notice at 3min 33 s, the index finger position is good for flossing the posterior teeth.
Note: slight bleeding may occur for a few days if you haven't floss for sometime before that. This is due to dirty gums. Flossing will reverse it. If it persists however, do see a dentist.

Infection of the gums are like infections of the body elsewhere... Why do we have the notion that it's less serious and important?
Is it cos it's not as obvious as the lesion on your arm?
Pay respect to your mouth, not just with food, but with a daily spa and 1/2 a yr dentist's touch.
Cheers.
