Just had my first visit in 4 years to the dentist. I need a filling at the back of one of my top side teeth (either 2nd or 3rd along from front left tooth) I can get an amalgam filling for free or pay £55 for a white one. Has anyone else had to get a filling here? Can you see the metal ones or is it concealed enough? Dentist didn't seem bothered, said it was entirely up to me. Hate that they can't include the white ones in the free treatment
