For awhile I was being really bad about my oral hygiene and not taking it nearly as seriously as I should have been, but here lately I've been much more on top of it and have been making sure to both floss and brush twice a day. If I don't do both twice, I make sure to do them both at least once.
If you've been neglecting your mouth health for awhile, if you start to take care of things as they should, the difference in how they (and you) feel will be really surprising.
Your gums should not bleed from either flossing or brushing and if they do, I'm pretty sure that's a sign of poor mouth health. After a few days of proper care, they shouldn't bleed when you do either and you'll love how much stronger your mouth will feel.
