Toothbrushing is an interaction available in The Sims, The Sims 2: Apartment Life and The Sims 3. It can be accessed from the medicine cabinet in The Sims and The Sims 2: Apartment Life, and from any basin in The Sims 3. It affects the Hygiene need. In The Sims 3 it gives the moodlet "Minty Breath." Neat Sims occasionally get a wish to "brush teeth," while Neurotic Sims often wish to brush their teeth multiple times.[TS3] Sims may autonomously brush their teeth if their hygiene is low.
- In The Sims 3 , the "brush teeth" wish always appears if a Sim eats an onion, or garlic.
