The aim was to examine how socioeconomic and cultural factors affect the risk of caries among children and adolescents with a foreign background in Western Europe. Method: A general literature study was conducted based on 18 peer-reviewed scientific articles published between 2015 and 2024. Articles were retrieved from the databases of CINAHL (DOSS) and Medline, using defined search terms and inclusion/exclusion criteria and were assessed to be of high quality. Results: Socioeconomic factors such as low parental education, income and unemployment were linked to an increased risk of caries. Other influential factors included the ages of the mother and child at migration as well as the parent`s country of origin in health literacy also contributed.  In addition, sociocultural aspects like negative attitudes toward dental care, language barriers, poor oral hygiene, and unhealthy lifestyle habits influenced care seeking behaviors and preventive practices. Conclusion: Children and adolescents with a foreign background in Western Europe are at greater risk of caries due to the combined effects of socioeconomic and sociocultural factors. Key risk factors include low parental education, income, and health literacy. More qualitative research is needed to deepen understanding and capture variation within migrant groups across Western Europe.
