Dentist: Do as I Say, Not as I Do?

So I went to the dentist today (no cavities). And the dentist (or dental hygentist, I guess) was, as usual, berating me for not flossing enough. And then told me how important it is to floss before you brush. That way you can get all the bad stuff out from in between your teeth first, and use the toothbrush as the final step to get rid of it.

Made sense to me.

He then went on to do a complete cleaning - water pick, then regular pick, then polish, and then floss.

umm. Wait did I get that order right?

uhh...yeah, that was the order

Floss first, except when your a dentist?

I am so confused.
