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

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 stains, and 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 can cause a little sensitivity if I use 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. 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.

I was honestly skeptical at first, but this kit worked better than I expected. I noticed my teeth starting to change around day 6-7, and by the end of the treatment my teeth looked visibly brighter and more even in color. I also had no problems with sensitivity, which was one of my biggest concerns. The trays were easy to insert and comfortable to wear. Overall, I was satisfied with this whitening kit and would buy it 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.

This was a really great product. It whiten my teeth a significant amount with just using 10 trays. It was a noticeable difference. The only downfall is that I have very sensitive teeth so I can only whiten my teeth to 30 min. I accidentally forgot my trays were in and I had them in for 40-45 min and the day after I was really sensitive but not an unbearable amount. I am definitely buying again

They work just fine, as they contain the active ingredient to whiten teeth. The delivery method is infuriating as they don’t stick to teeth like they are supposed to and you have to fish the trays out of their outer holder and put them in. The gel is sloppily distributed on the trays and seems like it would work unevenly on teeth. I’ll stick to 48 pairs of white strips for the same price.

By far the best whitening product I’ve found. It turns out smile into a brilliant one.

I was looking for teeth whitening that was cheap yet effective and this is it. At less than 10$ a treatment (on sale) and 10 treatments its honestly a steal. I would say 2-3 of them got me to have white teeth and paired with regular brushing I am able to maintain that white rather well. I had to give a few away to my gf and friends just cause I couldn't believe it so I'll have to buy another otherwise I could see this lasting me years.

I saw on some YouTube videos that this product was recommended by several dentists and orthodontists. I tried it and then saw how quick and effective it worked. My gum became a little sensitive after 9 days so I spaced a few days between application and it was much better. After 6 months, the whitening effect is still there. I would like to do it again to make them even whiter.

Turns out every toothpaste and whitening product I have used is entirely unimpressive and has zero lasting effects. This on the other hand kind of shocked me at it's intensity. Yes--it is painful sometimes, so make sure the trays are in place precisely and coating your teeth instead of your gums. It might cost $120 but honestly, just buy it when you can afford it.Having white teeth is just honestly such a confidence boost and I don't have to be shy with smile because of my teeth. I can't put a price on that. If your job or social life or dating life depends on you being professional--just go with this 100%
