When I went to the Mikveh I noticed that on the
Mikveh preparation paper it is written that one should use unwaxed dental floss. I always use waxed, since I can clean my teeth much better with it, but was confused, so I asked the
attendant. She did not know but gave me the unwaxed one which everyone uses there. With it I could not clean my teeth very well, but I used it nevertheless since it looked more kosher. Is waxed floss considered a
chatzitza? And what about the fact that i cannot clean my teeth with it so well?
