Does anyone know if it's usual for private dentists to charge pregnant women for dental checkups / treatment. My sister in law is 31 wks and was told that she has to pay as treatment is only free if you have an NHS dentist. I was under the impression that all pregnant women are entitled to free treatment. I also have a private dentist and when I was expecting I just had to sign a form to say I was exempt from charges. Anyone in the know about this?
