I have always looked after my teeth but still seem to need fillings. I have just had another talking to by my dentist about not snacking etc but I honestly don't have much sugar in snacks or drinks. I don't take any medication and follow a strict healthy diet to combat fatigue. Does anyone know if MS can be a causing factor? Maybe lack of vitamins or poor immune system? Also is there any financial help for massive dentist bills? I am able bodied and work so don't qualify for free NHS but just wondered if I was missing anything and if anyone could advise.
