I have seen two NHS dentists and two private ones who both say I need different amounts of filling.
The two private ones have said that I need 4 fillings which are on molar teeth.
One of the NHS dentists identified one hole and the other, two.

I am wanting to see a private dentist so that I can put a cosmetic filling in, my NHS dentist has said that he has put a white filling in, but it doesn't look very white and there a lot of filling hasn't been used to restore it to the original shape (its a large cavity).
I am worried that if I go to a private dentist again, they will just say that I need these 4 fillings again (for what looks like an extremely small hole).

Who do I trust, NHS or Private?
