The Problem Hiding in Plain Sight
Pick up two silicone teethers side by side and they might look identical. Same color, same general shape, same soft give when you press them. But squeeze one of them and it smells faintly of chemicals. Twist the other and the color holds perfectly, no white streaks, no tackiness on your fingertips. One is food-grade silicone. The other is something else entirely.
Silicone has become the go-to material for baby teething toys because, when made correctly, it is genuinely safe. Food-grade silicone is non-toxic, BPA-free, and approved for food contact. It does not leach harmful chemicals, holds up to sterilization, and stays pliable without breaking into pieces a baby could choke on. The issue is that not all silicone sold in baby products is food-grade. Low-grade alternatives — sometimes padded out with cheap fillers — can look almost identical on the shelf, especially in packaging-heavy retail environments or on crowded marketplace listings where you cannot touch the product before you buy.
With the rising popularity of silicone baby products, there is an increasing risk of counterfeit or low-quality items infiltrating the market. These products may contain impurities, harmful chemicals, or substandard materials that pose serious health risks to your child. Knowing what to look for — before the teether ends up in your baby’s mouth — is a practical skill worth having.
The Four Physical Warning Signs
1. Sticky or greasy surface texture
Low-grade silicone may contain fillers, leaving it sticky, oily, or with a chemical smell. These materials are harder to clean and may degrade faster. Run a clean finger across the surface of any teether you are considering. High-quality food-grade silicone feels smooth and slightly matte — almost like a dry rubber. If the surface feels tacky, or if it picks up lint and dust easily, that stickiness probably comes from filler compounds or incomplete curing, not from the silicone itself.
2. A chemical or rubbery smell
Authentic silicone is odorless or has a very faint, neutral smell. High-quality silicone should be odorless. A strong chemical smell may indicate the use of fillers or low-grade materials. This is one of the easiest checks you can do in-store or immediately after opening a package. Hold the teether close and take a slow breath. A faint, neutral scent — or nothing at all — is what you want. A sharp plastic smell, a rubbery chemical odor, or anything that reminds you of a new shower curtain is a red flag worth taking seriously.
3. Color inconsistency or uneven finish
High-quality silicone products exhibit a smooth, matte, or slightly glossy surface with uniform color. Patches of uneven pigmentation, cloudiness in certain areas, or a finish that looks slightly bleached in spots can all suggest the base material was stretched with fillers or that low-grade dyes were used. Some low-quality silicone is bleached to achieve a high-quality appearance, which means visual checks alone are not foolproof — but obvious color inconsistency is still a useful signal.
4. The pinch test
This is the most reliable at-home check. A simple way to check the quality of silicone is the Pinch Test: pinch or twist the silicone product to stretch it slightly. If the silicone turns white or appears discolored, it likely contains fillers and is of lower quality. If it retains its original color, it is pure, high-quality silicone. Poor-quality silicone products may contain fillers or additives to cut costs. These fillers can compromise the safety of the teether, leading to potential health risks. A simple way to check is by stretching the silicone — if it turns white, it may contain fillers. Pure, well-formulated silicone stretches without losing its color. It springs back to its original shape without deforming.
What Those Fillers Actually Are — and Why They Matter
When manufacturers cut costs on silicone, they often do it by mixing in cheaper filler compounds to bulk out the material. Low-grade silicone products can contain plasticizers including phthalates — the very chemicals parents are trying to avoid. These are the same compounds commonly associated with hormonal disruption, which is exactly why parents switched away from older plastic teethers in the first place.
The curing method used during manufacturing also matters more than most people realize. Silicone curing methods play a critical role in its safety and performance. Peroxide curing, while common in lower-quality products, can leave chemical residues that might leach over time. Platinum curing is a safer and preferred method for baby products — this process ensures higher purity and better durability, making it ideal for items like pacifiers, teething toys, and feeding sets. Brands that invest in platinum-cured, food-grade silicone are generally producing a cleaner, more stable product. Those that don’t often won’t mention the curing method at all.
Some silicones are not suitable for human health, particularly low-molecular weight silicones or high-quality silicone that has been filled or mixed with low-quality silicone. Such silicones can actually seep through your skin and build up in your system. The risk is not necessarily acute — one teether is unlikely to cause immediate harm — but a teether is something a baby chews on for months, often daily. Cumulative exposure to even low-level chemical migration is a reasonable concern.
What to Look for on the Label (and What to Ignore)
Certifications are the most reliable shortcut when you cannot physically test a product. Reputable manufacturers comply with international safety standards such as FDA (Food and Drug Administration), which ensures that silicone products are non-toxic and safe for oral use, and the CPSC (Consumer Product Safety Commission), which regulates baby products for choking hazards and material safety. For products sold in the US, look for explicit CPSIA compliance alongside the food-grade silicone claim.
Beyond US standards, LFGB-grade silicone tends to represent a higher quality product due to its stricter standards. LFGB often enforces stricter limits on the allowable amount of certain substances that can migrate from the silicone into food — even if a substance is tested for in both standards, the acceptable level might be lower for LFGB, ensuring a higher level of safety. Seeing LFGB certification on a teether is a meaningful signal, not just marketing language.
But be cautious about vague claims. Phrases like “BPA-free” and “non-toxic” on their own are almost meaningless without supporting certifications, because they describe what a product does not contain rather than confirming what it does. You can view the report information, which includes the testing institution and testing items, then verify the information through an authoritative third-party institution. If it is a formal FDA or LFGB report, you can trace its origin. However, if you find that the report cannot be verified, then the certification is fake — and this also means the silicone is not standard. Brands that have nothing to hide will point you to third-party test reports. Brands that don’t offer this tend to bury the material details entirely.
Also worth noting: price is a rough but real indicator. The price is a way to help you differentiate between regular silicone and food-grade silicone. Food-grade silicone is more expensive because it uses better raw silicone. If the silicone supplier’s price is much lower than the normal price, the supplier may use regular silicone to pass off as food-grade silicone. A teether priced at a fraction of comparable products from established brands is probably cutting corners somewhere — and materials are usually the first place that happens.
A Practical Checklist Before You Buy
Putting it all together, here is what to do before handing any new teether to your baby:
- Smell it first. No smell, or a faint neutral one, is good. Any chemical or rubbery odor is not.
- Run a finger across the surface. It should feel smooth and dry, not tacky or oily.
- Do the pinch test. Twist a section firmly. If white streaks appear, there are fillers present.
- Check the color uniformity. Uneven patches, cloudiness, or bleached-looking areas suggest low-grade materials.
- Look for certifications you can verify. FDA compliance and CPSIA testing are the US baseline. LFGB is a meaningful upgrade.
- Check the construction. Choose one-piece molded silicone designs with no cords, small parts, or glued joints. Multi-part teethers with beads on strings introduce both material and structural risks.
- Replace damaged teethers immediately. Regularly check for signs of wear and tear, such as cracks or tears, and replace the teether if necessary. Even good silicone can degrade with heavy use.
Loulou Lollipop’s silicone teether collection is made from 100% food-grade silicone, free of BPA, PVC, phthalates, lead, and cadmium, and independently tested to meet CPSIA standards. The teethers are molded as single pieces with no loose components — which means they pass the construction check before you even open the box. For parents who want to skip the guesswork, that kind of material transparency is exactly what to look for.
