Opalescence Go 15- Prefilled Teeth Whitening Trays - 15% Hydrogen Peroxide - (10 Treatments) Made by Ultradent Products. Teeth Whitening Kit -Mint - 5194-1

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.

This is the best whitener that I have found. The taste is okay, and it gets the job done. I think it is a little pricey, but it is my first choice. I feel that it is a safe product.

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.

I was thrilled with the results I got from using this product. I’m so used to hair and skin products that don’t really deliver on their aesthetic promises. But this product actually made a visible difference and made me less self-conscious about my teeth. It caused slight sensitivity that lasted for a day after each use. I found the sensitivity wasn’t as bad as Crest white strips.

Works great! This keeps your teeth white for a quite a while. Using a tooth whitening toothpaste helps maintain the whiteness.

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!

I got the 10 and used it for 10 days. I definitely noticed a difference in how white my teeth are, but they’re definitely still not white. I didn’t have any sensitivity to them. They’re very easy to use as well. One of the trays did come squished however, making it difficult to use.

These work well!! I drink coffee and stains are removed! Will buy again!
