Do baby pacifiers release bisphenol A into spit?
Yes. Recent peer-reviewed research confirms that bisphenol A (BPA) migrates from commercially available pacifiers into the mouths of infants and toddlers.
What's actually in it
Pacifiers are often made from plastics that can contain bisphenol A (BPA). This chemical is a known endocrine disruptor, meaning it can interfere with your baby's natural hormones. When a baby uses a pacifier, the constant contact with saliva and the mechanical action of sucking can cause these chemicals to leach out of the material and directly into their mouth.
What the research says
A 2026 study in Environ Sci Pollut Res Int specifically looked at the migration of BPA from pacifiers sold on the market. The researchers used advanced testing methods to measure how much of the chemical moved from the pacifier into a liquid that mimics human saliva.
The study confirmed that BPA does indeed migrate from these products. This means that every time your baby uses a pacifier, they are likely being exposed to this harmful chemical. This peer-reviewed research highlights the reality that even products designed for infants can be a source of chemical exposure.
