Review (5/5): Great when you can't see the dentist
I had some staining on my teeth from smoking, drinking, and my braces. I could not get the space behind the wire and the dentist schedules cleanings so far out it was driving me crazy. I found this on Amazon and it is great!! It was slightly difficult at first trying to figure out how to properly use it but once you get the hang of it, this tool is great!!
