Why Silicone is the #1 Material for Baby Teething Toys
When babies teethe, they chew — hard. The ideal teething toy material must be completely safe if ingested (even though it should not be), durable enough to withstand months of aggressive chewing, and soft enough to not damage emerging teeth. Silicone is the only material that meets all these criteria.
Key Safety Standards for Silicone Baby Teething Toys
FDA (USA) — 21 CFR 177.2600
Mandatory for US market. The silicone must pass extractables testing in water, alcohol, and hexane simulants. Additional requirements:
- CPSIA compliance: Lead < 100 ppm, Phthalates < 0.1%, BPA non-detectable
- Third-party testing: Must be tested by CPSC-accepted laboratory
- Tracking label: Permanent mark with manufacturer, date, and location
LFGB (Germany) — § 30/31
The strictest food-contact standard globally. In addition to extractables, LFGB requires sensory testing (no taste/smell transfer to food).
EN71 (European Union)
Mandatory for EU market. EN71-1 (mechanical), EN71-2 (flammability), EN71-3 (migration of heavy metals).
Design Best Practices for Silicone Teething Toys
- Multiple textures: Combine smooth, bumpy, and ridged surfaces for different teething stages
- Easy-grip shapes: Rings, handles, or hollow designs that small hands can grasp
- Size appropriate: Must be large enough to not be a choking hazard (>4cm in any dimension)
- Hollow construction: Reduces weight and material cost; must have vent holes to prevent suction entrapment
- Clip/strap compatibility: Include holes or loops for pacifier clips (prevents dropping)
Material Specifications for Baby Teething Toys
| Parameter | Specification | Test Method |
|---|---|---|
| Silicone type | LSR (Liquid Silicone Rubber) | Platinum-cured preferred |
| Hardness (Shore A) | 30-50 | ASTM D2240 |
| Tear strength | >25 N/mm | ASTM D624 |
| Extractables (LFGB) | Pass | LFGB § 30/31 |
| BPA/Phthalates | Non-detectable | CPSIA/REACH SVHC |
Manufacturing Process: LSR Injection Molding
Baby teething toys are almost exclusively manufactured using LSR (Liquid Silicone Rubber) injection molding because:
- Flash-free: No parting line flash that could be a choking hazard
- Excellent surface finish: Smooth, skin-safe surface
- Consistent cure: Automated metering eliminates human error
- Cleanroom compatible: Can be molded in cleanroom environment
Common Design and Safety Pitfalls
Choking Hazard from Small Parts
Any attached components (bells, rattles, plastic rings) must be securely retained. Use ultrasonic welding or overmolding to eliminate small-part detachment risk.
Inadequate Wall Thickness
Walls < 2mm may tear under aggressive chewing. Specify minimum 2.5mm wall thickness for teething toys.
Incorrect Hardness
Shore A 20-30 is too soft (tears easily); Shore A 60+ is too hard (uncomfortable for baby). Target Shore A 35-45.
Packaging and Labeling Requirements
Baby products have strict packaging and labeling requirements:
- Age grading: “For ages 3 months+” clearly marked
- Care instructions: Boiling/sterilization instructions
- Material identification: “100% Food-Grade Silicone” on packaging
- Country of origin: “Made in China” (US Customs requirement)
- Warning statements: “Inspect before each use. Discard if damaged.”

Frequently Asked Questions
Is silicone safe for baby products?
Yes. Medical-grade and food-grade silicone is BPA-free, phthalate-free, and hypoallergenic. It meets FDA, EU EN 14350, and CPSIA standards. Silicone baby products including bottle nipples, pacifiers, teethers, and bibs are widely recommended by pediatricians.
Are silicone baby bottles safe?
Silicone baby bottles are considered one of the safest options available. They are BPA-free, shatterproof, heat-resistant, and do not leach chemicals. Medical-grade silicone is used in hospital settings and meets strict safety certifications.
What certifications should silicone baby products have?
Key certifications include FDA 21 CFR 177.2600 (US), EU 10/2011 (Europe), EN 14350 (baby feeding), CPSIA (US children products), and SGS testing reports. Reputable manufacturers should provide current certificates upon request.
