Well, I have a lot of practicing to do before I feel comfortable with the air powder polishing!! I felt like I was all thumbs. I did pass off 2 pe's today so that was good. I'm going to have to practice at least once more before I try to pass off that air powder polishing pe. That was really just sad...:-( I felt bad for my patient. I kept suctioning her tongue, cheeks, lips everything except the powder! And the powder went EVERYWHERE!!! I don't see myself doing this very often unless there is a stain I think really needs it.
