““Ideally, your floss [should have] key toothpaste ingredients in it,” Hoss says. “That's actually where most of the cavities occur — between the teeth.” If your floss doesn’t have ingredients built in to care for your teeth, Hoss says you can dip your floss in your toothpaste too. This SuperMouth floss is free from harsh chemicals, artificial colors and flavors. It’s also formulated with nano-hydroxyapatite, vitamins D3 and K2, plus fluoride to strengthen teeth. Or you can grab a fluoride-free version, but they are all available in Mint, Chocolate, Strawberry and Vanilla flavors.”

This cleans between my teeth very well. Better than other floss I have used in the past.

Cleans great, no flavor
Love how well this product cleans! I’m a dental hygienist and I bought this product to see if it was something I could recommend to patients. It doesn’t shred too much. I just wish it actually tasted minty. Public Reply (Supermouth)

Flossing with braces is hard! This flosss makes it so much easier. I love how the end is firm to get between the teeth. I now look forward to flossing.
