Don't know about the rest of you but I noticed that my teeth began to stain when I started drinking Bourbon 4 years ago to the point where I have them cleaned 3 times a year. At my last visit the dentist suggested I try Listerine White. She said one of her Scotch drinkers suggested it. I started using it 4 weeks ago and have been quite pleased with the result. It is a pre-rinse to brushing and not a mouth-wash. I have no investment in this other than wanting to pass it along. If anyone else has any suggestions I would appreciate it.
