Q. Hi, I wonder if you can help answer my question. I have Sjogren’s syndrome (now being successfully treated) which has caused extensive enamel erosion and badly damaged many of my teeth.My dentist has recommended crowning approximately 7 teeth,including both incisors and molars.I am exempt from nhs charges due to disability, however he tells me that I will have to pay approx £300 per tooth crowned unless I am willing to have metal(gold) crowns.I want to clarify the nhs position on repairing severely damaged teeth re porcelain/white crowns – your own site and other DOH information seems to suggest that these are available in this kind of situation? Also to clarify, if not, is it possible for me as a patient to “top up” the cost of providing the metal crowns(i believe £198) which the nhs would cover, to allow me to have the porcelain/white ones? many thanks
