For the last few years, every time DS12 goes to the dentist, his father (who takes him) asks about the tartar: what we can do about it and will he remove it. Every time the dentist says its fine (NHS). It's not going to come off on its own, and I am really quite concerned about it now - hopefully that picture shows it clearly enough.
Does anyone know whether private dentists or hygienists will remove it from an almost 13 year old, and also have any idea why the dentist he usually sees won't - whether it's because of his age, or because he's NHS, or something else? Because everything I read talks about the potential problems tartar will bring.
