Food-Grade Silicone vs. Plastic Teething Toys: Which Is Safer for Babies?

The Label Problem No One Talks About

Walk into any baby store in 2026 and you’ll find shelves packed with teething toys claiming to be “non-toxic” and “BPA-free.” Those labels sound reassuring — until you learn that teething toys occupy a regulatory gap that baby bottles do not. In 2012, the FDA banned BPA from baby bottles and children’s drinking cups, but teethers were not included in that ban. That left manufacturers free to voluntarily claim BPA removal without any mandate to verify it. A 2013 study published in the National Library of Medicine found that a high percentage of teethers labeled as “non-toxic” or “BPA-free” still contained those exact chemicals.

So the material your baby gnaws on for hours every day deserves more scrutiny than a front-of-package claim. The two most common categories — food-grade silicone and plastic — behave very differently when it comes to chemical safety, durability, and how easy they are to actually clean.

Chemical Safety: Where the Real Difference Lives

Plastic is not a single material. It’s a category that includes polycarbonate, PVC, ABS, and other formulations, each with its own chemical profile. The two biggest concerns for parents are BPA (bisphenol A) and phthalates.

BPA is used to harden clear, rigid plastics and has been identified as an endocrine disruptor — a chemical that can interfere with hormonal signaling. An NIH-funded study found that BPA exposure can impact brain development and behavior in infants and young children. Phthalates are added to make plastics soft and flexible, and they are linked to hormonal imbalances and developmental issues. Research on infant exposure found that in most (81%) infants tested, seven or more phthalate metabolites were detectable in urine. While phthalates have been banned from toys sold in the US since 2018, older products and some imports may still carry them — and even “BPA-free” plastics sometimes substitute structurally similar bisphenols like BPS or BPF that raise similar concerns.

A 2021 study by the Technical University of Denmark identified over 100 chemicals in plastic toys that pose possible health risks to children. Babies are particularly vulnerable because their bodies are still developing the metabolic pathways needed to process and eliminate toxins, meaning even low-level exposures can matter more than they would in adults.

Food-grade silicone is a fundamentally different class of material. It is derived from silica — essentially processed sand — rather than petroleum-based polymers. According to studies by the FDA and EFSA, food-grade and medical-grade silicone are inert and do not react with food or bodily fluids. It contains no BPA, phthalates, PVC, or lead. When silicone meets FDA and/or LFGB food-contact standards, it has been tested to confirm it won’t release unwanted substances during normal mouthing use.

One nuance worth knowing: not all silicone is equivalent. Lower-grade or poorly cured silicone may contain fillers that reduce purity, and under prolonged extreme heat (above 200°C), low-grade silicone could potentially release trace volatile compounds. High-quality, properly cured food-grade silicone is far less likely to pose these risks. A simple field test: pinch and twist the silicone slightly. If it turns white or discolored under tension, it likely contains fillers and is lower quality. Pure, high-grade silicone retains its color.

Durability: Which One Actually Holds Up to a Baby

Babies are not gentle with their teethers. They drop them on tile floors, gnaw with surprising force, and subject the same toy to hundreds of chewing cycles over weeks. On this front, the materials diverge sharply.

Plastic teethers tend to wear down faster. Repeated impact and chewing can create micro-cracks and surface degradation, which does two things: it creates potential sharp edges, and it increases the surface area available for bacterial colonization. Gel-filled plastic teethers carry an additional risk — they can burst under forceful chewing, creating an ingestion hazard.

Food-grade silicone is tear-resistant and retains its shape and texture even after extended use. Its polymer structure gives it a flexible, give-and-bounce-back feel, so it can handle squeezing, tugging, and gnawing without cracking or crumbling. High-quality silicone does not lose its shape when boiled or steamed, which means it survives the sterilization process that would warp many plastics. In practical terms, a well-made silicone teether can last through the entire teething period — and in some cases, multiple children.

Sterilization: The Hygiene Gap

A teether that falls on the floor at a playground needs to be properly cleaned before it goes back in your baby’s mouth. How a material handles sterilization is a practical safety question, not just a hygiene preference.

Silicone is non-porous, meaning bacteria, mold, and mildew cannot embed in the surface the way they can in materials with micro-cracks or porous structures. High-quality food-grade silicone teethers can be boiled in water for a few minutes, run through a steam sterilizer, or washed on the top rack of a dishwasher — all without deformation. This heat tolerance is a direct result of silicone’s chemical stability. Plastic teethers, by contrast, may warp or release micro-compounds under high heat. Many cannot safely go into a steam sterilizer, and gel-filled varieties cannot be boiled at all without risk of bursting.

The one-piece construction common in quality silicone teethers also matters here: no seams, no joins, no hollow interiors where bacteria can accumulate and resist cleaning.

What to Look For When Buying

The material label is only a starting point. Here’s what actually separates a safe teether from a risky one, regardless of what the packaging says:

Certification matters more than claims. Look for FDA food-contact compliance (US) or LFGB certification (European standard, often considered more stringent). Products that cite CPSC and CPSIA compliance have been tested against US consumer product safety standards. Vague “non-toxic” language without certification backing is a marketing term, not a safety guarantee.

One-piece construction reduces risk. Multi-piece teethers with detachable parts or beads introduce choking hazards and cleaning challenges. A single-mold silicone teether has no seams where bacteria can hide and no small parts that can come loose.

Avoid gel-filled designs. These are typically plastic-shelled with liquid interiors. They cannot be boiled, and forceful chewing can cause them to burst.

Check the ink, too. Some teethers use surface-applied paints or dyes that can flake off. Water-based, food-safe inks injected into the silicone body — rather than painted on the surface — are the safer approach.

Loulou Lollipop’s silicone teethers are made from 100% food-grade silicone and are free of BPA, PVC, phthalates, lead, and cadmium — tested to exceed US CPSC and CPSIA safety requirements. The brand uses water-based, food-safe inks injected into the silicone rather than applied on top, which eliminates the flaking risk. Their silicone teether sets pair a textured teether with a clip designed to keep it within reach — a practical detail that reduces how often a teether ends up on the floor in the first place.

The Verdict

For parents choosing between food-grade silicone and plastic teething toys, the data points in one direction. Plastic carries a higher and harder-to-verify chemical risk, degrades faster under the chewing and sterilization demands of real-world baby use, and limits your cleaning options. Food-grade silicone — specifically certified, high-quality, one-piece construction — avoids the BPA and phthalate concerns entirely, holds up to repeated sterilization without warping, and has a non-porous surface that resists bacterial buildup.

The caveats are real but manageable: not all silicone is equal, so certification and brand reputation matter. A silicone teether from an unverified manufacturer with no third-party testing is not automatically safer than a well-tested plastic alternative. But when you’re comparing certified food-grade silicone against standard plastic — the material most budget teethers are made from — silicone wins on every dimension that matters for infant safety.

If your baby is in the thick of teething, the material choice is worth getting right. The teether is probably the most-mouthed object in your baby’s day. Choosing one made from certified, food-grade silicone with no surface-applied dyes and a one-piece design removes a meaningful category of risk — without requiring any trade-off in function or durability.
