a crown = a jar with worms
I and my family went for more than 2 years and spent thousands and thousands dollars there. Dr. Benk's answers to everything is a crown, because that generates the top dollars for him, which is ok if that fixes the problem. But the crowns were installed without careful treatment and diagnosis, often made things worse. I eventually had to redo every crown he installed, one of them turned to be root canal, two turned to be implant.
