The Short Answer — and Why It’s More Complicated Than a Label
Most silicone baby teethers sold in the United States are safe. But “safe” is not a single stamp or a marketing claim — it’s the result of several overlapping federal regulations, each targeting a different hazard. When parents search for a teether and see phrases like “BPA-free,” “food-grade silicone,” or “CPSIA certified,” those words refer to distinct legal requirements that apply at different points in the supply chain. Understanding what each standard actually covers helps you evaluate a product more precisely than any packaging claim can.
Silicone itself has a strong track record. Food-grade silicone is an FDA-approved synthetic rubber made of bonded silicon — a natural element found in sand and rock — and oxygen, with a long track record of safe use in baby bottle nipples, pacifiers, and teethers. But the material’s inherent safety is only part of the picture. The product still has to meet structural, chemical, and size requirements set by US federal law before it can legally be sold.
The Regulatory Framework: Four Overlapping Rules
Silicone baby teethers sold in the US are governed primarily by the Consumer Product Safety Commission (CPSC) through a combination of rules under the Consumer Product Safety Improvement Act of 2008 (CPSIA) and the mandatory toy safety standard, ASTM F963.
ASTM F963-23 — The Toy Safety Standard
Section 106 of the Consumer Product Safety Improvement Act of 2008 (CPSIA) made ASTM F963 a mandatory consumer product safety standard for children’s toys. For ASTM F963-23, the effective date is April 20, 2024. This standard covers a wide range of hazards — material quality, flammability, small parts, heavy metals, and more — and not every section applies to every product. Certain teethers and teething toys must comply with 16 CFR Part 1510, and toys with domed ends must meet additional performance requirements.
For teethers specifically, the small-parts provisions matter a great deal. 16 CFR Part 1501 prohibits the sale of toys and products containing small parts that are meant for children under 3 years of age because these products can cause choking, breathing, or ingestion hazards. A teether that breaks apart under normal chewing pressure and produces a piece small enough to lodge in an infant’s throat is a banned hazardous substance under that rule — regardless of the material it’s made from.
The Phthalate Ban — 16 CFR Part 1307
This is arguably the most consequential rule for parents evaluating chemical safety. A “child care article” is defined as a consumer product designed or intended by the manufacturer to facilitate sleep or the feeding of children age 3 and younger, or to help such children with sucking or teething. Teethers fall squarely into that definition. Examples of child care articles include children’s sleepwear, infant and toddler bottles, sippy cups, utensils, bibs, pacifiers, and teethers covered by the prohibition on phthalates.
Section 108 of the Consumer Product Safety Improvement Act, codified at 15 U.S.C. § 2057c and 16 CFR Part 1307, prohibits the manufacture for sale, offer for sale, distribution in commerce, or importation into the United States of children’s toys and child care articles that contain more than 0.1% (1000 ppm) of specified phthalates in an accessible plasticized component. The banned list includes DEHP, DBP, BBP, DINP, DIBP, DPENP, DHEXP, and DCHP. This rule exists because for infants, exposure to DINP was primarily from diet, but exposure was also due to DINP in teethers and toys.
Food-grade silicone avoids this issue by design. Food-grade silicone is a non-toxic silicone elastomer — a polymer built on a silicon-oxygen backbone — specifically formulated for safe contact with food, made without harmful additives such as BPA or phthalates. Because silicone is not a PVC-based plastic, it does not require phthalate plasticizers in the first place. That said, the law still requires third-party testing and a Children’s Product Certificate (CPC) to confirm compliance.
Lead Content — 16 CFR Part 1303
All accessible substrate materials in children’s products must comply with the federal lead content limit. The total lead content in any accessible part of a rattle must not exceed 100 ppm (0.01%). The same limit applies to teethers. Silicone is not a lead-bearing material, but surface colorants and inks applied to a teether can be, which is why reputable manufacturers use water-based, food-safe inks rather than surface-applied paints.
Third-Party Testing and the CPC
Self-certification is not enough. Third-party testing and certification are required for toys designed or intended primarily for children 12 and under. Once you have identified the applicable requirements for your product, you must use a CPSC-accepted, third-party laboratory to perform testing to show that the product complies with the toy standard. The resulting Children’s Product Certificate documents each regulation the product was tested against and must be available to retailers and consumers on request.
What “Food-Grade Silicone” Actually Means
Food-grade silicone must meet stringent safety standards — FDA in the US, LFGB in Germany and the EU — to ensure it releases no toxins into food. The FDA designation confirms the material has passed migration testing, meaning it does not leach harmful compounds under normal use conditions, including repeated washing and temperature changes.
Some manufacturers go further and source LFGB-certified silicone, which is considered the gold standard for food safety in Europe, tested more thoroughly than FDA-grade silicone to ensure that no dangerous chemicals are released into food when products are used. When a teether is described as made from “100% food-grade silicone,” that phrase should mean the material has been tested to one of these standards — not simply that the manufacturer chose to use the term.
A quick practical check: quality food-grade silicone should have no noticeable odor, should not turn white or chalky when flexed (a sign of cheap fillers), and should not leave any taste on your fingers. The silicone should have no odor, not change color or turn white when flexed — signs of fillers — and it should not impart any taste or smell to food.
And because silicone is not plastic, it sidesteps the BPA concern entirely. Regulatory bans such as the US FDA’s 2012 prohibition on BPA in baby bottles and sippy cups pushed manufacturers toward safer materials like silicone. Some BPA-free plastics use substitutes like bisphenol S (BPS) or bisphenol F (BPF), which may have similar health risks — silicone avoids these concerns entirely.
Red Flags to Watch for When Buying Online
The US market for baby teethers includes products from dozens of countries at wildly different price points. Some arrive without a CPC, without third-party test reports, or with vague material descriptions that don’t specify silicone grade. A few things worth checking before purchasing:
- No mention of CPSIA compliance or third-party testing. Compliant products should reference CPSC or CPSIA standards and confirm independent lab testing. Absence of this information is worth noting.
- Unusually low price combined with strong chemical odor. Cheap fillers are sometimes blended into silicone to reduce material costs. Food-grade silicone is the safest option when it comes to non-toxic teethers — it’s not plastic, but has beneficial properties like being flexible and water-resistant, while being free of BPAs and phthalates. A strong smell suggests the product may not meet food-grade standards.
- Teething jewelry (necklaces or bracelets). The US Food and Drug Administration warns against using teething necklaces or bracelets made of amber, silicone, marble, or wood. Canadian Paediatric Society research found these pose strangulation and choking hazards, with case reports of children dying from these products. This warning applies regardless of material.
- No age guidance or choking hazard labeling. US law requires appropriate warning labels on products for children under 3. A teether with no such information has likely not gone through proper compliance review.
For parents buying in the US, looking for brands that publish their CPC documentation or explicitly state that products are tested at CPSC-accepted third-party laboratories is the most reliable filter available.
How Loulou Lollipop Approaches Teether Safety
Loulou Lollipop’s silicone teethers are made from 100% food-grade silicone meeting FDA standards, and are free of BPA, PVC, phthalates, lead, and cadmium. They exceed all US CPSC and CPSIA safety requirements. Products are fully tested by an independent lab and meet CPSIA standards.
The brand also addresses a detail that often goes unnoticed: the inks used for color. The teethers are made from natural silicone found in sand using a manufacturing process that meets high environmental standards, free from harmful chemicals and featuring 100% water-based and food-safe inks that are injected into the silicone instead of applied on top. That distinction matters because surface-applied colorants can chip or flake off — injected pigments cannot.
For parents who want a broader selection, the full teething collection includes single teethers, teething rings, teething mitts, and sets — all built to the same material and compliance standards. Loulou Lollipop is also a certified B Corp, which means its supply chain and environmental practices are independently audited, adding a layer of accountability beyond product safety alone.
The Bottom Line on Safety Standards
Silicone baby teethers, when made from genuine food-grade silicone and manufactured to US federal standards, are among the safest teething options available. The regulatory framework — ASTM F963-23, 16 CFR Part 1307 on phthalates, 16 CFR Part 1501 on small parts, and the lead content rules — creates a meaningful baseline that reputable brands are required to meet and document through independent testing.
The gap between a compliant product and a non-compliant one is not always visible. It shows up in test reports, in material specifications, in how colorants are applied, and in whether a Children’s Product Certificate actually exists. When shopping for a silicone baby teether online in the USA in 2026, the most useful question to ask is not “is silicone safe?” — it generally is — but rather: has this specific product been tested against US federal requirements by an accredited third-party lab, and can the brand show documentation to prove it?
