Leaves my nightguard clean and minty fresh!
I use a nightguard and it was getting nasty, regardless of how much I cleaned it. This took a lot of the discoloration off my nightguard and it leaves it with a minty fresh taste. I leave it soaking from the time I get up, until bed, once a week and it leaves my nightguard fresh and clean. Highly recommend!

Good cleaner for night guards
I wear a night guard because I grind my teeth. This keeps my guard clean, with no aftertaste. Does not turn my guard any color. one tablet daily, so this package will last you 4 months.

Good for night guards
Seems to work well. Just got a new night guard from my dentist and want to keep it from turning yellow like my last one did.

Effective, but expensive
This is fine retainer cleaner. I've been using it with my night guard for the last three nights, and it clearly works very well. I drop my retainer in a container in the morning, add one of the individually packed tablets and hot water, and the retainer is ready for use in the evening--or long before that. No film, no residue. Perfect. It's hard to tell how it compares to the other retainer cleaners that I have used--all of which seem to work well in cleaning and removing bacteria. The principal ingredient in this cleaner is sodium bicarbonate. So, it may be a bit gentler that some of the others. My dentist told me to brush the retainer with toothpaste rather than soak it--advice that I ignored. It's possible that a gentler retainer clean could prolong the life of the retainer. But I can't check this out, nor can I say whether this cleaner really does eliminate 99.9% of the bacteria on the retainer--though it's likely that it does. What I do know for sure is that this cleaner is twice the price of the Efferdent that I get at my local supermarket and more than the store's generic brand. It may be better, but I can't tell.

Bought these to clean my Invisalign trays and they work great. I use them once a week for a deep clean. Keeps things from getting gross.

Easy to read instructions. I got this for daily cleaning of my Clear Aligners, and they do an amazing job removing stains, brightening the trays, while leaving a fresh scent.

The taste of the cleaner is minty-ish. Better than other cleaners I’ve used

I had my retainers for 2 years before trying this cleaner out. Overall, it works fast. My retainers were foggy and after the first day, they were clear again. However, this cleaner doesn’t do too good at getting off the built up stuff. I’ve been using this cleaner for about 11 days and there’s still gunk on my retainers. I can see it slowly going away, but if you’re looking for a fast fix, I’d recommend trying another cleaner.
