How to Choose a Safe Teether for Your Baby

TL;DR: A genuinely safe teether should be EN 71 certified, the legally required toy safety standard in the UK and EU, and free from BPA, phthalates and other restricted chemicals. Choose a teether sized so it can't fit entirely in your baby's mouth or become a choking hazard if it breaks, and be cautious with liquid or gel filled designs, which have been recalled in the past over bacterial contamination risk. Silicone is the most common and easiest to clean material, while wood and natural rubber are solid alternatives as long as they still carry the same safety certification.

Teethers look simple, but not every one on the market is built to the same standard. Here's exactly what to check before choosing a safe teether for your baby.

What Makes a Teether Genuinely Safe?

A safe teether comes down to three things: certified materials, a size and shape that can't become a choking hazard, and a design that's genuinely easy to keep clean. A teether that looks soft and harmless can still fail on any one of these, so it's worth checking rather than assuming.

Check for EN 71 Compliance

Every teether sold in the UK and EU should comply with EN 71, the legally required toy safety standard. A teether counts as a toy under this regulation, specifically because it's designed to go in a baby's mouth, which triggers stricter testing than many other children's products. EN 71 covers mechanical safety (EN 71-1), flammability (EN 71-2), and chemical migration (EN 71-3), along with newer, more specific parts covering substances like BPA. Look for the CE or UKCA mark on packaging, and ideally the British Toy and Hobby Association's Lion Mark, which signals the manufacturer meets the legal requirements and a stricter trade code of practice on top.

Look for BPA-Free, Phthalate-Free Materials

Since a teether spends so much time in direct contact with a baby's mouth, material safety matters more here than with most other toys. Look specifically for a teether labelled BPA-free and phthalate-free, and ideally one that's been tested under EN 71-19, the specific standard covering BPA migration from toy materials. UK and EU REACH regulations also restrict substances like cadmium and certain dyes, so a genuinely safe teether should comply with both sets of rules, not just one.

Size and Shape Matter for Choking Safety

A safe teether needs to be large enough that it can't fit entirely into a baby's mouth, with no small, detachable parts that could come loose and become a choking hazard. Check for rounded edges rather than sharp corners, and avoid any teether with small decorative pieces, beads, or attachments that could separate from the main body with repeated chewing.

Silicone vs Wood vs Rubber vs Liquid Filled

Silicone is the most common teether material, and for good reason: it's soft enough to be gentle on sore gums, easy to clean, and simple to manufacture without unnecessary additives. Wood and natural rubber teethers are a solid alternative, often chosen for being a more natural material, as long as they still carry the same EN 71 certification as any silicone option. Liquid or gel filled teethers, often marketed for their cooling effect in the fridge, deserve extra caution, since this design has been linked to recalls in the past due to bacterial contamination once the seal is compromised. A solid silicone, wood, or rubber teether avoids that risk entirely.

Age Guidance and When to Introduce a Teether

Most teethers are suitable from around 3 months, though always check the specific age guidance on the packaging rather than assuming one size fits every baby. Introducing a teether too early, before a baby has good head and hand control, offers little benefit and adds risk without the coordination needed to use it safely.

How to Clean and Maintain a Teether Safely

A safe teether also needs to stay safe after repeated use, not just when it's new. Check the manufacturer's cleaning instructions, since some silicone teethers are dishwasher or steriliser safe while others need hand washing only. Inspect it regularly for tears, cracks, or discolouration, particularly around any seams, and replace it as soon as you spot damage rather than waiting for it to get worse.

Final Thoughts

Choosing a safe teether comes down to checking the certification rather than judging by how soft or colourful it looks on the shelf. Look for EN 71 compliance, BPA and phthalate-free materials, a choke-safe size and shape, and be cautious with liquid filled designs specifically. A little label-checking before you buy makes a genuine difference to how safe a teether actually is in daily use.

Frequently Asked Questions

What safety standard should a teether meet? 

Look for EN 71 compliance, the legally required UK and EU toy safety standard, along with a CE or UKCA mark on the packaging.

Is silicone safer than wood or rubber for a teether? 

Not necessarily. Any of these materials can be safe as long as the specific teether carries proper EN 71 certification and is free from BPA and phthalates.

Are liquid filled teethers safe? 

They carry more risk than solid designs, since liquid and gel filled teethers have been linked to bacterial contamination recalls if the seal is damaged. A solid teether avoids this risk entirely.

What age can a baby start using a teether? 

Most teethers are suitable from around 3 months, though always check the specific product's age guidance, since this can vary by design and size.

How do I know if a teether has become unsafe to use? 

Check it regularly for tears, cracks, or discolouration, particularly around any seams, and replace it immediately if you spot any damage rather than continuing to use it.
