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

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.

Whitens great. Easy to use. Did not make my teeth sensitive.

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.

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 love this teeth whitening!! My dentist was selling it for a higher price so I looked it up on Amazon and the price was so much lower. This is the very best whitening I have ever used. Try it!!

I first bought this oproduct from my Dentist office. It now is sold on Amazon for a bit less cost. It is a good product, easy to use and I have had good results. I tend to forget to use it on a regular basis, but even after one or two treatments my teeth are brighter.

I got these hoping they would be better than the strips I was using. I was wrong! These are terrible and I will not be rebuying. Firstly, there’s more to these than just the strips. With the strips, you peel them off, stick them on your teeth, and wait the amount of time. Easy. With these trays, you have the main plastic tray, then the weird waxy tray that holds the whitener. You have to push the main tray on and kind of suck the waxy tray onto your teeth. It always takes me several rounds to really get the waxy tray to stick and it feels like a sports teeth protecter when they are in. On top of that, the whitener inside the waxy tray is clumpy and I almost wondered if it was old/expired but the box didn’t have a date that I could find. It should be like a toothpaste and kind of squish around your teeth, but every time I take these off, there are clumps on my teeth and the stuff doesn’t seem to be spreading appropriately, which reduces the whitening effect of the product. I noticed spots on my teeth where the clump balls would be and would whiten in spots. Also, these are designed for perfectly straight teeth. Now, I don’t have crazy crooked teeth, but I do have one, on the bottom row that is not perfectly aligned. I’ve never had any issues using strips, but these trays don’t work well at all. The top row fits okay and seems to stay once you manage to get it on there. But the bottom row never fully covers that one tooth that isn’t perfectly aligned, and it slides around on my bottom row very badly and doesn’t whiten evenly. Overall, the Crest brand whitening strips whiten better, stick better, and are cheaper than these with less hassle and less overall waste.

I am not sure these are working our not. I wanted to whiten my lower teeth as I am getting a bridge that I requested a shade lighter than my current color. I am able to use the uppers and lowers for my teeth so the box lasted me twice as long as a normal person. I don't know if it is because I am having a hard time applying them or just a bad batch. I bought another box to see if the shade gets better. They are very hard to apply. I dont know how many times that I have tried to remove the green tray just for the whitener to still be in it. I really have to press down hard everywhere and suck multiple times as well as wiggle it side to side to get the green tray to come off without the whitener. Very frustrating. My gums, also, are getting irritated from the clear tray that holds the whitener. It appears to be pushing down on my gums during the 15 minute or so time for application. As far as refrigeration, my dentist said that is only for if you are not going to use them for a while. If you are going to use them within a month or so, refrigeration is not necessary. I know there is a question as to 'well how long did they sit in my doctors office or at an Amazon facility' which I cannot answer.
