Hearing your child grind their teeth in their sleep can be alarming. That harsh, crunching sound, known medically as pediatric bruxism, often leaves parents lying awake, wondering if something is wrong. Should you be concerned, or is this just a passing phase? When you consult a dentist in NE Calgary, you will quickly learn that night grinding in children is surprisingly common. However, understanding why it happens and when intervention is needed will help protect your child’s growing smile.
Understanding Pediatric Bruxism
Teeth grinding (bruxism) is when someone clenches or grinds their teeth without meaning to. In children, it usually occurs in deep sleep cycles. Studies suggest that as many as two out of three children grind their teeth at night at some time in their early years.
For many toddlers and young children, bruxism is temporary and harmless. Most kids outgrow the habit on their own by the time their permanent teeth fully emerge.
Why Kids Grind Their Teeth at Night
Children grind their teeth for many reasons, from normal growth to temporary stress:
- Teething & Dental Growth: Infants and toddlers often grind to soothe sore gums when new teeth break through.
- Misaligned Teeth: If top and bottom teeth do not fit together smoothly, kids may grind to find a comfortable bite.
- Stress & Anxiety: New routines, school stress, or worry can show up as nighttime jaw clenching.
- Airway or Breathing Issues: Swollen tonsils or mouth breathing can force kids to shift their jaw at night to breathe easier, leading to grinding.
- Earaches or Pain: Kids sometimes grind their jaw to relieve pressure or ache in their ears.
Is Night Grinding Normal for Children?
In most cases, yes. Mild grinding rarely causes permanent damage to baby teeth, which naturally fall out anyway. It only becomes a concern if grinding continues after adult teeth come in or starts causing pain and noticeable wear.
Signs Your Child May Need Professional Help
While many children outgrow the habit naturally, parents should stay alert for warning signs. You should schedule a visit with a dentist near you if you notice any of the following symptoms:
- Visible wear, chips, or flattened edges on primary or permanent teeth.
- Complaints of a sore jaw, facial pain, or earaches upon waking.
- Sensitivity to hot, cold, or sweet foods due to worn-down enamel.
- Tension headaches, particularly around the temples in the morning.
- Loud grinding sounds occur consistently every single night.
- Disrupted sleep patterns or frequent daytime fatigue.
When Do Kids Need a Night Guard?
A custom mouthguard is one of the most effective ways to protect teeth from heavy grinding, but it is not always recommended for younger kids. Because a young child’s jaw is rapidly growing, rigid night guards can interfere with normal bone development.
A dental professional will generally consider a Kids Night Guard in NE Calgary under specific circumstances:
- Permanent Teeth are Present: Once permanent adult teeth begin erupting (usually around age six or seven), protecting the adult enamel becomes a top priority.
- Severe Tooth Wear: When grinding is so forceful that the protective enamel is worn away, exposing the softer dentin underneath.
- Chronic Jaw Pain: If your child has frequent pain in the temporomandibular joint (TMJ) or muscular tension.
Your practitioner will evaluate your child’s jaw growth, tooth development, and symptoms before deciding if a mouthguard is the right solution.
How Parents Can Help at Home
Along with professional dental care, simple changes at home can lower nighttime stress and reduce grinding habits:
- Create a quiet, screen-free evening ritual to help relieve nighttime anxiety.
- Before sleeping, take a warm bath or give your jaw a light massage to relax facial muscles.
- Ensure your toddler drinks enough fluids throughout the day.
- Encourage open conversations about any worries or stresses your child might be facing.

Frequently Asked Questions
When do most children stop grinding their teeth?
Most kids outgrow grinding when their adult teeth and jaws settle in, between ages 9 and 12. If you keep grinding past 12, see your dentist to save your enamel.
Can over-the-counter night guards be used for young children?
No. Store-bought guards can restrict healthy jaw growth and throw off your child’s bite. Any guard used during childhood must be custom-made and monitored by a dentist.
Does teeth grinding mean my child has intestinal worms?
No. That is an old myth. Grinding is usually caused by jaw growth, stress, bite alignment, or airway issues; not parasites.
Can swollen tonsils or airway issues cause grinding?
Yes. When enlarged tonsils or adenoids make breathing difficult at night, kids subconsciously shift their jaw forward to open their airway, which can cause them to grind.
Will grinding permanently damage my child’s baby teeth?
Usually no, as baby teeth are temporary. However, excessive grinding can wear through the enamel to the sensitive inner layer, increasing the risk of toothaches or decay.
