Well, I have never tried the thread. The thought intimidates me too much! Like Everyone else has stated, you would really need three or four hands to do this process efficiently. Though, I can imaging doing it with two hands. First, you would need mint flavored thread. second, you would need a small model body like a model T, third you would need a large moutn! Place the body into the mouth and start to cut out the doros while flossing? HEHEHEHE. Jody
