For toddlers and preschoolers (ages 2–5), sodium fluoride used on the skin can cause irritation and may be risky if swallowed. Regulators limit its use in some cosmetics, so it’s not a great choice for everyday skin products for young kids.
Avoid products that list sodium fluoride on the label for children’s lotions, wipes, or creams when possible. If you must use a product that contains it, keep it out of reach, do not apply to broken or irritated skin, avoid the face and mouth area, and supervise your child so they don’t lick or eat the product. Rinse eyes and skin with water if contact causes irritation. If you suspect your child swallowed a product containing sodium fluoride, call your local poison control center or seek medical help right away.
Regulatory agencies have restricted or limited use of sodium fluoride in cosmetics (see Health Canada and EU cosmetic rules) and classify it as a skin and eye irritant (EU GHS). It is also not allowed for use in food (U.S. FDA). These are the main sources of concern: irritation and use restrictions — not cancer or reproductive harm, which are low-level concerns according to the safety information available.
