is it possible to floss to often?!

You should floss once daily before bed. Floss gently but thoroughly. It is possible to slowly wear the softer enamel beneath the gumline if you floss too much or too vigorously.

Used to work for a dentist.

You need to floss at least once a day. I do it twice and no you can't do it too much. String can't damage your enamel.

you can damage the gums. So yes it can be.
