I voted that I'm not sure and haven't thought about it before.

I go to the dentist every 6 months for a cleaning thats about it. I used to have alot of cavities due to drinking SODA! But yea, I guess since I quit that I haven't had that much. And I floss, brush, and use listerine and plax regurally so... my teeth are fine...

Only complaint I have is that it sucks even more to floss now because of all the MEAT that gets stuck in my teeth.... eww.

Oh yea, and as for "morning film" the only time I have EVER gotten anything like that was if I don't brush and floss before I go to bed.... I can't stand going to bed without doing that.
