What Is Bruxism?
Bruxism is the unconscious clenching or grinding of teeth. In children, it usually occurs during nighttime sleep but can also happen during the day. Research shows that approximately 15-33% of children experience bruxism.
Bruxism is frequently seen during primary and mixed dentition periods and in most cases naturally decreases when permanent teeth emerge.
Causes of Bruxism in Children
Bruxism doesn't have a single cause; usually multiple factors play a role. The most common causes include stress and anxiety, sleep disorders (snoring, sleep apnea), bite disorders, and teething pain.
Children with ADHD may experience bruxism more frequently. Certain medications can also trigger bruxism.
Symptoms of Bruxism
You may suspect bruxism if your child shows: grinding sounds from teeth during sleep, jaw pain or headache upon waking, tooth wear or flattening, and tooth sensitivity.
Ear pain, facial muscle tension, and disrupted sleep quality can also be indicators. If you notice any of these symptoms, consult your dentist.
Treatment Options
Treatment is shaped by the underlying cause. In mild cases, monitoring is sufficient; most children outgrow bruxism. For stress-related cases, relaxation techniques and sleep hygiene improvements are recommended.
If there is significant tooth wear, a night guard (splint) may be used. If a bite disorder is detected, orthodontic treatment can be planned.
