[quote=davidcpa] I also remember asking if my Listerine mouthwash could have caused it and they scoffed at my suggestion and went back to their typical patient description. [/quote]

David.. I had the exact same questions. After wading thru my family history, they "think" that mine was cause by genetics, simply because I didn't fit the "ole fogies" profile either. To me it seems this article has probably nailed these types of mouthwashes as a possible.
