Warning after study finds teething rings contain hormone-disrupting chemicals.

Endocrine-disrupting chemicals are banned from use in products for children.

However, no studies have ever tested plastic teethers for the presence of toxins commonly found in plastic that have been linked to increased risk of cancer, heart disease and obesity.

Now a study by the American Chemical Society warns that 100 percent of products tested contained Bisphenol A (BPA), Bisphenol S (BPS) or Bisephenol F (BPF) – so-called endocrine-disrupting chemicals, reports Daily Mail.

Most also contained parabens, and antimicrobials such as triclosan and triclocarban.

The researchers tested 59 solid, gel-filled or water-filled teethers purchased online in the U.S. for 26 potential endocrine-disrupting chemicals.

Although most of the products were labelled BPA-free or non-toxic, all of them contained BPA.

So-called endocrine-disrupting chemicals (EDCs) are found in thousands of everyday products, ranging from plastic and metal food containers, to detergents, flame retardants, toys and cosmetics.

This term covers a number of chemicals. One is called PBDEs, which are commonly found in flame retardants.

Bisphenol A in polycarbonate plastic is used for hard reusable bottles and food containers. Phthalates are used for disposable water bottles.

The invisible chemical cause neurological and behavioural disorders like autism and ADHD. They can also affect IQ.

It is also believed they manipulate hormones in a way that can cause cancer, diabetes, male infertility, and endometriosis.

The FDA is in the middle of an investigation into bisphenol A (or, BPA) – found in many American plastic water bottles – to assess how to regulate it.

The study also showed that the compounds leached out of the products’ surfaces into water.

Based on estimates of average use time and the body weight of a 12-month-old baby, calculations suggest that exposure to BPA and other regulated EDCs in teethers would be lower than the European standards for temporary tolerable daily intake levels.

However, these thresholds are set for individual compounds. Current regulations do not account for the accumulation of multiple EDCs, note the researchers.

Additionally, not all chemicals measured in the study are regulated.

The researchers say the findings could be used to develop appropriate policies to protect infants from exposure to potentially toxic chemicals found in teethers.

  • I would like to know how they come up with the link between obesity and toxins in plastic!


  • Maybe the old fashioned ways might be best. A hard solid rusk used to be used for teething when my children were young and it seemed to work.


  • I guess every product we use is questionable . It is up to our discretion to make the final judgement. I remember when considering dummy or no dummy, it may sound mean but no dummy, I knew that looking at how they are all made they could be a potential choking hazard, or a chemical may release from them ( there is always a batch of everything in any product that goes wrong). Then my little one started teething at 4 mths old, not old enough to understand how hard to bite or his own personal limitations, so sterile water over the hand towel in the freezer it is a cheaper and safer option and I had more control over it then a chemical releasing teether!


  • 33 years ago we had solid soft plastic teething rings – no gel or “water” in them.
    They have been used by a few babies, no punctures, very few marks of any type and easy to sterilize by pouring boiling water over it.


  • Thats crazy. How can something be sold as BPA free but not be? Surely there HAS to be stircter testing on products for dangerous chemicals. Especially for babies!!

    • I so agree. There needs to be stricter testing and policing, especially for items for babies and children .


  • It looks so important to check for these chemicals! Teething rings are so widely used.
