What is the fluoride toothpaste guidance for children who cannot spit yet?

• A. Use a smear-sized amount (rice grain) on the toothbrush and supervise until they can spit.
• B. Use a pea-sized amount.
• C. Use a large amount.
• D. Use toothpaste without fluoride.

Answer: (A)

The main idea is balancing caries prevention with minimizing fluoride ingestion in young children who can’t spit yet. Using a smear-sized amount of fluoride toothpaste—the size of a grain of rice—on the brush provides fluoride’s protective effect against tooth decay while greatly limiting how much fluoride is swallowed. Close supervision helps ensure the child spits out toothpaste after brushing, reducing fluorosis risk while still gaining the benefits of brushing twice daily. A pea-sized amount is safer later, once the child can reliably spit. A larger amount increases ingestion risk, and toothpaste without fluoride loses the added protection against cavities.
