Subpopulation: had extraction for wisdom teeth = yes.

^*Model: self-rated dental health = (Intercept) + gender + had a tertiary qualification + dentally insured + received multiple third molar extractions + age (years) + household income.

^†Set to zero because this parameter is redundant (reference category).
