Review (4/5): A nice standard wipe for just about anything you'll put in your mouth
I don't have a retainer, but I do have a nightguard and I figured that since it's made out of the same stuff you'd see for some of the mouthguards and the like out there, why not give it a try? I'm always a little leery of brushing since I don't want to ruin my brushes or potentially harm my nightguard. Soaking it in some mouthwash is helpful, but then that isn't the same as a thorough clean.
The taste of this is fairly nice. I like that it's not extremely overwhelming. You can wipe your guard down and it won't be insanely strong. There will be a hint of flavor, but overall it's not going to be anything that will knock your socks off. This might be disappointing for some, but it's still a better thing to taste than the alternative. If you have a guard of any type, you know what I'm talking about.
This will get into most of the crevices and areas of the average guard. You'll have to cram it into the more small areas, but it will fit everywhere. It seems to do a fairly good job of cleaning as well. I'd read that it could help get rid of stains and other discolorations, which is the biggest thing that appealed to me. So far I've done a few cloths and it seems to be helping a little. It's not a miracle worker, but then I wasn't expecting it to be and to be honest, I'd be more than a little leery of something that would remove all the yellowing immediately. After all, what would it do to your mouth afterwards?
This is a pretty good option and I'm curious to try the soaks to see what they would do as well.
