LOVE LOVE LOVE! Best whitening product I have ever used. I would purchase these again 1000%! I got my first set on sale and hope to get the next the same way when I need them. The sensitivity issue wasn't bad at all for me. I have had much worse with other store brands whitening strips. My teeth are noticeably whiter after the entire box used, and I drink coffee, tea, and smoke currently.

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’m giving this 4 stars for now and plan to come back with an update after I’ve completed more treatments. For context, I’ve only used one tray so far, so I can’t speak to dramatic whitening results yet. After one use, I didn’t notice a huge visible difference. In the past, I’ve used the Snow whitening system and Crest whitening strips, and I feel like I noticed a more exaggerated one-time brightening effect with those. However, the reason I wanted to try Opalescence Go 15% is because I’ve gone through two LED lamps with my Snow kit and was tired of replacing them. And based on my research, Crest strips aren’t always the best option for gum and oral health long term. These trays are widely recommended by dentists and seem to be a safer, more professionally backed option overall. I also considered professional whitening, but with a $500+ price tag, I wanted to give a high-quality at-home system a fair shot first. My teeth aren’t heavily stained, but daily coffee definitely leaves its mark. What I love about these: • Super easy and completely mess-free • Prefilled trays = no gel measuring or cleanup • Only 20 minutes for the 15% formula • Pleasant mint flavor that isn’t overpowering • Zero pain or sensitivity, which I almost always experience with whitening products The only downside so far is that I didn’t see a dramatic difference after the first use. That said, I know whitening is often cumulative, so I’ll continue using the full set and update this review with longer-term results. Overall, if you’re looking for a dentist-recommended, easy, and comfortable whitening option, this feels like a solid choice so far.

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.

For many years I've used Crest Whitestrips or store brand knockoffs, and have never been satisfied with their performance. I thought strips were the only surefire way to whiten teeth at home aside from applying gel directly to your teeth, until I began see more and more whitening tray products in sponcon from Instagram influencers. They shamelessly promote trays and UV thingys that are well over $100, luckily I found these instead. Honestly these trays are so good for the money that I can't possibly recommend saving $30 to purchase Crest Whitestrips. Pros: Incredibly easy to put on - Put a tray on your teeth, bite down, and suck. That's it. Getting Whitestrips to stick on both sets of teeth can be a struggle, these are easy. Coverage is great - The bottom tray is probably double the width of a Crest Whitestrip, They stick to your teeth - I did not have issues with these slipping off. They don't even cause excess salivation. It's the polar opposite for Whitestrips. I'm constantly spitting out saliva trying to keep my teeth dry enough so the strips will stick. And the bottom strip never stays in place. 15% hydrogen peroxide - This is more than double the 6.5% peroxide in a Crest Whitestrip. You get superior whitening in the same amount of recommended time. Only need to use 2-3 trays at a time - You can get noticeable results from 2 trays and save the rest. Whitestrips require at least a week's worth to notice a real difference. Not only are these easier to use, they are more cost effective due to the design and higher peroxide content. Cons: Only one con, you will have to scrape hunks of goopy gel off your teeth after you remove trays. Not really a big deal, just make sure you take them out while you're at a sink.

I haven't used a tooth whitener in years. I haven't had home or professional whitening in nearly a decade, and I have an important event coming up. My teeth look exactly like the teeth of someone who drinks lots of coffee, and I'm beginning to feel self conscious. So I read the reviews and decided to try this. I saw a difference after twenty minutes. I'm genuinely surprised. This took years off my appearance. My teeth are very white next to my tan...and before my tan and my teeth just sort of blended together. I kinda can't believe it. I still have nine packs left, and more than two weeks before my event. My teeth should be proper pearly by then!

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.
