The Material Question Pediatric Dentists Keep Answering
Walk into any pediatric dental office and ask about teething toys, and you’ll likely hear the same short list of approved materials: food-grade silicone, natural rubber, and untreated hardwood. That’s not a coincidence. Those three materials have earned their place through a combination of chemical safety, durability, and ease of cleaning — qualities that matter a lot when a product spends hours in an infant’s mouth.
Of the three, food-grade silicone tends to come out on top for most families. It’s worth understanding exactly why, because the teething product market in 2026 is enormous and largely unregulated, which means the burden of identifying safe products falls almost entirely on parents.
Pediatric dentists consistently recommend teethers made from food-grade silicone or natural rubber, free of BPA, phthalates, PVC, parabens, and synthetic dyes. That’s the baseline. Everything else — shape, color, texture, price — is secondary to whether the material itself is safe for an infant who will chew on it for months.
What Makes Silicone Safer Than Plastic
Silicone is derived from silica, a compound found in sand. That origin matters because it means the material doesn’t carry the chemical baggage that comes with conventional plastics. Food-grade silicone is widely regarded as the safest option when it comes to non-toxic teethers — it’s not plastic, but shares useful properties like flexibility and water resistance, while being gentle on baby gums and free of BPAs and phthalates.
The contrast with plastic is significant. A 2021 study by the Technical University of Denmark found over 100 chemicals in plastic toys that pose possible health risks to children. Soft, inexpensive plastic teethers are particularly prone to containing these compounds. Even products labeled “BPA-free” aren’t automatically safe — a significant number of products labeled “BPA-free” were also found to contain BPA, according to studies examining baby teething toys for the presence of BPA, endocrine-disrupting chemicals, and other potentially toxic substances.
Silicone sidesteps most of those concerns. The silicone used in teething products is often naturally antibacterial, doesn’t hold onto foreign odors or fragrances, and is BPA-free, PVC-free, phthalate-free, and latex-free. And because it’s non-porous, it won’t trap bacteria the way porous materials can — a meaningful advantage for something that gets dropped on the floor, sucked on, and handed back repeatedly throughout the day.
For families with latex allergies, silicone is also the obvious alternative to natural rubber. If a parent or baby has a latex allergy, silicone is the ideal alternative to natural rubber toys and teethers.
The Specific Criteria Dentists Use When Evaluating Teethers
Material is the starting point, but pediatric dentists apply a few additional criteria when recommending a teether. Design, construction, and cleanability all factor in.
One-piece construction ranks near the top of every safety checklist. 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. Silicone’s natural flexibility and durability make one-piece designs practical; the material can withstand sustained chewing without cracking or shedding fragments.
Texture matters too, and not just for entertainment. Dr. Shamin Makvandi, principal dentist at DentiFlow Dentistry, advises looking for a toy made of non-toxic and durable material such as natural rubber, silicone, or wood, and emphasizes that varied surfaces — bumps, ridges, and grooves — stimulate the gums and emerging teeth, providing both comfort and developmental input. Different textures can also reach different parts of the mouth, which becomes relevant as the teething sequence progresses from front incisors through to first and second molars.
Cleanability rounds out the list. A constantly wet teething toy provides a conducive environment for mold and bacteria; teething toys should be durable enough to endure a cleaning process, either in a dishwasher or with dish soap and hot water. Food-grade silicone handles both methods without degrading — an advantage over natural rubber, which tends to age faster when exposed to repeated sterilization.
One thing pediatric dentists consistently warn against: liquid-filled or gel-filled teethers. Freezing or chilling a liquid-filled toy can help offer relief, but a baby’s sharp teeth and strong bite could penetrate the exterior material, causing the liquid or gel to leak — making it simply safer to avoid these types of products altogether. Solid silicone teethers eliminate that risk entirely.
And on the topic of temperature: chilled teethers from the refrigerator are safe and effective; frozen, solid teethers are too hard and can damage delicate gum tissue. The fridge, not the freezer, is the right call.
What Pediatric Dentists Say to Avoid
The list of what not to use is arguably as useful as the recommended materials list. A few categories come up repeatedly in pediatric dental guidance.
Teething jewelry — amber necklaces, silicone bead bracelets — gets the most consistent warnings. The American Academy of Pediatrics and the FDA warn that all teething jewelry poses a choking and strangulation hazard for infants. There’s also no clinical evidence that amber has any pain-relieving effect on teething gums.
Numbing gels are another category to skip. Some parents turn to over-the-counter numbing gels to ease gum pain, but these are no longer considered safe — ingredients like benzocaine or lidocaine can cause serious health complications in babies and toddlers. The FDA has issued explicit warnings against benzocaine-based products for children under two.
Homeopathic teething tablets have also drawn scrutiny from regulators and pediatric organizations. The FDA has previously warned about inconsistent belladonna levels in some of these products, and the American Academy of Pediatrics recommends against them.
The safer path is physical comfort — a chilled silicone teether, a gentle gum massage with a clean finger, or a cold damp washcloth — rather than any product that introduces chemicals or loose parts into the equation.
How to Read a Teether Label (and When to Be Skeptical)
The phrase “non-toxic” on a teether package is a marketing claim, not a regulated standard. The same goes for “natural” and, in some cases, “BPA-free.” What actually matters is whether the product specifies food-grade or medical-grade silicone, and whether it has been tested by an accredited third-party laboratory against recognized safety standards.
Not all silicone is created equal — always seek out products labeled as food-grade or medical-grade. Products that have been tested to Consumer Product Safety Commission (CPSC) standards and are certified free of BPA, PVC, phthalates, lead, and cadmium offer a meaningfully higher level of assurance than vague “non-toxic” labeling.
Loulou Lollipop’s silicone teether collection is built around exactly this standard. Every teether toy and ring they sell is safety-tested by a leading third-party laboratory to ensure they are entirely free of BPA, PVC, phthalates, lead, cadmium, and other toxic substances, and that they comply with Consumer Product Safety Commission (CPSC) regulations. Their teethers are made from 100% food-grade silicone and come in a range of shapes and textures — including character designs with multiple chewing surfaces suited to different stages of the teething sequence.
For parents also navigating mealtime alongside teething, it’s worth knowing that the same material standards apply across Loulou Lollipop’s baby feeding collection — food-grade silicone throughout, third-party tested, and free of the same list of harmful compounds. The brand holds B Corp certification and ISO 9001 and ISO 14001 certifications, which speak to consistent manufacturing and environmental standards across their product lines.
When comparing options, the questions worth asking are simple: Is the silicone food-grade? Has it been third-party tested? Is the construction one-piece? If a brand can answer yes to all three with documentation to back it up, that’s a product worth considering.
The Bottom Line on Silicone and Pediatric Dental Guidance
Pediatric dentists don’t recommend silicone teethers because they’re trendy. They recommend them because the material profile holds up under scrutiny — chemically inert, non-porous, durable, easy to sterilize, and free of the compounds that raise concern in conventional plastics.
Silicone teething rings are a popular choice due to their durability and flexibility — soft enough to be gentle on tender gums but firm enough to provide effective relief. That balance is harder to achieve than it sounds, and it’s why silicone has become the default recommendation across pediatric dental practices.
For parents working through the teething stage in 2026, the decision framework is actually straightforward: prioritize food-grade silicone or natural rubber (with latex allergy awareness), confirm one-piece construction, verify third-party safety testing, and skip anything with beads, liquid fill, or numbing agents. The teething phase is temporary. The habits around material safety — reading labels, asking for certifications, choosing tested products — tend to stick around a lot longer.
