Leaves a slight smell but not too bad
I wear a mouth guard every night and after getting strep that kept coming back, I wanted to get something that would hopefully work better than just brushing the guard but also wouldn’t damage it. I cannot say I noticed anything besides a faint smell on the mouth guard after using this sanitizer. I tried it on my old retainer that had buildup on it and maybe I haven’t used it enough, because I haven’t noticed any difference there either. I guess at this point I’m just hoping that it is doing what it’s supposed to when the little UV light goes on. Overall it’s not a bad case though.
