Socio-economic differences in health and health behavior are well-known. Our hypothesis was that toothbrushing frequency in adolescents predicts their education level in adulthood. The aim was also to study the role of toothbrushing in adolescents health-related lifestyle. Data from nationally representative samples of 12- to 16-year-olds (N = 11,149) were linked with register data on the highest level of education attained at age 2733 years. Adolescents with a low toothbrushing frequency reached only the lowest education levels. School achievement or sociodemographic background only partly accounted for the association. Exploratory factor analysis found four dimensions of health behaviors. At age 12, a low toothbrushing frequency was loaded highly with "street-oriented" behaviors, concentrated around smoking and alcohol use. At ages 14 and 16, it was associated with a "traditional" lifestyle of the less-well-educated. Altogether, a low toothbrushing frequency indicated selection into the less-well-educated stratum of society. This is likely to be reflected in socio-economic health differences in adulthood.
