Is flossing necessary?

Flossing is actually more important than brushing. It can add four years to your life span if you floss every day at least once.

I mean look... a lot of people don't floss. But realistically you very very much should, it's actually more important than brushing your teeth

like butt flossing?

Flossing is necessary, I floss properly, no rush.

Take care of your teeth and floss them.
