Crest 3D Whitestrips Professional Effects really deliver noticeable results. After just a few treatments, I could see a clear difference in how much whiter my teeth looked, and the results continued to improve with consistent use. The strips are easy to apply and stay in place well during the treatment time. I experienced very minimal sensitivity compared to other whitening products I’ve tried, which was a big plus. The kit with 22 treatments feels like a great value and allows you to maintain results over time. Overall, this is one of the most effective at-home teeth whitening options available. If you’re looking for professional-looking results without going to the dentist, these are a great choice.

I've worn Crest white strips about once a year for decades. I had my teeth whitened professionally after my normally white teeth inexplicably become sort of grayish tinted when I was in my late twenties. (And yes, I know they say you can't whiten gray teeth but I guess I'm an exception). I then started using the Crest White strips annually to maintain my white teeth. I had always been happy with the results until last year when I got a dud version even though it was one of the more expensive versions and it said to only use it once a year, whereas the usual advice on the Crest White strips is that you can use them twice a year. I took the once a year recommendation to mean that it would be a stronger formulation then the typical white strips. It was actually my worst experience with white strips by far. There was very little improvement. So this summer I bought white strips with some trepidation, even though this version has a bazillion five-star reviews. I was wondering if it was the white strips that I had problems with last year, or was it maybe that I was getting older and my teeth just wouldn't get as white. Well, the answer is that my teeth will get white with good quality white strips like these 3D professional effects strips. The two days of the more powerful whitening strips that are in the package does a good job of jump starting the whitening. My results were excellent and the results are maintaining well 6 weeks after I finished the strips. Details: I don't have much problem with sensitivity but if I do, I try to brush more gently, and I might skip a day. I use a whitening toothpaste in the morning and a gentle toothpaste at night. I don't use mouthwash for the duration. I avoid food and drinks that stain my teeth except for coffee in the morning. You might want to do some research because a lot of food and drinks that you might not suspect actually do stain your teeth. An example is some clear sodas. Even some toothpastes stain your teeth. You can actually find that statement on some very ordinary, major brand, mainstream tubes of toothpaste! I wait 30 minutes after eating or drinking in the morning and then floss and brush my teeth. I then wait a solid 30-40 minutes before using the white strips. After I've used the box of white strips, I go back to using the Crest whitening mouthwash and the same whitening toothpaste in the morning / gentle toothpaste at night routine. In my personal experience, the mouthwash doesn't do much to whiten teeth, but it is very helpful in maintaining white teeth. Be sure to follow the directions and don't eat or drink for 30 minutes after you have swished with the mouthwash for 1 minute. Try to swish with some water afterward if you do eat/drink foods that stain teeth. Maintain brushing twice a day. This really is a difference-maker for me.

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.

The results with these strips were noticeable, my teeth definitely looked brighter after a few uses. They stay in place well and are easy to apply, which makes the whole process pretty simple. The only downside for me was the sensitivity. By the third or fourth treatment, my teeth started feeling a bit tender, so I had to space out the applications. The whitening still worked, just needed to go slower than recommended. Overall, they’re effective if you want a quick boost in brightness, just be mindful if you’re prone to sensitivity.

I’m really happy with these strips. They actually whiten my teeth in a way I can see, and they don’t leave my teeth feeling sensitive afterward. I’ve tried other whitening products that made my teeth ache, so I was nervous, but these were super gentle. After a few uses I could already see a difference. Easy to apply, they stay in place, and the results are worth it. I’ll definitely keep using them.
