain, and I can now use these 7 days a week without issues. The results are totally worth the effort, especially at this cost! I transformed my smile from yellowish coffee grunge to fabulous illuminating white after about 3 straight months of using crest white strips with advanced seal. Now, 6 months later I have been able to maintain my bright smile by using a strip once a week and brushing with a whitening toothpaste twice a day, in addition to flossing once a day. I'll try to include a before & after picture (jeez, I'm so embarrassed to show my before picture!!) so look in the product images for that. Bottom line, can't go wrong with crest white strips that have advanced seal! They are powerful and give professional results.

Easy to use, no slimy gel. Pretty dry. Minimal difference. No better than generic lesser expensive strips. Plan on trimming down to use. Wouldn't buy again.

It's Crest - so still the best of the whitestrips. Work fast and easy. A regular fan of the product.

Excelente producto, blanquea súper bien los dientes. Importante seguir las instrucciones de uso, y no dejar más tiempo del indicado, ya que podría causar sensibilidad. Es la 2a vez que lo compro.

ممتاز بس امشو على التعليمات بالضبط

Excelente producto

Blanquean muy bien, sí quedan sensibles los dientes pero solo al día siguiente y después la sensación desaparece, sin embargo lo vale por los resultados, solo me gustaría que fueran más largas, sobretodo la de los dientes de abajo es muy corta y no abarca muchos dientes.

Me dejo un poco sensible los dientes y no te los deja súper blancos. Si sirve
