3D Whitestrips Professional Effects – Teeth Whitening Kit, 22 Treatments (20 + 2 Bonus), Each with 1 Upper/1Lower, 44 Strips – Crest 3DWhite Teeth Whitening Strips

I’ve used several at-home whitening products, and these Crest 3D Whitestrips Professional Effects are definitely one of the strongest options I’ve tried. Each treatment includes strips for both upper and lower teeth, and they stay in place well thanks to the no-slip design. You can talk and move around without them shifting, which makes the process easy to fit into your routine. The biggest difference with this version compared to gentler kits is the results—you start noticing a brighter smile within a few days, and after completing the full treatment, the whitening is much more noticeable. It does a great job lifting deeper stains from coffee, tea, and everyday use. Pros: Professional-level whitening results Noticeable improvement within a few days Stronger formula for deeper stains Strips stay in place well Cons: Can cause sensitivity for some users Requires consistent daily use (~45 minutes) Higher price compared to basic kits Overall: If you want stronger, more dramatic whitening at home, this is one of the best options available. Great for tackling deeper stains and getting close to professional results. TIP-If you experience sensitivity, skip a day between treatments or use a sensitive toothpaste during the process.

Crest strips absolutely WORK if used consistently! My teeth are very noticeably whiter by the time I get to the end of the package. Definitely worth the price. They also do not cause sensitivity for me as long as I use as directed. I did accidentally fall asleep with them on once and I do not recommend. Otherwise, fantastic product!

Finally found something that actually works for my coffee-stained teeth! Okay, so I'm one of those people who can't function without my morning coffee (sometimes afternoon coffee too, let's be honest). Add in the occasional glass of red wine, and my teeth... well, let's just say they weren't exactly photo-ready. I've been down this road before with whitening products. Tried those messy gels that never stayed put, those pen things that felt like I was coloring my teeth, and don't even get me started on the charcoal trend. Nothing really stuck or gave me results I could actually see. But these Crest 3D Whitestrips? Game changer. What you get and how it works The box comes with 44 strips total - that's enough for 22 treatments since you need one for top teeth and one for bottom. They're all individually wrapped, which is nice because I actually took some with me on a work trip. I committed to using them once a day for two weeks straight. And honestly? I was skeptical at first. But by day 4, I caught myself doing a double-take in the bathroom mirror. My teeth actually looked... brighter? By day 10, even my coworker asked if I'd gotten my teeth professionally done. The difference was pretty dramatic - maybe 2 or 3 shades lighter. Even some old stains from my college years (when I drank way too much coffee) seemed to fade. The actual experience Using them is pretty straightforward - peel off the backing, stick them on, wait 30 minutes, then peel them off. The strips actually stay put, which was a pleasant surprise after dealing with other products that would slide around. They're thin enough that I could still talk normally, though I probably sounded a little funny. I usually just put them on while catching up on Netflix or scrolling through my phone. The only downside? Around day 6, I started getting these little zings of sensitivity in a couple of my teeth. Nothing unbearable, but definitely noticeable. Switching to Sensodyne for a few days helped a lot. If you've got sensitive teeth to begin with, you might want to do every other day instead. Random tips I learned the hard way Dry your teeth with a tissue first - the strips stick way better Don't brush right before using them (learned this one the painful way) Keep them somewhere cool - I left mine in my hot car once and the adhesive got weird You get 8 extra treatments beyond the 14-day program, which is perfect for touch-ups Bottom line Look, I've dropped serious money on professional whitening before, and honestly? These worked just as well for a fraction of the cost. Are they perfect? No - the sensitivity thing is real, and you do have to plan around that 30-minute commitment. But if you want results you can actually see without breaking the bank or sitting in a dentist's chair, these are legit. I'm definitely ordering another box for maintenance - probably every few months or so. The good stuff: Actually works (saw results by day 4) Easy to use once you get the hang of it Strips don't slide around like other brands Way cheaper than professional treatments The not-so-great: Some tooth sensitivity (but manageable) Half an hour is kind of a commitment Can't drink anything while wearing them Hope this helps if you're on the fence! Happy to answer questions if you have any.

These Whitestrips do what they’re supposed to do: they brighten your smile and leave your teeth looking noticeably cleaner after a full round of treatments. The strips stick extremely well — almost too well — so once they’re on, they’re not going anywhere. That’s great for keeping them in place, but it also means you’ll feel them gripping your teeth the whole time. The whitening effect is solid, especially for an at‑home kit, and the strips stay put without sliding around. Just be prepared for that strong adhesive feel when you take them off. Pros: Noticeable whitening results Strips stay in place the entire time No slipping or sliding Cons: Adhesive sticks very firmly to teeth Removal takes a little patience

Buen valor

Al día 10 ví mucho cambio. Quedé muy contenta. Compré otros 2 para la familia.

De verdad notas la diferencia al usarlo

No pude ver los resultados dado que a partir del segundo uso me provocó hipersensibilidad y las dejé de usar.
