depends whether your dentist is private or nhs, mine is private when i first went when i was expecting he oput me through as nhs and i got it free, but when i went last week, i had to pay as he was no longer allowed to pick and choose nhs patients - other wise if i wanted it free i had to see another dentist. i trust this guy and dont want to change, so i paid. i'm not very trusting with dentists due to past experiences
