Why does mouthwash recommend being used after brushing, when it has lower ppm fluoride than toothpaste?

1.36K viewsOther

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?

Every time I go to the dentist, they say what I’m doing is wrong. Mouthwash before. Mouthwash after. Interdental brushes before, interdentals after. Brush this way, brush that way. Slaughter a chicken – oh no wait slaughter a goat.

I’ve come to the conclusion that it’s all utter bollocks. I don’t worry about it any more. I do what I think makes most sense, then just nod along with them. 

Mouthwash, electric brush, interdentals, don’t rinse. If that’s wrong then it’s wrong.
