Cultural Tip
In German‑speaking households, asking about personal hygiene is common among family members and close friends, but it can feel intrusive in a formal setting. The reflexive construction ‘sich die Zähne putzen’ is standard; you’ll also hear the shorter ‘Zähne putzen’ without the reflexive pronoun, especially in headlines or instructions.
