Is it necessary to become a specialist to do more complex treatments at the clinic?

To be able to perform orthodontics or implantology, a professional qualification is required, preferably from the Netherlands or a country recognized by the official institutes. To perform any other complex treatments, such as endodontics, prosthodontics, surgery, etc. you don’t need to be a specialist, but the dentist must have the knowledge and skills to be able to perform them.
