Crest and Colgate sued over fluoride in kids’ toothpaste, mouth rinse

Fluoride helps prevent cavities when applied topically to the teeth, but when ingested can pose significant risks, even kill young children, per new lawsuits.

Procter & Gamble and Colgate-Palmolive are among the defendants in six new lawsuits targeting the sale of toothpaste and mouth rinse for young children because the products contain fluoride, which can be harmful if swallowed in large quantities.
