Anyone had ‘airflow stain removal’ from hygienist?

[Hirik]

Did it work?

I had it - couldn't see any difference at all. I thought it was a con tbh.

H rates it. He said he'd never go back to normal hygienist. The airflow isn't painful and doesn't leave his teeth on edge. He actually asked fo a Groupon foe christmas.

haven't had it done but more info here @Hirik
