Works great! I would recommend this product.
Flavor Name: Unflavored Size: 1 Count (Pack of 28)
I tried these strips as I was invited to a wedding. The first thing I thought of was smiling and noticed my teeth had staining! After 1 week of use my teeth have become a lot lighter. The stains on my bottom row are not visible anymore! There was a lot of sensitivity on the bottom row the first day but it decreased after each use. I am going to use the remaining 7 packets closer to the wedding to have a lighter smile. I love that they don't get you that white veneer smile that looks out of place. Note that you have to leave the strips on for an hour and I recommend to stop drinking coffee or anything that stains during your treatments. I would recommend this product if you want lighter teeth for extra confidence at special events in a week! ... show more

Must have product
Flavor Name: Unflavored Size: 1 Count (Pack of 28)
These are my favorite and go-to whitening strips. I have not found any other teeth whitening products that are as effective while being comfortable. I drink black tea daily and these strips help me maintain a nice, bright smile. This is a must have and repeat purchase for me.

Sensitive & Pleased
Flavor Name: Unflavored Size: 1 Count (Pack of 28)
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. ... show more

4 stars and worth the $

Review Image by Alex silverstein
so I never had whitened my teeth before (other that the 4 times I used a charcoal activating toothpaste) and I thought this would be a scam, but my brother had some yellow teeth and then he surprised me one day with a white smile. For him, this would be worth the 5 stars! I was blown away but I still didn't try it. I kept putting it off but I wish I had done it sooner. My teeth were off white. I don't smoke, but I think drinking coffee and skipping out on flossing caught up with me that there was a slight yellowish tint in some lighting but it was only noticeable to me. I have small teeth and big cheeks so usually when I smile and talk you only see my top teeth, which is good because I have a chipped tooth at the bottom. Anyway, I am graduating college soon and had to take some pictures so I finally remembered that I wanted to give this a try. I feel more confident when I smile now but here's the issue. The bottom strip is not the same size as the top strip so the bottom strip did not give as great of coverage as the top strip. It also slipped off; whereas, the top strip was perfect at sticking on to your teeth. Crest should consider just giving 2 top strips and I'm surprised they have not done so seeing how people have been making this complaint for over a decade. The change on my teeth were not as dramatic a change as my brother's. I was hoping it would be lifted 2 more shades but still I am very impressed with my top teeth. My bottom teeth kinda look the same from day 1. It is still well worth the $ to feel confident when you smile. I plan on buying them again in a few months. Also most days I did not get a zing sensation (you get it from having sensitive teeth) but the days that I left the strips on for too long I did feel it. If I felt a zing, I'd wait a few days before putting in the next strip. I took some pictures of my teeth to show the transformation. I think the teeth look really good in sunlight but under certain lighting like white lights- not as great. if you are debating this, don't overthink it. Give it a try! :D ... show more

No more pearly yellows!
Flavor Name: Unflavored Size: 1 Count (Pack of 28)
YOU SHOULD TOTALLY BUY THESE WHITESTRIPS IF YOU REALLY WANT WHITER TEETH. Don't whine about sensitivity, it says right on the box that it can happen. I had no issue with the "goo" on these bleaching my clothes or fingers. They only became gooey when I removed them from my teeth. I had been thinking about whitening my teeth for awhile -- I had the Rembrandt 2-Hour Whitening kit, but that thing TORE MY GUMS UP. It did whiten my teeth slightly though, but not worth the $50 and the pain. I asked my dentist about getting professional whitening, but he said it's basically the same thing as everything out on the market that has a tray (like the rembrandt kit), just wildly more expensive (I love his honesty). I had the old whitestrips from about 3 years ago -- they didn't do too much for me. I got this new set of Crest Whitestrips in a fit of optimism. The shipping took a little longer than most stuff I get from Amazon, but nothing outrageous. The packaging was nothing to hoot at (mine came wrapped in the Classifieds section in a manila envelope, the box was a little crushed, but the innards were fine). I read the instructions, and DID NOT brush my teeth beforehand, and slapped those suckers onto my lower and upper teeth. I like these better than the old whitestrips, they aren't gooey and slippery like the old ones. They're more a tacky feel, like they get sticky only when they get wet, so you can readjust them without them sliding all over your mouth. I do have a fairly wide smile, and the upper strips cover just about all of it, and the lower ones cover about 6 of my teeth. These don't taste as bleachy as the old ones, and they didn't irritate my gums AT ALL either. I've been using them every other day to cut back on the risk of sensitivity (but I fell asleep with them on one day, which you're NOT supposed to do - so i ended up leaving em on for like 2 hours instead of just 30 minutes, so I had some sensitivity after that session that faded eventually). I noticed a visible difference in the shade of my teeth within 3-4 treatments and I think i still have about 5 packets left. My teeth are pretty white now, but not unnaturally white (by unnatural, i mean like Ross in that episode of Friends where he dates the girl with the blacklight). My teeth aren't paper-white, but let's be honest -- that would be creepy. The walls at my job are a pale cream color, and my teeth are now whiter than the walls. The only thing that could make these better is if they paid my bills and told me they loved me once in awhile. Oh, and maybe included a whitening scale, so that you could compare your teeth when you start to when you finish. ... show more

WOWZA!!!!!!!!!!
Flavor Name: Unflavored Size: 1 Count (Pack of 28)
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. ... show more

I love using these! Okay, so lots of people have commented on how these can increase your sense of sensitivity and it has a nasty taste in your mouth--I'm going to be honest: I don't really taste anything. It says not to swallow anything so maybe someone accidentally swallowed some and it was gross? Idk. And as far as sensitivity goes, I have sensitive teeth anyways so I was SUPER nervous about using these but I took a risk, and I've continued using my normal toothpaste: Crest's Whitening Therapy toothpaste that also helps majorly with sensitivity. I don't know if it is the toothpaste that helps but I haven't felt an increase in sensitivity. :) If you have problems with sensitivity but want to whiten your smile, my Dentist told me (I had previously asked for advice on using these strips) to decrease how often you leave them on and for how long. If you feel any weird tingling or pain while the strips are on after a bit, take them off and try again the next day or the next. Totally up to you how long you use it. JUST DON'T FALL ASLEEP WITH IT IN!! I don't know what happens but it's all over the instructions as a warning. haha Also another thing, in the instructions (You can tell I was worried about using these haha) it mentioned to avoid brushing your teeth right before you use the strips. It didn't explain why so I either just do it at the end of the day or wait a while after brushing my teeth, like 30 minutes to an hour if you can. And I always brush my teeth after-cuz the whitening gel is all over your teeth and it feels gross and weird so I rinse first and then brush my teeth after a few minutes--I don't want to immediately brush off what I want to whiten my teeth! And I know everyone's been putting up BEFORE and AFTER photos of their teeth. Well I totally blew it I didn't take a before picture... But I'm getting married in June so the real test is if my smile will match my dress!! *Fingers crossed!!* Good luck on your adventures! OH I ALMOST FORGOT! So children: It disclaims in the package instructions that white spots could appear or stains on your teeth could brighten temporarily. Let me emphasis the word: TEMPORARILY. TEMPORARILY. I have small lines on my teeth from braces (I wasn't a diligent brusher at 12 years old) and they brightened for like a day. I used it again (I do every other day) and they weren't as bright. So DO NOT WORRY if you experience similar results. Keep calm and keep on whitening. :) ... show more
