I wouldn't. I think I'd rather have a nice hygienist, with a good chair side manner, do it than an emotionally detached dentist. They do the prep work for it. If they've seen it done dozens of times up close, they could do it.
Why are we talking about dentists? This came up because I made an analogy about my previous job. And Carolla quipped about it, as a distraction from what I was actually talking about. She just had to stop the discussion to put me in my place, I guess. Whenever you see an opportunity to invalidate me, my experience, and put me in my place - this crowd will do that. There are a particular few that you've learned that from over the years.
We all know there are work environments where the superiors do much less and get paid more. They might have more formal (as opposed to experiential) education but in lots of cases, if they've been in a cushy job awhile, or get off on power, it's outdated and they just use it as a status marker. Nobody remembers everything they learned in academia that they learned several years ago. They preserve and expand their knowledge with experience. Hygienists are capable of the same.
