    It makes sense if you think about it. The flouride needs to rest on your teeth to harden them properly.

      I’ve updated my comment. I wouldn’t have intuitively thought about this because why would I think that it would take time for Fluoride to take effect, or that whatever is left after rinsing wouldn’t do the job? Thanks.
