My Listerine mouthwash bottle directions says that for best results use twice a day after brushing. My toothpaste has 1450ppm fluoride, whereas the mouthwash is only 450ppm. Won’t using the mouthwash afterwards simply wash away the higher, more beneficial levels of toothpaste fluoride and replace it with lower mouthwash levels? What’s the reasoning for this advice?

Brushing will loosen up material from your teeth using mouthwash after brusing helps get the loose material off your teeth and out of your mouth.
Also, mouthwash will cause your gum line and tounge to be sensitive for a while after use and can make brusing those area hurt.
