I'm not sure if this had been discussed before, a simple google search seems otherwise.
Anyway, do you use mouthwash? What kind of mouthwash? In general it's separated into:
1. antiseptic (medical grade: chlorhexidine)
2. antiseptic (medicated oil based, e.g. listerine)
3. flouride (e.g. oral B)
4. ???

I'm using oral B once a while, and i'm considering if i should use listerine. i dont particularly have bad breathe, but docs tend to say my teeth are dirty.. even after floss/brush... lol

interesting link. thanks!
