I would recommend this product. - 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! Review: Sensitive & Pleased - 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. ## Features - Plastic - Made in USA or Imported - 8 Levels Whiter in 1 Week - Accepted by the American Dental Association - Uses the same whitening ingredient as dentists - Enamel Safe & Effective - Features our Advanced Seal Technology no-slip grip so strips stay put during full application time - Includes two 1-Week Smile Transformations of 7 treatments each ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001OOLLVS | | Active Ingredients | Hydrogen Peroxide | | Age Range Description | Adult | | Best Sellers Rank | #11,717 in Health & Household ( See Top 100 in Health & Household ) #13 in Teeth Whitening Strips | | Brand | Crest | | Brand Name | Crest | | Customer Reviews | 4.5 out of 5 stars 15,707 Reviews | | Flavor | Unflavored | | Global Trade Identification Number | 00889714000052 | | Included Components | Applicator | | Item Dimensions | 1.64 x 5.5 x 5.65 inches | | Item Form | Strip | | Item Weight | 1.6 ounces | | Manufacturer | Procter & Gamble | | Manufacturer Part Number | 3700020179 | | Model Number | 3700020179 | | Number of Items | 28 | | Package Size Name | 28 Strips | | Product Benefits | Whitening | | Set Name | Glamorous White 28 Strips | | UPC | 889714000052 | | Unit Count | 28 Count | ## Product Details - **Active Ingredients:** Hydrogen Peroxide - **Brand:** Crest - **Item Form:** Strip - **Number of Items:** 28 - **Product Benefits:** Whitening ## Images ![3DWhitestrips 1 Week Smile Transformation At-Home Teeth Whitening Kit, 14 Treatments, 8 Levels Whiter in 1 Week - Image 1](https://m.media-amazon.com/images/I/71ZBgm6fZ+L.jpg) ## Available Options This product comes in different **Size, Flavor** options. ## Questions & Answers **Q: What is the per centage of peroxide** A: Hydrogen Peroxide 9.5%. Compare to 10% for {Professional Effects, Vivid, 1 Hour Express}; total amount of peroxide on each strip also matters. **Q: Can you drink coffee while doing this? Or do you have to give up the yummy caffeine?** A: I'm afraid it's a bad idea to drink coffee while using the whitestrips. I for instance only use them once a week, but as I can't and don't want to give up coffee, I always brush my teeth right after I've had my last sip (literally!). **Q: does it hurt** A: This is very individual dependent, but my wife and I did these prior to our wedding and I never went over the recommended time, whereas my wife would routinely go 20 min over. I never had any pain or discomfort; she would frequently mention sensitivity to hot/cold food. That said, her teeth sensitivity went away a week after finishing them. **Q: Must I use all of the pouches in order to see results? Or may I use a few and share the rest with someone else?** A: I saw results in my teeth after 3 days and even more after a week. If you're happy with your results after a week then you could definitely share. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great!

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. ## Frequently Bought Together - Crest 3D White Luxe Whitestrip Teeth Whitening Kit, Glamorous White, 14 Treatments( Each with 1 Upper/ 1 Lower), 28 Strips - Crest 3D Whitestrips, Supreme Flexfit, Teeth Whitening Strip Kit, 42 Strips (21 Treatments) - Crest 3D Whitestrips Sensitive At-Home Teeth Whitening Kit, 18 Treatments, Gently Removes 15 Years of Stains, Crest Whitestrips, Teeth Whitening Kit --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/668747-3dwhitestrips-1-week-smile-transformation-at-home-teeth-whitening-kit](https://www.desertcart.co.za/products/668747-3dwhitestrips-1-week-smile-transformation-at-home-teeth-whitening-kit) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-08-27*
