If you’ve ever heard your child grinding their teeth at night, you’re not alone. Teeth grinding also known as bruxism is surprisingly common among children in Melbourne and across Australia. While it’s often harmless and temporary, persistent grinding can wear down baby teeth, cause jaw discomfort, and disrupt sleep.
Understanding why kids grind their teeth, when it becomes a concern, and how to manage it can help protect your child’s long-term oral health.
What Is Teeth Grinding (Bruxism)?
Bruxism is the involuntary grinding, clenching, or gnashing of teeth. It can happen:
- During sleep (sleep bruxism)
- When awake (awake bruxism)
In children, bruxism often occurs during deep sleep phases or when they are concentrating, anxious, or overstimulated.
Most children outgrow it,but monitoring and early dental checks help prevent complications.
Common Causes of Teeth Grinding in Kids
Bruxism can develop for several reasons some physical, some emotional, and some developmental.
1. Teething or Eruption of New Teeth
When baby teeth or permanent teeth come through, children may grind to:
- Relieve pressure
- Soothe gum discomfort
- Explore new sensations
This type of grinding is generally temporary.
2. Bite or Jaw Alignment Issues
If the top and bottom teeth don’t fit together correctly, your child may subconsciously grind to “correct” the bite.
Misalignment such as:
- Overbite
- Underbite
- Crossbite
- Crowding
can contribute to grinding.
3. Stress, Anxiety, or Emotional Changes
Kids may grind their teeth during periods of:
- School pressure
- Exams
- Family changes
- Nightmares
- Anxiety
Grinding becomes a physical outlet for emotional tension.
4. Sleep Disorders
Children with sleep-related issues may also grind their teeth.
These include:
- Snoring
- Sleep apnoea
- Mouth breathing
- Restless sleep
Addressing sleep issues often significantly reduces grinding.
5. Medical or Developmental Conditions
Bruxism is more common in children with:
- ADHD
- Autism spectrum disorder (ASD)
- Sensory processing sensitivities
However, each child is different, and grinding may vary in intensity.
6. Habits or Stimulation
Some children grind their teeth simply out of habit or because they enjoy the sensation, especially during quiet activities.
Signs Your Child May Be Grinding Their Teeth
Not all grinding is loud. Look for symptoms such as:
- Chipped or worn baby teeth
- Sensitivity to hot or cold
- Jaw or facial discomfort
- Morning headaches
- Clicking sounds from the jaw
- Disturbed sleep
- Chewing on objects more than usual
A dental examination can confirm if bruxism is causing damage.
Is Teeth Grinding Harmful for Kids?
Occasional grinding, especially during teething, is usually harmless.
However, persistent grinding can lead to:
- Worn-down baby teeth
- Cracked or chipped teeth
- Increased sensitivity
- Jaw strain or TMJ issues
- Difficulty chewing
- Disturbed sleep patterns
In rare cases, prolonged grinding may also affect the eruption of permanent teeth.
Early intervention reduces the risk of complications.
How Dentists Diagnose Bruxism in Children?
At Melbourne Family Dentist, we examine:
- Tooth wear patterns
- Jaw movement
- Bite alignment
- Gum and soft tissue condition
- Sleep-related symptoms
- Emotional or behavioural triggers
This helps identify the underlying cause and tailor a treatment approach.
Solutions for Kids Grinding Their Teeth
Treatment depends on what’s causing the grinding. Here are the most effective strategies:
1. Monitoring (For Mild, Temporary Cases)
If grinding is due to teething or temporary stress, your dentist may simply monitor your child’s teeth during routine check-ups.
2. Managing Stress and Emotions
Create a calming bedtime routine:
- Warm bath
- Reading time
- Soft music
- Relaxation exercises
Encourage children to talk about worries. Emotional reassurance can significantly reduce grinding.
3. Correcting Bite or Alignment Issues
If misalignment is the cause, early orthodontic evaluation may be recommended.
Treatments may include:
- Space maintainers
- Early-phase orthodontics
- Future Invisalign or braces
Alignment correction often eliminates the need for grinding long-term.
4. Improving Sleep Quality
If grinding is linked to sleep problems, improving sleep habits can help:
- Earlier bedtime
- Reduced screen time
- Nasal breathing support
- Treating allergies
- Checking for enlarged tonsils or adenoids
For children with sleep apnoea, referral to a sleep specialist may be needed.
5. Night Guards (For Older Children)
Night guards protect teeth from wear and reduce pressure on the jaw.
They are usually recommended for:
- Children with severe grinding
- Children with permanent molars who show significant wear
- Teens with ongoing bruxism
Night guards are not typically used for very young kids unless necessary.
6. Treating Underlying Medical Conditions
If bruxism is related to ADHD, ASD, or sensory issues, your dentist may work alongside:
- Paediatricians
- Occupational therapists
- Behavioural specialists
Holistic care ensures better long-term improvement.
Home Care Tips for Parents
To help manage grinding at home:
✔ Avoid chewing gum or hard foods
These can strain jaw muscles.
✔ Use a warm compress on the jaw
Helps relax tight muscles.
✔ Encourage stretching and relaxation
Gentle jaw exercises can help older kids.
✔ Ensure good hydration
Dehydration can worsen bruxism.
✔ Maintain a calm afternoon and evening routine
Reduce overstimulation close to bedtime.
When Should You See a Dentist?
Book a dental appointment if your child:
- Complaints of jaw or tooth pain
- Has visible wear on teeth
- Experiences headaches regularly
- Grinds most nights loudly
- Has difficulty chewing
- Shows signs of sleep disturbance
Early assessment prevents long-term issues.
Most Children Outgrow Teeth Grinding
Many kids naturally stop grinding their teeth as their jaw grows and permanent teeth erupt.
However, monitoring and early intervention help protect their teeth during these crucial developmental years.
