You tuck your child in, kiss them goodnight, and then you hear it somewhere around midnight: a low, grinding scrape coming from their room that sounds like nothing a sleeping child should be making. Teeth grinding in kids is more common than most parents realize, and while it can be unsettling to discover, it is usually something that can be addressed with the right guidance.
Dr. J. Rockwell Wright and the team at Kids Dental Center take pride in being the kind of practice where every question gets a real answer. Our pediatric dental services are built around individualized care for every child who walks through the door, and that means getting to the bottom of concerns like this one rather than brushing them off. If your child has been grinding their teeth at night, here is what you need to know.
What Is Teeth Grinding and Why Does It Happen?
Teeth grinding, known clinically as bruxism, refers to the clenching or grinding of the teeth, most often during sleep. According to the American Academy of Pediatrics, teeth grinding is common in toddlers and preschoolers, and while most kids outgrow it, some continue grinding into their teen and adult years.
The reasons children grind their teeth vary widely, and no single cause explains every case. Stress is one of the most well-known contributing factors — school pressures, big life changes, or anxiety about something as simple as an upcoming test can all trigger nighttime grinding. Other common contributors include misaligned teeth, an uneven bite, and certain medications. In some children, grinding is also connected to sleep disturbances, including airway issues that disrupt rest without fully waking the child.
The Link Between Grinding and Your Child’s Airway
One connection that often surprises parents is the relationship between teeth grinding and breathing during sleep. Children who snore, breathe through their mouths, or experience disrupted sleep may grind their teeth as a response to the body’s effort to reopen a partially blocked airway.
When Grinding Is a Sleep Signal
If your child grinds their teeth and also seems tired during the day, struggles to focus, or frequently breathes through their mouth, it may be worth looking beyond the teeth. Addressing the airway can sometimes reduce or resolve grinding entirely. Our airway evaluation and treatment services are designed to identify exactly these kinds of underlying issues and help children breathe and sleep the way they should.
Signs That Grinding May Be Causing Damage
Not all grinding causes lasting harm, but some children grind hard enough and often enough to wear down enamel, cause jaw soreness, or create sensitivity. Here are some signs worth paying attention to:
- Worn, flattened, or chipped tooth surfaces that your dentist notices at a routine cleaning and exam
- Complaints of jaw pain, earaches, or headaches in the morning
- Increased tooth sensitivity to hot or cold temperatures
- Clicking or popping sounds when your child opens or closes their jaw
- Visible indentations on the sides of the tongue from clenching
These signs do not always mean serious damage has occurred, but they are a good reason to bring it up at your child’s next dental visit.
What Can Be Done About It?
The good news is there are real, practical steps to help a child who grinds their teeth. For some kids, the grinding resolves on its own as they grow. For others, a little intervention goes a long way. A custom-fitted nightguard can protect the teeth during sleep, and for children whose grinding is rooted in oral habits or jaw tension, our habit-breaking appliances may offer targeted relief. Reducing stress before bed, establishing a calming bedtime routine, and limiting screen time in the evening can also make a meaningful difference for children whose grinding is tied to anxiety.
