A certain famous breand name mouthwash is very very unpleasant to use. Uncomfortable is an understatement. Another one which is a well-known "natural" brand stings a teeny tiny bit so it is far more pleasant to swish around in your mouth. Does the very uncomfortable one do a better jo protecting you than the one that isn't? I'm not mentioning brand names but I'm pretty sure the cognoscenti among you know to which I refer.
