The Label Says ‘BPA-Free.’ That Doesn’t Mean Much.
A lot of parents buy a plastic teether, see the words “BPA-free” on the packaging, and assume the job is done. The problem is that BPA-free does not mean chemical-free. Manufacturers sometimes replace BPA with structurally similar compounds — BPS or BPF — and the product still gets to wear that reassuring label. One study found that a majority of teethers labeled as “BPA-free” actually contained BPA anyway.
The broader issue with plastic teethers is the category of chemicals called phthalates — plasticizers added to make plastic soft and flexible. These are the chemicals that give a cheap plastic teether its squishiness, and they tend to leach out during normal use. Saliva, warmth, and the mechanical stress of chewing all accelerate that process. BPA and phthalates are believed to be endocrine disruptors, meaning they can interfere with hormone signaling — a particular concern in infants whose endocrine systems are still developing.
So when parents ask “how do I know if a baby teether is safe,” the honest first answer is: checking for a single “BPA-free” label is not enough. You need to look at the base material, the certifications behind it, and how the product was tested.
What Food-Grade Silicone Actually Is (and Why It’s Different)
Silicone is not a plastic. It’s a synthetic polymer built from silicon and oxygen — silicon being a natural element derived from sand — and its chemical structure is fundamentally different from the petroleum-based polymers that make up most plastics. That distinction matters for safety.
Food-grade silicone is a specific designation: to earn it, silicone must meet strict standards confirming it is safe for direct contact with food and, by extension, safe for mouthing. In the US, that means passing FDA food-contact standards. In Europe, the equivalent is LFGB certification. Both require testing to confirm the material won’t release harmful substances under normal use conditions.
The safety profile of food-grade silicone comes down to a few concrete properties. First, it is chemically inert — it doesn’t react with saliva or other substances, which means it doesn’t leach. Second, it is temperature-stable: high-quality food-grade silicone can withstand boiling water for sterilization and refrigerator temperatures for soothing without warping, cracking, or releasing compounds. Third, its surface is non-porous, which resists the growth of bacteria and mold between cleanings.
Food-grade silicone does not contain BPA, PVC, or phthalates. It doesn’t need them — it achieves its flexibility through its polymer structure, not chemical additives.
Side-by-Side: Silicone vs. Plastic Teethers
| Feature | Food-Grade Silicone | Plastic |
|---|---|---|
| Base material | Silicon + oxygen polymer (from sand) | Petroleum-based polymer |
| BPA | None | Often present; “BPA-free” versions may substitute BPS/BPF |
| Phthalates | None | Commonly used to add flexibility |
| Chemical leaching risk | Very low (chemically inert) | Higher, especially under heat and chewing stress |
| Sterilization | Boiling water, dishwasher-safe, fridge-safe | Many plastics warp under heat; limited sterilization options |
| Durability | Resists cracking, crumbling, and brittleness over time | Can crack or degrade with repeated use |
| Certifications to look for | FDA food-contact, LFGB, CPSC/CPSIA, BPA/phthalate/PVC/lead/cadmium-free | CPSC/CPSIA; “BPA-free” label alone is insufficient |
| Hypoallergenic | Yes | Not reliably |
| Ease of cleaning | Dishwasher-safe, boilable | Variable; heat may degrade material |
| Price | Slightly higher | Generally lower |
The table above covers the core tradeoffs. Plastic teethers tend to cost less upfront, but that advantage narrows when you factor in the need to replace them more frequently as they degrade. Silicone teethers, by contrast, hold up to the physical demands of teething — squeezing, dropping, gnawing — without breaking down structurally or chemically.
What Certifications to Actually Look For
Certifications are where the real due diligence happens. A few terms and standards worth knowing:
FDA food-contact standards (US): Confirms the material is safe for direct contact with food and mouths. This is the baseline for any food-grade silicone claim to be credible.
LFGB (Germany/EU): Often considered a stricter standard than FDA for food-contact materials. Products passing both FDA and LFGB testing are generally well-vetted.
CPSC and CPSIA (US Consumer Product Safety Commission / Consumer Product Safety Improvement Act): These are the US federal safety standards that cover baby products. Look for products that explicitly exceed CPSC and CPSIA requirements — not just meet them.
ASTM F963: The toy safety standard that covers mechanical hazards, small parts, and material quality. Teethers sold in the US should comply with this.
Beyond certifications, look for third-party testing — meaning an independent lab, not the manufacturer’s own facility, verified the claims. And be skeptical of vague language: terms like “natural,” “non-toxic,” and “hypoallergenic” are not legally defined by the FDA and carry no regulatory weight on their own.
One practical check: look for explicit statements that a product is free of BPA, PVC, phthalates, lead, and cadmium. Those five should all be named. A product that only mentions BPA-free is leaving gaps.
The Verdict for Parents
For parents trying to make a straightforward decision: food-grade silicone is the safer material choice for baby teethers, and the evidence behind that conclusion is consistent across pediatric guidance, independent testing, and material science.
Plastic teethers are not automatically dangerous — a well-certified, third-party-tested plastic teether that genuinely meets CPSC/CPSIA standards is better than an uncertified silicone product. But in practice, the plastic category carries more variability and more chemical risk than food-grade silicone does. The leaching concern is real, the “BPA-free” label problem is documented, and the sterilization limitations are a practical inconvenience on top of the safety concerns.
Food-grade silicone’s advantages stack up across every dimension that matters for a teether: chemical safety, durability, ease of sterilization, and hypoallergenic properties. The slightly higher price point reflects those material qualities.
When shopping, the checklist is short: 100% food-grade silicone (explicitly stated), BPA/PVC/phthalate/lead/cadmium-free, third-party tested, and CPSC/CPSIA compliant. One-piece construction eliminates seams where bacteria can collect and reduces choking risk from detachable parts.
Loulou Lollipop’s silicone teethers are made from 100% food-grade silicone meeting FDA standards, free of BPA, PVC, phthalates, lead, and cadmium, and independently tested before each production run — exceeding US CPSC and CPSIA safety requirements. The inks used in the designs are water-based and food-safe, injected into the silicone rather than applied on the surface. For parents who want to skip the certification research and buy with confidence, that combination of material and testing documentation covers the checklist above.
If you’re also looking at teething sets or clip-style teethers that stay attached to a stroller or carrier, the same material standards apply — check the teething sets collection for options that pair a textured teether with a secure clip, all in food-grade silicone.
