Do you brush, then floss? Or do you floss, then brush?
I was thinking about this recently. We're all told to "brush & floss", which makes you think you should do them in that order. But...
If I've got something in my teeth that brushing doesn't get out, but flossing removes, now I have an area of the tooth that hasn't been brushed because obviously the brush couldn't get to it.
So I'm thinking it's better to floss first, then brush second.
