Dentists needs more research/expertise to practice their profession: An honest advice

Five visits to different dentists in INTERCARE AND MEDICROSS in Cape Town, yet the same problem. They fix one problem and create another. This whole profession needs to be reviewed. Medical doctors diagnose and give you the right medication, and you get well. These dentists keep breaking your teeth one after the doctor and charge ridiculous fees. Maybe they need PhDs and more experts to do more research on their profession instead of licensing first-degree graduates who open their surgeries to the public. I am tired of unending visits for a small broken tooth problem that must be pulled out. Putting a crown on a cracked tooth does not help. Their association should do something as people are suffering from the pain caused. Don't allow them to open a practice if you don't have a postgraduate degree. Simple.
