Correct answer: A — A small green pea (approximately 5 mm)

Health Canada and the CDA recommend that children aged 3-6 years use a pea-sized amount (approximately 5 mm) of fluoridated toothpaste (1000-1500 ppm fluoride). Children under 3 years should use a smear or grain-of-rice-sized amount. An adult should supervise brushing and encourage spitting (not rinsing) to maximise fluoride contact. These recommendations balance caries prevention benefit against the risk of dental fluorosis from ingestion.
