Do you think we are supposed to rinse with tap water after mouth washes like Oral B with cetypyridium chloride or Listering?
With Chlorihexidine it is clear that we do not. But for the above two it is not so clear. Their labels [At least for the Oral B one] says 'Do not swallow' which implies its not good to have them in your body.
Part of the value of a cetylpyridium mouthwash is the antiseptic value. This is wrecked by immediately rinsing with water, so I do the water rinse FIRST and the antiseptic rinse LAST.

I have to rinse my mouth after brushing with almost any kind of toothpaste, mouthwash before bed. My lips and mucous membranes just roll off with my fingertip in the morning from the chemical nasties they use in that stuff if I don't completely rinse after using!
