The Complete Australian Guide to Sensory Chew Necklaces
How to choose a safe, effective chew necklace for your child — or yourself — by chewer type, texture and setting. Written for Australian families and the occupational therapists who support them.
If your child chews their shirt collars to shreds, gnaws pencils to splinters, or bites their nails raw, you are not alone — and there is a practical, well-established tool that can help redirect it: the sensory chew necklace.
This guide explains what chew necklaces are, who they help and why, and — most importantly — how to choose the right one, because the wrong firmness or style is the most common reason a chew tool ends up unused in a drawer.
A note on scope: This is general information, not medical or therapeutic advice. Every person’s sensory needs are different. If you are unsure what is right, an occupational therapist (OT) is the best person to ask.
What is a chew necklace?
A chew necklace — sometimes called chewelry — is a wearable tool, usually a silicone pendant on a cord, designed to be safely chewed. It gives the mouth something durable, non-toxic and socially discreet to work on, instead of clothing, pencils, fingers or other unsafe objects.
They are worn by children, teenagers and adults. Despite the playful designs many come in, chewing is not babyish — it is a normal form of sensory regulation that many people rely on throughout life.
Why do people chew? And why a chew tool helps
Chewing provides oral sensory input and proprioceptive feedback to the jaw — the deep-pressure sensation muscles and joints send to the brain. For many people that input is calming, organising and focusing. It is a form of stimming, and like other stims it serves a real purpose: regulating arousal, easing anxiety and helping concentration.
People who benefit from a chew necklace often include those who:
- are autistic, have ADHD, or have a sensory processing difference (SPD)
- seek oral input — chewing clothing, pencils, hair, fingers or nails
- need help settling fidgety energy or focusing (at school, in meetings, while studying)
- experience anxiety and find chewing grounding
- are teething (for the youngest children, with appropriate supervision)
The goal is not to stop the chewing — it is to redirect it to something safe. Trying to suppress the urge usually backfires; giving it a healthy outlet works far better.
How to choose the right chew necklace
This is where most buying decisions go wrong. Match the tool to the chewer, not to the design.
1. Match the firmness to how hard they chew
This is the most important factor. Chew tools are generally graded by chewer intensity:
- Mild chewers — gentle, occasional chewing; prefer softer, more flexible material.
- Moderate chewers — regular, firmer chewing; need medium-firmness silicone that holds up but still gives.
- Aggressive or strong chewers — bite down hard and can destroy soft tools quickly; need thick, high-resistance designs built to last.
Give a soft tool to a strong chewer and it will be bitten through in days (a choking risk). Give a hard tool to a mild chewer and it may feel unpleasant and go unused. When in doubt, start in the middle and adjust.
2. Consider texture
Some people find smooth surfaces calming; others crave texture for extra oral feedback. Designs like our textured Oreo cookie pendant suit those who want more feedback, while a smoother shape suits those who do not.
3. Pick the right form factor for the setting
Chew necklaces are not the only option, and the best choice depends on where it will be used:
- Pendant necklaces — hands-free, always within reach; the classic all-rounder.
- Chewable bangles or bracelets — discreet, good for those who do not like things at their neck.
- Pencil toppers — fit on a pencil for the classroom; great for kids who chew while writing.
- Handheld chews — held or kept in a pocket; suit people who prefer access on demand.
For school-aged kids and adults, discretion matters. A subtle design they are happy to wear in class or at work is one they will actually use.
4. Think about age and independence
Younger children need close supervision. Older kids, teens and adults often want grown-up, low-key designs rather than bright character shapes — and there are plenty available.
Safety: read this before you buy
Chew tools are safe when chosen and used correctly. The essentials:
- Food-grade silicone, free of BPA, PVC, phthalates and lead. Do not compromise on this — it goes in the mouth.
- Breakaway clasp. A good chew necklace clasp releases under pressure so the cord cannot become a strangulation hazard. Non-negotiable for a worn tool.
- Supervise, especially with young children. Chew tools are not recommended for use while sleeping.
- Inspect regularly and replace when worn. Once a tool shows bite marks deep enough to tear, retire it immediately — a chewed-through tool is a choking hazard.
- Mind the age rating. Small parts mean most chew jewellery is not suitable for children under three without specific, supervised, age-appropriate selection.
Caring for a chew necklace
Hygiene matters with anything chewed daily. Wash regularly with warm soapy water and rinse well; check the manufacturer’s guidance on whether a product is dishwasher- or steriliser-safe. Let it dry fully, and keep an eye on the cord and clasp as well as the pendant.
Where chew tools fit in a sensory routine
Occupational therapists often include oral sensory tools as part of a broader sensory diet — a personalised set of activities and supports that help someone stay regulated through the day. A chew necklace might be one piece of that alongside other strategies.
Because the right choice depends on the individual, an OT can assess oral sensory needs and recommend the firmness, texture and format most likely to help. If your child already sees an OT, ask them.
NDIS and chew tools in Australia
For NDIS participants, sensory and oral-motor tools can sometimes be funded as low-cost consumables or assistive technology, depending on your plan and goals. Funding is individual and rules change, so check with your support coordinator, plan manager or OT about what your plan covers before purchasing. (General information only, not funding advice.)
Frequently asked questions
Do chew necklaces actually work?
For many people who seek oral input, yes — they provide a safe, satisfying outlet that can support calm and focus. They are not a cure for anything; they are a practical tool that helps redirect a natural urge.
What age are they for?
Children through to adults. Match the firmness and design to the individual, and follow the age and supervision guidance above. Most chew jewellery is not suitable for under-threes without careful, supervised selection.
How do I introduce one to my child?
Make it available without pressure. Model it calmly, let them explore it, and let them choose a colour or design they like — ownership helps adoption. If one firmness or style does not suit, try another.
Will the school allow it?
Many Australian schools are familiar with chew tools as a recognised support. A discreet design helps, and a quick word with the teacher (and, if relevant, a note from your OT) usually smooths the way.
How long does one last?
It depends entirely on chewer intensity. Strong chewers may go through tools quickly — which is why matching firmness and inspecting regularly matters. Treat them as consumables and replace them before they wear through.
