Toothbrushing

Toothbrushing is an interaction available in The Sims, The Sims 2: Apartment Life and The Sims 3. You can access it from the medicine cabinet. It affects the Hygiene need. In The Sims 3 it gives the moodlet "Minty Breath". Neat Sims occasionally get a wish to "brush teeth".

Trivia
In The Sims 3, the "brush teeth" wish always appears if a Sim eats an onion.
