Silicone vs. Other Teether Materials: A Parent's Comparison

Quick answer

For most babies, food-grade silicone is the best all-round teether material: it is soft on gums, free from BPA and phthalates, and easy to clean. Natural rubber is a close second but can cost more and may have a stronger smell. Wood and other hard materials suit older children who need pressure, but they are not ideal for young babies. If you want a safe, versatile option, start with silicone.

When your baby starts chewing on everything in sight, the teether you choose matters for comfort, safety, and your own sanity. The material affects how it feels on sore gums, how you clean it, and how long it lasts. This comparison looks at silicone, natural rubber, wood, and other common teether materials using the facts we have on hand.

We will not invent test results or safety claims. Instead, we will explain the trade-offs based on what manufacturers and health authorities generally say, and point to specific Jellystone Designs products that use food-grade silicone so you can see how those benefits play out in real shapes and sizes.

Silicone: the soft, safe default

Silicone teethers are made from a synthetic polymer that is generally considered safe for babies when it is food-grade and free from BPA and phthalates. It has a soft, slightly squishy feel that is gentle on sore gums, and it does not absorb liquids, so it resists bacteria and mold better than some porous materials. Most silicone teethers can be washed with warm soapy water or put in the dishwasher, which makes cleanup simple.

Silicone also holds up well to repeated chewing and can be molded into many shapes, from simple rings to detailed pendants. That versatility is why you see silicone used in products like the Koala Teether, which is described as non-toxic, BPA-free, and phthalate-free. The main trade-off is that silicone can tear if a child chews aggressively for a long time, so you need to check for wear regularly.

• Look for the words food-grade silicone and BPA-free on the label.
• Check for rips or tears every few weeks, especially if your child is a strong chewer.

Natural rubber: soft but with caveats

Natural rubber teethers come from the sap of rubber trees. They are soft, flexible, and biodegradable, which appeals to parents looking for a more natural option. Like silicone, natural rubber is gentle on gums and can be molded into fun shapes. However, natural rubber can have a distinct smell that some babies dislike, and it may degrade faster than silicone, especially if left in sunlight or washed at high temperatures.

Another consideration is allergies. Some children are sensitive to latex proteins that can be present in natural rubber, though many teethers are labeled as hypoallergenic. If your baby has a known latex allergy, silicone is a safer bet. Natural rubber teethers are often more expensive than silicone, and they may not be as widely available in complex shapes.

• If you choose natural rubber, check that it is labeled hypoallergenic and free from added chemicals.
• Replace natural rubber teethers at the first sign of cracking or stickiness.

Wood and other hard materials: for older chewers

Wooden teethers are sturdy, naturally antibacterial (though not sterile), and free from synthetic chemicals if left unfinished or finished with food-safe oil. They provide firm pressure that can be soothing for older babies and toddlers who are working on molars. However, wood is hard, so it is not suitable for young babies who might bang their gums or chip a tooth. It also should not be soaked in water, as that can cause cracking and splintering.

Other hard materials include food-grade silicone that is firm rather than soft, or thermoplastic elastomers (TPE). These can offer a middle ground, but they vary widely in quality. Always check that the material is free from BPA, phthalates, and heavy metals. For the youngest babies, soft materials like silicone are generally the safer choice because they reduce the risk of injury.

• Inspect wooden teethers for splinters or cracks before each use.
• Avoid wooden teethers for babies under 6 months or those who cannot sit up without support.

How to weigh safety and practicality

Safety is not just about the material; it is also about how the teether is made and used. Any teether can become a hazard if it breaks into small pieces, so regular inspection is key. Silicone and natural rubber are both soft enough to be safe for young gums, but silicone has the edge in durability and ease of cleaning. Wood is durable but requires more care and is not ideal for early teething.

Practicality matters too. If you need a teether that can go in the dishwasher, silicone is usually the easiest. If you want a natural material that will biodegrade, natural rubber is appealing but may need replacing sooner. For a balance of safety, cost, and convenience, food-grade silicone is hard to beat.

• No teether material is indestructible; check for wear often.
• Follow the manufacturer's cleaning instructions to avoid damaging the material.

Trade-offs at a glance

• Silicone: Soft, durable, easy to clean, and free from BPA and phthalates. Can tear with heavy chewing over time. Best for most babies and toddlers; check regularly for wear.
• Natural rubber: Soft, biodegradable, and gentle on gums. May have a smell, degrade faster, and cost more. Not ideal for latex-allergic babies. Choose if you prefer a natural material and are willing to replace it more often.
• Wood: Firm, durable, and naturally antibacterial. Hard on young gums, not water-friendly, and can splinter if damaged. Better for older children who need firm pressure and can use it safely.

Silicone teethers in the Jellystone Designs range

• Koala Teether: Made from non-toxic silicone, the Koala Teether is BPA-free, phthalate-free, and non-toxic. It has tactile elements on the back for added sensory fun. This shows how silicone can be both safe and engaging, with a soft texture that is gentle on gums and easy to hold for tiny hands.
• Snowflake Pendant: The silicone Snowflake pendant is recommended by Occupational Therapists as a tool your child can use independently to develop effective control of their nervous system. Silicone can be shaped into wearable pendants that provide a safe chewing option for older children who need sensory regulation on the go.
• Rainbow Stacker and Teether Toy: Babies love chewing on the soothing silicone rings, and older children practice hand-eye coordination by stacking the rings. This demonstrates the versatility of silicone: it works as a teether for babies and a developmental toy for older children, extending its useful life.

Which teether material is right for your child?

Best for

• Babies from 3 months who need a soft, safe teether that is easy to clean.
• Parents who want a material that is free from BPA and phthalates and can go in the dishwasher.
• Children who benefit from sensory tools like chew pendants for self-regulation.

Not for

• Children with a known latex allergy if considering natural rubber.
• Babies under 6 months if considering wooden teethers, due to hardness and splinter risk.
• Heavy chewers who need a material that will never show wear; all teethers need replacing eventually.

Silicone offers the best balance of safety, comfort, and convenience for most families. Natural rubber and wood have their places, but they come with trade-offs in durability, cost, or suitability for young babies. Whichever you choose, inspect it often and replace it at the first sign of damage. If you want to start with a trusted silicone option, explore the Jellystone Designs range of teethers and chew pendants.
