sure is news to me. I keep seeing ads showing someone bleeding from the eyes (sorry!) and saying you would see a doctor if this happened so why don't you take action when bleeding from the gums. And your man thinks it's actually healthy?? Anyway, going to see a dentist is about avoidance of pain. Anyone who thinks it's his job to inflict it should be working at Abu Ghraib or somewhere. I'd think seriously about changing dentists if I were you.
I don't know about polishing fillings, that probably makes sense. But why should that stop him polishing enamel as well? I look forward to reading any replies from someone with more experience, but I'd be out the door myself.
