Toothbrushing

Toothbrushing is an interaction available in The Sims, The Sims 2: Apartment Life, The Sims 3 and The Sims 4. It can be accessed from the medicine cabinet in The Sims and The Sims 2: Apartment Life, and from any basin/sink in The Sims 3 and The Sims 4.

Brushing teeth will provide a slight boost in hygiene. In The Sims 3, doing so also gives the "Minty Breath" moodlet, and in The Sims 4 it grants a confident +1 moodlet for 4 hours. Neat Sims occasionally get a wish to brush teeth, while neurotic Sims often wish to brush their teeth multiple times. Sims may autonomously brush their teeth if their hygiene is low.

Trivia

 * In The Sims 3, the "Brush Teeth" wish always appears if a Sim eats an onion or garlic.
