Waterpik is an easier (and they would argue more effective) way to “floss” between your teeth, and Amazon is taking discounting the Waterpick Cordless Advanced Water Flosser to just $72 after you clip the $10 coupon (and the $80 list price is a pretty solid deal, even before the coupon). That’s a whole lot less than a visit to the dentist to fix a cavity.
