Fluoride ingestion from toothpaste: fluoride recovered from the toothbrush, the expectorate and the after‐brush rinses

Abstract

Fluoride ingestion from toothpaste is significantly reduced by rinsing and/or spitting during toothbrushing. Recommendations that younger children use small amounts of toothpaste (< 0.5 g) and that children using toothpaste with > or = 1000 ppm F rinse their mouths after brushing continue to be valid.
