Every school shirt comes home with a wet, chewed collar. Pencils are covered in teeth marks, sleeves are stretched out, and you often find your child chewing on toys, erasers or even their own fingers. They are well past the teething stage, so you wonder why the chewing has not stopped and whether it means something more.
Why Some Children Keep Chewing
Chewing gives strong input to the jaw and mouth, which many children find calming and organising. When a child is anxious, bored, concentrating hard or overwhelmed, chewing can help them feel settled. Some children also seek more oral sensory input than others and simply need more of it to feel comfortable. The chewing is not a bad habit in the usual sense. It is often the child's own way of regulating their body.
You may notice the chewing increases at specific times, such as during tests, in a noisy classroom, while watching television or when trying to fall asleep. These patterns are useful clues. They show whether your child is using chewing mainly to calm down, to stay alert and focused, or simply out of habit, and each of these needs a slightly different approach at home and at school.
Signs It May Be Sensory Seeking
- Chews more when concentrating, tired or stressed.
- Prefers very crunchy or chewy foods.
- Also seeks other strong input like jumping, crashing or tight hugs.
- Finds it hard to sit still or focus without something in their mouth.
- Chewing continues even when you remove objects and remind them.
What You Can Try at Home
- Offer safe chew options, such as chewable necklaces or pencil toppers made for children.
- Include crunchy snacks like carrots, apples or roasted chana.
- Give drinks through a thick straw or sports bottle for extra oral work.
- Add blowing activities like bubbles, whistles or blowing cotton balls across a table.
- Build in movement breaks during homework and screen time.
What Tends to Make It Worse
Scolding or constantly pulling items out of a child's mouth often increases anxiety, which can lead to more chewing. Long periods of sitting, boredom or noisy environments can also increase the need. Replacing unsafe items with safe alternatives, rather than simply stopping the behaviour, usually works much better, and it also protects your child's teeth and health in the meantime.
When It Is Worth an Occupational Therapy Assessment
Some mouthing of objects is normal in toddlers. It is worth an assessment if chewing is frequent in an older child, is damaging clothes and belongings, involves unsafe items, or comes with other sensory, attention or behaviour difficulties. If your child eats non-food items like mud, chalk or paper, speak to your paediatrician as well. An occupational therapist can assess your child's sensory needs and create a safe, practical plan. Our sensory processing therapy page explains how this assessment works.
Frequently Asked Questions
Is it normal for a school-age child to chew on things?
Occasional chewing on a pencil is common. Frequent chewing on clothes, toys and other objects in an older child often suggests sensory seeking or a way of coping with stress, and is worth understanding better.
Are chew necklaces safe for children?
Chew necklaces designed for children, with breakaway clasps and food-grade materials, are generally safe with supervision. Check them regularly for damage and replace them when worn. An OT can suggest the right type and firmness.
Should I stop my child from chewing?
Rather than stopping it completely, replace unsafe items with safe options and add more calming input during the day. This meets your child's need while protecting their teeth, clothes and health.
Can chewing be linked to anxiety?
Yes. Many children chew more when they are anxious, bored or overwhelmed. If chewing increases in certain situations, noticing the pattern can help you address the underlying stress along with the sensory need.
