Most patients who file a formal complaint against a dentist do so by way of the law concerning complaints. In 2017 the law concerning complaints was changed radically, with the intention of making the law easier for the patient to make use of and providing the patient with a financial settlement. This article considers the extent to which the possibility of being compensated has had the effect of encouraging patients to file claims in the case of the Royal Dutch Dental Association (KNMT), the complaints service with which most dentists are associated. The article also considers whether the new law has made the process of filing a complaint more readily accessible. Finally, if the law of complaints has become more appealing for patients to make use of, one could imagine that fewer cases would find their way to the disciplinary board. For that reason, the number of disciplinary complaints in 2017 is compared to the number for 2016.
