I like Listerine...but rarely use it cause it's more expensive than the Colgate...
Odd. I never knew that fluride was in fact bad for teeth after a certain point. I have 2 implants and had braces, during those periods I often was prescribed a mouthwash which was pretty much fluride...
My teeth do not have any sort of discoloration that fluride seems to cause, so I suppose it wasn't all so bad.
