My dentist said something similar, that flossing will pull a bunch of stuff out of my teeth. I never floss and on the rare occasion I do nothing comes out, maybe a little blood. I don't know if anyone else has experienced this, I don't really floss anymore though as it just feels like jamming string between my teeth for no reason. Never had a cavity or dental problem of any kind, in my mid 30s. Floss once a month maybe.

> Flossing never fails to extract some amount of food when I do it.

Now, prove that that amount of food actually does damage, and you have something.

Does halitosis count ? ;P

Yes. If all flossing does is cut down on the bad breath, that's still a benefit.

Wait, what? People can see stuff bring removed by flossing?

That has never happened to me, unless it’s something obvious like a piece of peanut skin that got logged in there somehow. Usually, the floss starts and ends looking pretty much the same.

The silky smooth PTFE-based floss doesn't, but the cheap store brand floss is rougher and does a much better job cleaning.

Me neither. Probably a genetic thing about the shape of the teeth. I don't notice a smell when I floss either.
