Reach Mint Waxed Dental Floss is a brand I have used for many years. I like it because it slides easy between my teeth, and doesn't snap easily at rough spots. Any particles of food fly rapidly out and onto the mirror if I am not careful. After I floss with Reach, I brush my teeth and find them to be as clean as a dental prophylaxis, and consequently I do not need to visit the dentist as often. The mint flavor is pleasant and keeps my breath smelling clean. Overall, if you want to keep your teeth, keep flossing!
