Silicone vs Latex Dummies: What Changes in Feel, Care and Everyday Use?
October 9, 2026
If you are trying to choose between silicone and natural rubber latex dummies, the most honest answer is this: neither material is automatically “best” for every baby. What changes day to day is usually the feel (softness and springiness), smell/taste, how the teat looks as it ages, and how careful you need to be with cleaning and checks for wear.
Also worth knowing upfront: material alone does not determine acceptance, safety, or dental outcomes. The dummy’s construction (teat shape and thickness, shield design, ventilation holes), correct size, and following the specific manufacturer’s care instructions matter just as much.
Silicone vs latex at a glance
This quick table covers the differences parents most often notice. Always check your product leaflet and the brand’s official care guidance for the dummy you buy, because heat limits and recommended methods can vary.
| What you notice | Silicone dummy teat | Natural rubber latex dummy teat |
|---|---|---|
| Feel in baby’s mouth | Usually a bit firmer with a consistent shape | Usually softer and more elastic/springy |
| Flexibility | Flexible, but tends to “hold” its moulded form | Very flexible and compressible |
| Smell/taste | Typically neutral | Often has a noticeable natural rubber smell/taste |
| Appearance | Often translucent/clear or evenly coloured | Often honey/amber-toned; may darken or become tacky with age |
| How it ages | Can still wear, tear, or become damaged (especially if bitten); may cloud or weaken over time | More prone to swelling, stickiness, small surface cracks, and faster ageing (heat and light can accelerate this) |
| Cleaning tolerance | Often tolerates higher-heat methods well (product-dependent) | Often more sensitive to high heat and certain sterilising methods (product-dependent) |
| Allergy considerations | Does not contain natural rubber latex proteins | Contains natural rubber latex - avoid if latex allergy is known or suspected |
Practical insight: If your baby refuses a dummy, parents often jump straight to “wrong material”. Before buying three more, check two basics first: the size/age stage and whether the dummy is new (smell/taste changes are strongest when first opened). Material is only one piece of the puzzle.
Feel, flexibility, smell and appearance
How silicone tends to feel
Silicone teats are typically smooth and slightly firmer. Many parents like that the shape feels predictable and stable from one use to the next, especially for orthodontic or positioning designs that rely on the teat holding a specific form.
- Common parent feedback: “It feels a bit firmer, but consistent.”
- Baby acceptance: Some babies prefer that stability; others want something softer.
How natural rubber latex tends to feel
Natural rubber latex is usually softer and more elastic. That can feel “squishier” in the mouth and can compress and rebound quickly when a baby sucks.
- Common parent feedback: “It feels closer to skin and very flexible.”
- Baby acceptance: Some babies settle more easily with the softer feel; others dislike the springiness.
Smell and taste (often the deciding factor)
One of the biggest everyday differences is sensory: natural rubber latex often has a distinct smell/taste. Some babies do not mind it at all; others spit the dummy out immediately. Silicone is generally more neutral in odour and taste.
Appearance
Silicone is often clear or evenly coloured. Latex is often naturally amber-toned and can look darker as it ages. Neither look is “better” - but changes in appearance can be a useful prompt to inspect the teat carefully.
How they change with use
Both materials can deteriorate. What changes is how it tends to show up and how quickly it happens, depending on the baby, cleaning method, and exposure to heat/light.
Typical changes you might see with silicone
- Surface may become cloudy or less clear over time.
- If your baby has teeth, silicone can develop bite marks or tears.
- Over time, any dummy can weaken at stress points (for example, where the teat meets the shield), so checks matter.
Typical changes you might see with latex
- May swell slightly or feel tacky/sticky as it ages.
- Small surface cracks can appear, especially with heat exposure.
- Colour can darken.
Practical insight: A quick daily habit saves time and worry: before each use, give the teat a careful look and a gentle tug in different directions. If you see thinning, tears, stickiness, cracking, or a change that concerns you, replace it and follow the brand’s safety guidance.
Care, cleaning and sterilisation
The right answer here depends on the manufacturer’s instructions for your specific dummy. Different brands use different constructions (one-piece vs multi-part), and guidance can vary by material and design.
In general, parents find silicone simpler for high-heat routines, while latex often needs a bit more caution with heat and method. But it is not safe to assume one “always” tolerates a certain steriliser - check the packaging/leaflet each time.
- After cleaning: let the dummy dry fully, including any crevices, before storing.
- Storage: store clean dummies in a dry, clean container; avoid prolonged direct sunlight/heat, which can age materials faster.
- Do not “revive” a worn teat: if it looks or feels degraded, cleaning harder is not the fix.
If you want step-by-step routines, times, and method comparisons, use our dedicated guides rather than trying to memorise rules from a general comparison article:
- Hygiene: see our dummy cleaning and sterilisation guide.
- Replacement: see our guide on when to replace a dummy and what wear signs to look for.
- Refusal: see our guide on what to do when a baby refuses a dummy.
Practical insight: If you are rotating a few dummies, label or separate them by “in use” and “clean” to avoid re-sterilising repeatedly. Over-handling (extra boiling/sterilising cycles you did not need) can speed up wear for any material.
Safety and allergy considerations
Safety is mostly about using a dummy that meets the relevant safety standard for your market, choosing the correct size/stage, following the brand’s instructions, and replacing at the first sign of damage.
Latex allergy: what parents should know
Natural rubber latex contains proteins that can trigger allergic reactions in some people. If your baby has a known or suspected latex allergy (or there is strong family history and you have been advised to avoid latex), choose a non-latex option and speak to your health professional for individual advice.
For health information on latex allergy, see: Allergy UK’s guide to rubber latex allergy.
Silicone and sensitivity
Silicone does not contain natural rubber latex proteins, which is one reason many families choose it. That said, any baby item can still cause irritation if it is the wrong size, traps moisture, or is not cleaned and dried properly - so fit and care still matter.
Oral development: what material can and can’t do
Parents often ask which material is “better for teeth”. Material choice can affect feel and how well a teat keeps its intended shape, but oral outcomes are more strongly influenced by overall dummy design, size, how long a dummy is used each day, and how long dummy use continues as a child grows.
In practical terms:
- Silicone can be a good match for designs that depend on the teat maintaining a specific geometry, because it typically holds a moulded form consistently.
- Latex can feel softer and more compressible, which some babies prefer, but it may change texture and shape more noticeably as it ages.
At LUU Kids, our flagship LUU positioning pacifier is made in silicone and offered in age stages (0-3m, 3-6m, 6m+). The positioning concept relates to the pacifier’s nipple construction and intended tongue space; the fact it is silicone is primarily about delivering a consistent, durable shape for that specific design - not a promise that silicone alone guarantees a particular dental result.
For broader advice on dummy use and teeth, the UK’s oral health guidance for children is a sensible starting point: NHS guide to healthy teeth and gums: children's teeth.
Practical decision examples
Sometimes the easiest way to choose is to match the material to your real routine, not an idealised one.
If your baby is sensitive to smell or keeps spitting it out
Try a silicone option first, because it is typically more neutral in smell/taste. If you do try latex, expect a stronger natural rubber odour when it is new and see if it fades with normal washing (always following the product guidance).
If you need a dummy that holds its shape reliably
Silicone may suit you, especially for orthodontic/positioning designs. If you are considering a positioning design, focus on the brand’s instructions for sizing and use - the shape and correct stage matter.
If you prefer a very soft, elastic feel
Natural rubber latex may be worth trying, as long as latex allergy is not a concern and you are comfortable with potentially more noticeable ageing and more method-specific care guidance.
If nursery/daycare needs straightforward routines
Many parents pick silicone because the care routine is often simpler to standardise. Whichever you choose, send dummies in a clean, labelled container and replace them promptly when worn.
If you are trying to be more mindful about materials
Latex is made from natural rubber, while silicone is synthetic. Environmental impact is broader than just the raw material (manufacturing, durability, how many you get through, and disposal). If sustainability is high on your list, consider how long the dummy lasts in your household and how many you are likely to buy over time.
FAQ
Can I switch my baby from a latex dummy to a silicone dummy (or the other way round)?
Yes. Many babies switch without any issue, but some notice the difference immediately. If your baby refuses the new one, try offering it when they are calm (not very hungry or overtired) and give it a few days. If the old dummy is worn, do not keep using it just because it is familiar.
Why does my latex dummy smell or taste stronger than silicone?
That is common. Natural rubber latex often has a characteristic rubber smell/taste, especially when new. Silicone is usually more neutral. If the smell seems unusually strong or the material feels sticky or degraded, follow the manufacturer’s guidance and replace.
My dummy’s texture changed - is it still safe?
A change in texture can be a sign of ageing or damage. Inspect carefully for stickiness, swelling, thinning, cracks, or tears, and replace at the first sign of deterioration. When in doubt, follow the brand’s safety instructions for that exact product.
Does silicone or latex make a dummy more “orthodontic”?
No. “Orthodontic” or “positioning” relates to the dummy’s design and how it is intended to sit in the mouth, not the material alone. Material can influence how well the teat keeps its designed shape, but you still need the right size/stage and correct use.
Is a “natural” latex dummy automatically safer than silicone?
No. Natural does not automatically mean safer. Safety depends on compliance with safety standards, intact condition (no tears), correct size, and following the manufacturer’s care instructions. Latex also brings specific allergy considerations for some children.
