tbh, im not sure about scotland, as it may well be different to england. Was it an nhs dentist she saw? In England you would nly pay �198 maximum for any course of NHS treatment, no matter what that course of treatment or how much work was done. In England you can get an HC2 certificate if you are on a low income which entitles you to free treatment, but being a student wouldnt automatically qualify you - it would depend on how much money you had. In england, you cant apply for a refund retrospectively either
