I quit smoking forever sometime back, but tobacco stains are still there. Though they are getting less darker since I quit. But still lot of them remain.

I read somewhere that Flossing removes stains. But someone told me that it only HIDES and not remove stains, so one has to do it repeatedly which eventually weakens teeth/gums. Is it true?

Also, please suggest some methods so that all stains go away forever. Kitchen methods are also welcome.

On the funnier side, I cant stop speaking and keep quiet!
