Funny, I had heard floss then mouthwash because the flossing opens up more space for the mouthwash to get into.

But I think the chief thing dentists recommend is toothpaste last and not to rinse.

Either way, if you're doing all three then you're ahead of 90% of tooth owners

My hygienist is very against mouthwash because it kills the good germs. But yeah I also just learned that you floss first when I was always taught to floss last. Doesn't make sense to go last I should've figured that one out.

then let the toothpaste sit on your teeth for ten minutes instead of rinsing immediately.

So is that also after I throw up from the toothpaste on my teeth? When do I rinse my mouth after barfing?

If you're a psychopath. Who doesn't rinse?
