For children under the age of three, what is the recommended amount of toothpaste?

• A. A full pea-sized amount
• B. A smear or rice-sized amount
• C. A quarter-sized amount
• D. A half-teaspoon

Answer: (B)

For children under the age of three, the recommended amount of toothpaste is a smear or rice-sized amount. This is crucial because young children are still learning how to brush their teeth and may not have developed the ability to spit out excess toothpaste effectively. By using a very small amount, the risk of fluoride ingestion is minimized, which helps prevent dental fluorosis—a condition that can occur from swallowing too much fluoride during the early years when teeth are developing.

Using the correct amount of toothpaste also encourages the child to get accustomed to brushing without overwhelming them with too much foam or taste, making it a more positive experience in establishing good oral hygiene habits. It's important to ensure that while the quantity is small, the toothpaste is fluoride-containing, as this aids in preventing cavities and strengthening the enamel of the developing teeth.
