I’ve tried several teeth whitening products over the years, and this is one of the first where I actually saw a noticeable difference within just a few uses. It really helped lift my coffee and wine stains. My teeth look visibly brighter overall. One of my favorite things about this system is the built-in trays. They conform to your teeth really well, which makes them comfortable to wear and easy to use compared to strips that can slip around. Each session is only about 20 minutes, so it’s easy to fit into your routine. I didn’t find it messy, and the process feels pretty straightforward. The only downside for me is that it caused a little sensitivity if I used it too frequently, but it’s temporary and goes away fairly quickly. Spacing out uses has helped. Overall, I think this is a great option if you want noticeable whitening results at home, especially if you deal with coffee staining like I do. This is a whitening system that can be found in dentist’s office too. My dentist carries it. I’ll definitely keep using it to maintain the results.

My teen was recommended this by his dentist prior to getting veneers on a couple teeth affected by genetic tooth discoloration. Note that this product can be purchased at a dental office for a significant discount than the price here, it was only about ~$60. The results were amazing! Even the genetic discoloration was cleared up to the point we couldn't tell (without really inspecting) that he even had it anymore. We decided to forgo the veneers altogether, saving $3000! Only once during the process did he complain about tooth sensitivity, and that was only after he accidentally feel asleep with it on his teeth for over an hour one time. That sensitivity was gone by the next day. Note the product is available in 10% and 15% strength. Per the included instruction pamphlet, the 10% product should he worn for 30-60 mins and the 15% product for 15-20mins. We had the 15% version. I was so impressed (me=mom) that I got a package for myself. I had previously used white stripes several times throughout adulthood. These are at a totally different level!! Wow! Why are they worth double the price over white strip, you ask? The trays make applying them simple and less messy. One tray is marked for the upper teeth and one for the lower teeth. Bite into the tray, and viola!, the applicator containing the whitener (which is like a thin mouthguard) is on your teeth perfectly positioned. The tray is immediately loose and easily removed, leaving the applicator in place. The applicator is thicker and more rigid than white strips. It stays in place the entire time! Go ahead and spit if you feel the need, even an accidental cough does not dislodge it. It's a game changer...they stay in the right place the full 20 mins! Conversely, those white strips would slide around and probably ended up putting the whitener more on your gums and tongue than your teeth. After the required time, remove the applicator and the whitener gel will still be on your teeth, like thick clear paste. Wipe off with your fingers, wet towel, or gently brush it off. I have not experienced sensitivity at all, and I have very sensitive teeth to the point I get burns from any regular toothpaste containing SLS. To be extra cautious I do know from past white strip experience NOT to brush with an electronic toothbrush for about 30 mins before or after using white strips...or else suffer from the gums burning!...so I used the same precautions here too. No issue with burning at all. Needless to say we are huge fans and will continue to use for maintenance!

After trying the 15-day treatment, I’m genuinely impressed by how effective these whitening trays were. My teeth brightened by about two shades, and the convenience of doing it all from home makes this a standout option. 📦 Well-Packaged and Ready to Use: The trays come neatly packed and individually wrapped, keeping everything clean and easy to store. It’s clear a lot of thought went into the packaging—not just functional, but also a bit polished. 🧪 Powerful Whitening Formula: The whitening gel is no joke. It delivers noticeable results without causing the sensitivity I’ve experienced with other brands. Just be ready for a slightly funky taste—not exactly refreshing, but totally manageable and far from unbearable. 🏡 No Molds, No Dentist Visit Needed: The pre-filled trays mean you skip the hassle of getting custom molds or visiting the dentist. Just pop them in and go. It’s a simple, at-home solution that feels much more professional than most over-the-counter options. 🦷 Fit Matters—Bite Down Firmly: You do need to bite down with decent pressure to ensure the gel makes good contact with your teeth. If you don’t, the results won’t be as even or effective—so give it a proper bite and wear time. 💸 Pricey, But Cheaper Than a Dentist: Let’s be honest—it’s a bit expensive for a DIY remedy. But when you stack it up against the cost of an in-office whitening treatment, it's a clear win. You're saving hundreds, even if the upfront cost feels steep. 🎯 Final Verdict: If you want noticeable whitening without the dentist markup or mold drama, Opalescence Go delivers. The results speak for themselves, just be aware of the taste and budget. I’d recommend it for anyone looking to upgrade their smile at home.

Our daughter was getting married in three weeks! I had tried everything to help get my husbands yellow teeth white! This product really worked! It took a regular every few days the weeks prior and we used the entire box but, the results were amazing! So many family members commented! I actually got it for the bride and groom as well! Great results! My brother in law is trying it now too! White teeth for everyone!

I saw improvement in the color of my teeth after first use. Very easy to use. Fair price. I only use once a week. Will purchase again.

I’ve tried a lot of whitening products over the years like strips, pens, and a few different kits, and these have honestly been the easiest to use. The trays come prefilled, so you just open the package and put them in. There’s no mess and no guessing about how much gel to use. I used the mint Opalescence Go 15% trays for about a week and started noticing my teeth getting brighter pretty quickly. I was a little worried about sensitivity because my teeth can be sensitive with whitening products, but it was very mild and totally manageable. The trays are also more comfortable than I expected. After a couple minutes they kind of mold to your teeth and stay in place well. I could walk around the house and do normal things without feeling like they were slipping. The mint flavor is nice and fresh but not overpowering. By the end of the 10 treatments my teeth looked several shades whiter but still natural. It didn’t give that overly bright artificial look some products do. A couple people even asked me if I had my teeth professionally whitened. Overall I’m really happy with these and would definitely buy them again when I want to do another whitening round. They’re simple, effective, and way less hassle than a lot of other whitening products I’ve tried.

Have fairly crooked teeth, a small over bite - these were literally the worst and most difficult product i have ever used. I neglected to use them within the return window bc they were highly recommended by my dentist of all people. When i finally did use them i realized the product just didn’t work as intended for my teeth. I used the toothpaste before (even though that was only for sensitivity per the instructions). I placed the upper mouth piece carefully on my teeth and firmly bite and sucked for two seconds as instructed and the white didn’t suction as depicted - it didn’t suction AT ALL, the white film wasnt even fold, the gel hadn’t even moved. I figured id just suck on it until it WAS stuck. They NEVER stuck, they wilted a little but lifting off my teeth. I even tried a second one and it just wasn’t working. The second time the white paper was folding in on itself bc i kept trying to take off the green part and the white film wasn't even fold coming off with it so i place it back on and could see it was folding behind my teeth. This was honestly such a mess and was waste of my money. These are cheap. Its disappointing i want my money back

This is probably the best at-home teeth whitening kit you can get in terms of effectiveness. It really works if you follow the instructions to the tee. I removed two stars because they don’t keep well if you try to piecemeal each whitening tray. I usually have fairly white teeth as it is, but like to do one a day, for just a couple of days, to boost my teeth whiteness - then I save the rest for later, until I’ve used up all 10 in the box. When doing it this way, eventually, the inner white tray ends up sticking more to the outer green tray - so the white tray will not actually *stay* on your teeth when you remove the green tray. And when that happens after you’ve put it in your mouth, the white tray falls apart & yields a goopy mess (and a waste of money). So just beware, follow the instructions to the letter, and then don’t piecemeal them so you can actually get to use all 10 trays.
