The Problem Hiding Inside That Gel Ring
Walk into any baby gear store and you’ll find gel-filled or liquid-filled teething rings stacked near the checkout — colorful, cool-looking, and marketed as soothing. They’ve been around for decades, which is part of why parents still reach for them without a second thought. But the design that makes them appealing — a soft outer shell surrounding a reservoir of liquid or gel — is exactly what makes them a problem.
Pediatric guidance consistently advises parents to avoid teethers filled with liquid, because a baby’s chewing can easily break the ring, causing a foreign liquid to spill into the child’s mouth. That’s the basic mechanical risk. But the hazards don’t stop at a burst seam.
When it comes to filled teethers, a puncture doesn’t only cause a leak — it may also lead to bacteria or mold growth inside the ring itself, with the potential for serious stomach distress, or worse. Because the interior is sealed and wet, parents often can’t see contamination building up. A ring that looks fine on the outside may have already been compromised.
And freezing them — a common instinct when you want extra relief for swollen gums — makes things worse. A pediatric intensive care nurse warns: “Do not freeze liquid or gel-filled teething rings — they can crack. They will also become too hard and may injure your child’s gums.”
There’s also a chemistry concern that doesn’t get nearly enough attention. Research testing 59 teethers — including solid, gel-filled, and water-filled models — for 26 potential endocrine-disrupting chemicals found that gel and water-filled teethers contain preservatives such as parabens, which can affect the endocrine system. Endocrine disruptors are chemicals that can interfere with the body’s hormonal balance and could potentially lead to developmental, reproductive, neurological, and immune system issues. The fill composition in many gel teethers is not disclosed on the packaging, leaving parents with no way to assess what their baby is actually being exposed to when the outer shell gives way.
What Medicated Teething Gels Add to the Picture
Gel-filled teething toys are one category of concern. Topical teething gels — the kind rubbed directly onto gums — are another, and the regulatory record on those is stark.
The FDA has warned that lidocaine, used in some medicated teething products, can be harmful to infants. Reactions can include seizures, brain injury, heart problems, and death. The FDA reviewed 22 reports of serious reactions, including deaths, in infants and young children 5 months to 3.5 years of age given oral lidocaine for teething treatment. The American Academy of Pediatrics responded by recommending against putting any prescription or over-the-counter pain relievers containing lidocaine or benzocaine on babies’ gums.
In 2018, the FDA requested that companies stop marketing over-the-counter benzocaine-based teething remedies for use in infants and children. These products were sold as gels, sprays, ointments, solutions, and lozenges under brand names including Baby Orajel, Anbesol, and others.
Beyond the active ingredients, these products are not useful for teething pain because they wash out of the baby’s mouth within minutes. So even setting aside the safety concerns, they don’t reliably do what parents hope they’ll do.
Homeopathic teething tablets carry their own documented risks. The FDA recalled Hyland’s teething tablets after lab analysis found inconsistent and elevated levels of belladonna, a toxic substance, with reports of seizures in infants. The pattern across all of these product types is consistent: the teething aisle is not self-regulating, and “designed for teething” is not the same as “safe for teething.”
The 2026 Recall Wave: A Pattern Worth Knowing
If the chemical risks feel abstract, the 2026 CPSC recall record makes the structural risks concrete. Multiple pull-string teething toys were recalled this year for choking hazards — a reminder that design flaws in teethers can be just as dangerous as material flaws.
The U.S. Consumer Product Safety Commission issued a recall involving more than 100,000 children’s teething toys due to the risk of serious injury or death from choking, following a similar action earlier in the year involving an almost identical product sold by another company. The CPSC confirmed it was aware of 11 choking incidents from the recalled product.
That recall followed a similar February recall of AiTuiTui teething toys, which involved nearly 50,000 products and multiple choking incidents linked to unsafe silicone strings.
These weren’t fringe products — they were sold on major retail platforms, priced accessibly, and purchased by parents who reasonably assumed marketplace availability implied safety. Teething toys are one of the safest, most pediatrician-endorsed ways to soothe a teething baby when used correctly — but not every product on the market is safe, and several popular options come with explicit warnings from the AAP and FDA.
What Pediatricians and Pediatric Dentists Actually Recommend
Once you strip away the products with documented hazards, the guidance from pediatric professionals converges on a short list of safe materials and design principles.
Material comes first. Pediatric dentists consistently recommend teethers made from food-grade silicone or natural rubber, free of BPA, phthalates, PVC, parabens, and synthetic dyes. Food-grade silicone has a particular advantage: it is naturally free of harmful chemicals like BPA, phthalates, and PVC, eliminating the risk of chemical migration into a baby’s mouth. Silicone is also non-porous and highly heat-resistant, meaning it can be safely sterilized by boiling or steaming without degrading or growing mold.
One-piece construction matters more than most parents realize. Any teether that can separate into parts — including those with detachable handles, beads, or liquid-filled compartments — poses a choking or aspiration risk and should be avoided. This is why the one-piece solid silicone design is the benchmark that pediatric dentists keep returning to. Hygiene should also be built into the design: toys without deep crevices, hollow centers, or openings where residue can trap and grow mold are preferable, and the best options are dishwasher-safe or can be fully sanitized.
Chilled, not frozen. Most silicone and rubber teething rings can be safely refrigerated. A chilled (not frozen) toy can reduce inflammation and provide a welcome distraction — just be sure to wash them frequently with warm, soapy water to prevent bacteria or mold. Freezing a solid silicone teether is generally safer than freezing a gel-filled one, but even solid teethers can become too firm when frozen solid, risking gum bruising.
Simple non-toy options still work. Most pediatric dental professionals recommend non-medicated approaches for teething discomfort. Gentle gum massage with a clean finger, chilled (not frozen) teething rings, and additional comfort from caregivers are often sufficient — these methods avoid the risks associated with topical anesthetics while still helping reduce inflammation and discomfort.
For parents whose babies have started solids, a chilled silicone feeder with puree can serve double duty — soothing gums while introducing food textures. And when teething discomfort is severe, the AAP says it is acceptable to ask a pediatrician about a weight-appropriate dose of acetaminophen. Ibuprofen may be used in babies over 6 months with pediatrician guidance. Always confirm the appropriate dose for the child’s weight.
How to Choose a Teether You Can Actually Trust
The teether market in 2026 is large enough that “solid food-grade silicone” still needs to be verified, not assumed. A few practical filters:
Read the material claim specifically. The label should explicitly state 100% food-grade silicone — not just “silicone” — and should include BPA-free, phthalate-free, and PVC-free claims. Vague material descriptions are a signal to look elsewhere.
Check for independent lab testing. Any brand worth trusting will have its products tested by a third-party, government-accredited lab — not just self-certified. Look for explicit mention of CPSC compliance or equivalent safety standards.
Inspect regularly. Inspect every teether weekly and throw it out at the first sign of cracks, soft spots, peeling, mold, or any structural failure. A teether that was safe at purchase can degrade with heavy chewing over time.
Avoid anything with small attachments, strings, or a hollow interior. The 2026 recalls all involved teethers with strings or appendages that could detach and lodge in a baby’s airway. Solid, one-piece construction is the design principle that eliminates this category of risk.
Loulou Lollipop’s silicone teether collection is built around exactly these principles — 100% food-grade silicone, free of BPA, PVC, phthalates, lead, and cadmium, fully tested by an independent lab and meeting CPSIA standards. Their teether sets are designed as solid, one-piece forms with multi-textured surfaces — no gel fill, no detachable parts, no hidden interior where bacteria could grow. As the original designer of silicone donut teethers, ice cream cone teethers, and macaron teethers, the brand has built a catalog that’s both fun and safe.
Teething is genuinely uncomfortable for babies and exhausting for parents. The instinct to reach for whatever promises the fastest relief is understandable. But the safest path through this phase is also the simpler one: a solid, food-grade silicone teether from a brand that publishes its testing results, paired with a chilled cloth and a lot of patience.
