Every foreign dentist who wants to work in the Netherlands needs to be registered in the so-called BIG register. This is the register for healthcare professionals in the Netherlands.
The BIG requires a number of documents for your application. If you’re a foreign dentist from another European country, one of these documents is proof of language proficiency. You can obtain this proof by passing the Dutch language exam.
The level of the Dutch language exam is a B2+ level. Therefore, the minimum required level to work in the Netherlands is B2+.
