I started flossing my teeth every day during university I think. I realized these are the only teeth I’ll have for the rest of my life (and I plan to live for quite a while!)
My gums bled each time for a couple weeks perhaps, but they never bleed now. I can floss without looking in a mirror; I know the exact feeling of each spot.
HOWEVER, though I floss every day, my dentist says there’s still some tartar accumulation so it’s not a magic never-see-dentist-again lifestyle, but it sure helps!
