Dental Tip of the Month: Proper Flossing Techniques Flossing is an essential part of maintaining oral hygiene, but are you doing it right? Use about 18 inches of floss, wrapping most around your fingers, and leave about 1-2 inches for your teeth. Slide the floss gently between teeth, curving it into a C-shape. Don't forget to floss behind your back teeth! Your gums and teeth will thank you.
