Is it safe to let a baby teethe on a silicone necklace mom wears?
Based on 1 peer-reviewed studybaby
Verdict: Use Caution
Short sessions yes, all-day no. Silicone releases more when warmed by skin.
What's actually in it
Silicone teething necklaces are platinum-grade silicone in good brands. Worn all day against mom's warm skin, they release slightly more siloxanes than a silicone item in a drawer.
What the research says
A 2025 study in J Hazard Mater showed siloxane release rises with temperature. Wear and chew adds up.
Short teething sessions are fine. Take the necklace off when baby isn't actively using it, and replace every 6 months.
