Bruxism, the clinical term for teeth grinding, shows up quite often in young children. Research suggests that roughly 30 percent of kids grind their teeth before they turn five years old. In most cases, the habit fades on its own by around age six and does not signal a deeper problem.
That said, grinding does not always resolve on its own. When a child older than six continues to wake with a sore jaw, or siblings and friends at sleepovers mention hearing grinding or gnashing sounds overnight, bruxism may still be present.
Parents who notice frequent grinding often want to understand what might be driving it. Scheduling a visit with a dentist is typically the best way to pinpoint the cause and determine what, if anything, needs to be done.
Factors Related to Development
Several developmental changes can play a role in why children grind their teeth. In younger kids, the teething process is often a factor, since new teeth pushing through the gums can create discomfort, and grinding can become a way for a child to ease that pressure.
As a child’s jaw and teeth continue to grow, misalignment or other orthodontic concerns can also develop, and these shifts can contribute to grinding as well.
Stress and Emotional Triggers
Just as it does in adults, bruxism in kids can stem from stress or anxiety. Starting at a new school, changes within the family, pressure to perform academically, or friction with peers are all situations that can raise a child’s stress levels and, in turn, lead to grinding.
In many cases, this happens without the child even realizing it, functioning as an unconscious outlet for releasing tension and processing emotional stress.
Factors Linked to Sleep
At any age, grinding tends to happen most during sleep. Factors like sleep apnea, chronic snoring, or other breathing difficulties can contribute to bruxism in kids, since an obstructed airway or disordered breathing can trigger jaw movement and grinding as the body instinctively tries to reopen the airway.
Bite and Dental Alignment Issues
Kids who have dental issues, including malocclusion (a misaligned bite), crowded or missing teeth, or temporomandibular joint (TMJ) issues, may be more likely to grind. These conditions can leave the jaw feeling unstable or uncomfortable, and the body may respond by shifting into a more comfortable position for the teeth and jaw, which can show up as grinding.
Habits and Behaviors That Contribute to Grinding
Habits such as thumb-sucking, tongue thrusting, or nail-biting can also lead children toward clenching or grinding. Repeated over time, these behaviors can shift the position of the teeth and contribute to bruxism. Parents should also keep in mind that chewing on objects or relying heavily on a pacifier can play a role in a child’s tendency to grind.
