Fair enough.

I can find articles about how they may be overused and less useful than thought… but you can find those sorts of articles for any medical treatment and frankly I’m not qualified to evaluate the evidence anyway.

I guess I was wondering if it was one of those things that was done in the 80s but now everyone thinks it’s a bad idea. Guess not!

Maybe they have become in-fashion again. Back then when I had the problems with bad sealed teeth, the dentist told me you don't do these anymore. But that was 20 years ago.
