reliable cleaner that works consistently well

Yaniv.FJanuary 25, 2026✓ Verified purchase

I’ve bought these retainer cleaning tablets multiple times now because they’ve been consistently effective. They dissolve quickly, clean thoroughly, and leave retainers looking clear without any residue. The tablets remove buildup reliably, and the difference after each soak is noticeable. The scent is mild, and the solution doesn’t feel harsh on the material. I’ve used them on both clear retainers and a night guard, and they’ve worked well for both. The tablets are individually wrapped, which makes them easy to store and use without worrying about moisture getting in. If there’s anything to note, it’s that very heavy buildup may need a bit of brushing afterward, but for regular maintenance these tablets do exactly what they should. Overall, they’re dependable, easy to use, and effective enough that I keep coming back to them. Read more

I was skeptical, but this truly works great!

MaryAnn PomeroyFebruary 18, 2026✓ Verified purchase

I have to use a night guard for clenching my teeth, and no matter what I do or how I clean it, it always has an unpleasant odor. I've followed my dentist's instructions on cleaning it, and I've tried soaking it in hydrogen peroxide, vinegar, and drug store denture cleaning tablets. Nothing worked. But after just one use of this product, the smell was gone! Even after using my night guard overnight, when I woke up this morning (after soaking it before bed last night), I could still taste and smell the minty fresh clean smell instead of the usual morning odor! I couldn't be any happier with this product. I am so pleased by the cleaning power, the value, the ease of use, and the amount of tablets in the box. I will definitely be a regular customer from here on out! Read more

Cleans so well! Barely need to scrub afterwards

The Noll GirlsDecember 29, 2025✓ Verified purchase

My daughter’s retainers for her mouth get extremely dirty. These retainer cleaner tablets for her Invisalign and nightly retainers. Work wonders. They are so easy to use, every morning. I have her fill a glass with warm water, dissolve a tablet in it and then add her mouthpieces in it. Most of the time by lunchtime they are cleaned without any scrubbing needed. Sometimes we will wait for the blue water to turn clear again and then take them out give it a little rub for a couple seconds and they are like new. They have a fresh slightly minty smell to them, so there is no lasting effect when you put it back in your mouth when they are clean. We use them a couple times a week. The box lasted a very long time. Read more

Amazing

AmandaJuly 9, 2025✓ Verified purchase

Short version: These are amazing and saved me from spending $100 on new retainers I rarely give five stars but these tablets are actually amazing. I've been wearing a plastic Invisalign style retainer at night for years and I'm not sure if I could reorder replacement retainers from the same place I got the original ones, over the years my retainers got so disgusting that I was worried I would have to pay $100 for a new set, if it would even be possible to get replacements. I tried everything - soap and warm water, dish soap, even an ultrasonic cleaner. Nothing worked. These tablets are literally the only thing that have ever worked on cleaning my retainers. My retainers were starting to get a grayish yellow tint and there was what almost looked like plaque buildup around some of the gum lines. I threw my retainers into a glass mason jar with warm water and two of these tablets the first use, and I would say sitting throughout the day, two tablets cleaned about 50% of my retainers. Which is amazing considering they had not been adequately washed in about 2 years. Nothing else removed stains or crud buildup and I was disappointed that I would probably have to throw my retainers away and get a new set (which might have even meant an orthodontist visit to get new molds). Two days in a row of doubling up these tablets plus warm water literally made my retainers look brand new after years of disgusting buildup. And yes, I brush my teeth before bed and before putting in my retainers. Build up happens. But these tablets are legitimately awesome and I use them every day now. If you wear retainers, you should consider these tablets a necessity just like toothpaste and a toothbrush. Parents of kids or teens who wear Invisalign or nightly retainers, please buy these for your kids. Pros: + Tablets and packets are a good size. They come in sleeves that you can tear apart if you want a smaller storage size. + Super easy to use. Add warm water to a container, open one of the packs, and throw a tablet in the water. + Affordable (I know spending $15 or $20 on retainer cleaners might seem silly, which is why I put off this purchase for months, but keeping your retainers in good condition will save you the money of replacing/buying new retainers) + There are a lot of tablets in each box, each box comes with multiple sleeves and each sleeve has multiple tablets. It's basically a rectangle sleeve with six tablets and a perforation between each tablet, so you can break these down into single serve little pieces if you need to throw one or two tablets in a toiletry bag or your purse. You don't have to store the sleeves in the box if you don't have space. Cons - Nothing really Read more

Great for Daily Cleaning , But Not for Thick Plaque

IrisssssNovember 20, 2025✓ Verified purchase

I’ve been using these tablets every night for about a month, and they’ve made a big difference with my retainer. It doesn’t smell anymore, it looks clearer, and the surface feels smooth instead of gritty. My routine is simple: dissolve one tablet in warm water, let the retainer soak while I get ready, rinse, and done. Super easy. What I Like: No more bad odor Easy to use Looks cleaner and feels smooth 120 tablets last a long time Important to Know: If your retainer has heavy plaque buildup or old stains, this won’t completely remove it. You’ll probably need something stronger or a professional cleaning. But for daily maintenance, it works really well and keeps everything fresh. The smell when the tablet dissolves is a bit strong at first, but it doesn’t stay on the retainer afterward. Read more

Keeps retainers fresh and clean

FM findsDecember 13, 2025✓ Verified purchase

These tablets are easy to use and do a great job keeping my retainer clean and odor-free. With daily use they help prevent buildup, and the large supply lasts a long time, though you do need to stay consistent for the best results. The tablet size is great and fits perfectly in a small cup. I wear my retainers every night. They are very effective. Read more
