These whitening strips actually worked on my coffee-stained teeth
By Amazon Customer on Reviewed in the United States on June 5, 2025
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.

It made my teeth sensitive
By Masiha on Reviewed in the United States on October 26, 2025
It was working but unfortunately made my teeth so sensitive that I couldn’t open my mouth to breathe! I had to take medication to relieve the pain specially my lower teeth. That’s unfortunate because it was working and I liked it but I had to stop and return it.
