This worked for me. It actually whitened my teeth at least 4 shades. The gel is thick and doesn’t distribute evenly. I had to press downward for my lower teeth and upward for my upper so the gel would spread. That’s my only complaint. It was a bit tricky to get consistent results. The first half felt slow in terms of seeing the whitening. On day 6 and on is when I saw it building each day. I had very low sensitivity to this. I use a tooth paste for sensitivity and I believe that helped along the way. At some point I’m going to do a second round.

I've used different whitening products over the years, and what I like most about these is how easy they are to use. There is no gel to measure out, separate trays to fill, or much preparation involved. Everything is already portioned in the trays, which makes the whole process much less annoying. The trays took me a few minutes to get used to the first time, but after that I knew what to expect and found them pretty comfortable. The mint flavor is noticeable without being overwhelmingly strong, and I didn't have an issue with a horrible chemical taste lingering in my mouth afterward. After several treatments, I could definitely see that my teeth looked brighter. The change wasn't an unnatural, blinding white overnight, but there was enough of an improvement that I noticed it when looking in the mirror. I actually prefer having the whitening happen gradually rather than looking drastically different after one treatment. Sensitivity is usually my biggest concern with teeth whitening. I did notice a little sensitivity at times, but nothing that made me want to stop using them, and it was considerably more manageable than I've experienced with some other whitening products. These are definitely more convenient than most whitening systems I've tried. Having ten individual treatments ready to go makes it easy to keep up with, and I've been very happy with the results.

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.

Love love love these. I’ve bought them like 4 times off Amazon already. Yes definitely expensive but they also give amazing results. I prefer them over crest strips personally. The taste isn’t bad at all if you get it in your mouth, the gel is definitely not my thing but I just brush as fast as I can when I take them out to get it out so it’s not that bad.

I do recommend! I’ve used this product many times. It doesn’t give you sore/white gums like crest white strips. I used all 10 trays in about a 14 days span. I had to take a couple days off because it made my teeth sore. But I feel like I see progress. I usually use about 5 trays once a year to maintain, but got behind on my whitening.

These are awesome! They work beautifully, quickly & the tray goes farther back to get more teeth whitened so it looks more natural & clean white. It’s easy to use & my dentist recommended them! I’m super happy with my purchase!

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.
