Too big!
I have a problem with buildup behind my lower front teeth.  Judging by the photo, this would have let me use the polish in that location.  When I received the polisher, I was dismayed to find it's not at all what is pictured!  The head of the device is far too large to fit inside my mouth.  I think it would work fine to polish the outer sides of your teeth, but there is no way it would get inside for the inner sides.  Sad panda.
