⚠️
USE WITH CAUTION
Danger Score: 5 (Lower is safer)
Quick Answer: Sodium Fluoride use with caution for 5+ year old children when used in topical products. Kids may have different tolerance levels.

ℹ️General Overview

For school-age children (5 years and older): moderate concern. Sodium fluoride can irritate skin and eyes and is restricted for use in cosmetic skin products in some countries. It is used safely in dental products when used exactly as directed, but should not be applied to the skin as a general cosmetic.

✅What to Do

If your child is 5 or older, only use fluoride when it is in a dental product made for children and follow the product directions. Supervise tooth brushing so your child spits out toothpaste and does not swallow it. Do not use products that list sodium fluoride as a skin ingredient for everyday skin care. Avoid getting it in the eyes and do not apply to cuts or broken skin.

⚠️Warnings

Do not use sodium fluoride in skin care products for children because Health Canada and the EU place restrictions on cosmetic use, and EU hazard labels mark it as a skin and eye irritant. The U.S. food agency also prohibits use in food. Watch for redness, burning, stinging, or eye pain after contact. If your child swallows a mouthful of fluoride toothpaste or shows nausea, vomiting, drooling, or tummy pain, call poison control or your doctor right away. Also be aware that fluoride from water, toothpaste, supplements, and dental treatments can add up — ask your pediatrician about total fluoride exposure.

Safety Risk Labels

This ingredient has the following documented risks:

Irritant: This ingredient is listed as an eye and skin irritant under EU hazard rules. That means it can cause redness, stinging, or sore eyes and skin on contact, so it is a real irritation risk if a child gets it on their skin or in their eyes (EU GHS classification).
Banned: Health Canada and the EU put limits or bans on its use in cosmetics, and U.S. food rules bar it from food uses. These government restrictions mean many regulators consider its use restricted or not allowed in some products.
Organ Risk: EU hazard labeling lists this chemical as toxic or harmful to non-reproductive organs with repeated exposure. While one Canadian source views the risk as low, the EU classification indicates a possible risk to organs like liver or kidneys if exposure is high or repeated.
Absorbed: It is used in different places, including limited food or additive uses noted by U.S. regulators, meaning people can get exposed in more than one way. Multiple exposure sources raise the chance the chemical can enter the body and add up over time.
