Visited the dentist this week only as part of the treatment he told me I should brush my teeth before breakfast not after. I was taught as a child at both Brownies and primary school - apart from my parents - and nobody has ever said anything to me since. I have always gone to the dentist every 6 months. It was clearly the method used 40 years ago but AIBU to think someone should have said something if science decided there were better methods? IABU to expect to be told - I should keep on top of it myself, IANBU - health professionals should keep patients informed of new thinking in healthcare?
