Hi I recently went to the dentist with back pain on my upper back molar dentist said it was cracked and would need a deep filling and charged me band 2 pricing which is fine he said if pain does not go away that I was looking at either tooth extraction or a root canal on molar but the root canal will cost me £1000 I did not think nhs dentists could charge me over band 3 as thought root canals was covered under band 2 does anyone have any advice as I am still in pain and having to take painkillers all day every day over using them
