Two clinical studies (1, 2) have shown that using Listerine twice a day is as effective as flossing your teeth once a day. Of course both were sponsored by Pfizer, makers of Listerine, but they wouldn’t make a claim like this if it weren’t true.
Of course, Pfizer says you shouldn’t stop flossing, but that’s just to cover their asses. I say we all stop flossing and start swishing!
Nobody has time to floss – but everybody can swish some liquid around in their mouth for 30 seconds. It’s easy!
