For patients with considerable malfunctions, or where these could potentially develop, statutory health insurers completely cover the cost of correcting malpositionings of the teeth and jaws through orthodontic treatment in Germany. Based on the self-reported information from the second wave of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS Wave 2, 2014-2017), the uptake of orthodontic treatment was analysed. A total of 25.8% of the girls and 21.1% of the boys aged 3 to 17 years are receiving regular orthodontic treatment. Uptake of treatment is very much dependent on age. The highest rates are found among 13-year-old girls (55.0%) and 14-year-old boys (50.8%). Compared to the data from previous KiGGS waves, the trend over approximately ten years has seen a significant increase of orthodontic treatment across all age groups. More health services research and a broader discourse on current treatment practices and their benefits are desirable.
