🏆 Best Manual Flossers for Oral Hygiene
CNN Underscored
““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.”
