Teeth grinding in sleep (bruxism) is a common concern among parents, especially in children aged 3 to 10 years. If you’ve ever heard that disturbing “grating” sound at night, you’re not alone nearly 30% of children experience teeth bruxism at some stage. 

Hello! I am Dr. Balachandra. Let’s explore the causes of teeth grinding (bruxism) in children and the appropriate ways to address this condition.

What is Bruxism?     

Bruxism refers to teeth grinding or teeth biting in sleep, often occurring during deep sleep. Most children are unaware of it, and in many cases, it resolves naturally as they grow. 

Important: Teeth grinding is NOT caused by intestinal worms—this is a common myth. 

Why Do Children Grind Their Teeth? 

Understanding the root cause helps in choosing the right bruxism treatment. 

1. Jaw Growth & Tooth Development 

As children transition from baby teeth to permanent teeth, their bite may feel uneven, leading to involuntary grinding. 

2. Ear Pain or Teething Discomfort 

Children may grind to relieve pressure from earaches or erupting teeth. 

3. Breathing Issues 

Kids with mouth breathing, snoring, allergies, or enlarged adenoids are more prone to grinding. 

4. Stress or Emotional Triggers 

Even small changes—school pressure, new routines—can lead to teeth bruxism at night. 

5. Dental Alignment Issues 

Improper bite alignment may require evaluation by a pediatric dental specialist. 

 What NOT to Do 

• Don’t panic – Most cases don’t cause permanent damage
• Don’t scold your child – They are unaware of the habit
• Don’t ignore pain – Jaw pain or headaches need attention 

 What TO Do (Practical Remedies) 

Check for Underlying Causes 

Look for signs like ear pain, blocked nose, or discomfort. 

Improve Breathing 

Treat allergies or nasal congestion to reduce teeth grinding in sleep. 

Manage Stress 

Talk to your child about their day—emotional relief reduces night-time clenching. 

Dental Check-Up 

A dentist can assess if a dental splint for bruxism or alignment correction is needed. 

 Effective Teeth Grinding Remedies (Bedtime Routine) 

 The "Power Down"Hour 

Avoid screens at least 1 hour before bed—blue light overstimulates the brain. 

Relaxation Routine 

Reading, storytelling, or a warm bath helps calm jaw muscles. 

Talk It Out 

Let your child share their thoughts—this reduces stress-related teeth biting in sleep. 

Hydration 

Ensure proper water intake; dehydration can trigger muscle activity. 

When Do You Need Treatment? 

If symptoms persist, a dentist may recommend: 

• Bruxism mouthguard (night guard)
• Bite correction therapies
• Addressing airway or allergy issues 

 Choosing the best night guard for teeth grinding depends on your child’s age and dental condition—always consult a specialist. 

 Mind Ticklers (For Parents) 

• Does your child grind more during a cold or blocked nose?
• Do they wake up tired despite full sleep?
• Is grinding worse on stressful days? 

 Final Thoughts:

Bruxism in children is usually a phase, not a problem. With the right observation, simple lifestyle changes, and timely dental care, you can manage it effectively.
