Hearing your child grind their teeth at night is one of those sounds that immediately puts a parent on edge. It is grating, it feels wrong, and the first thought most parents have is that something must be seriously wrong with their child’s teeth. The reality is that teeth grinding in children is one of the most common habits dentists see, and in many cases it is a normal part of how children develop. That said, knowing when it is something to watch and when it needs attention makes a real difference for your child’s long term dental health.
At Green Acres Family Dentistry, Dr. J. Scott Lyman and his team work regularly with parents who come in concerned about their child’s nighttime grinding. Dr. Lyman takes the time to assess exactly what is happening with the teeth and jaw before making any recommendation, because the right response depends entirely on the child’s age, the severity, and what is causing it.
What Is Teeth Grinding in Children?
Teeth grinding in children is known medically as bruxism. It happens when a child unconsciously clenches their jaw and moves their upper and lower teeth against each other, usually during sleep. Most parents only find out it is happening because they hear the sound from the hallway or notice their child waking up with a sore jaw or headaches.
It is more common than most people realize. Research from the American Academy of Pediatric Dentistry suggests that up to 30 percent of children experience bruxism at some point during childhood, with the highest rates appearing between ages three and seven. Many children grow out of it completely by the time their permanent teeth come in and their bite settles into a stable position.
What Causes Children to Grind Their Teeth in Sleep?
Understanding causes of teeth grinding in children helps parents figure out whether there is something they can address at home or whether a dental visit is the right next step.
The most common cause in younger children is simply development. As baby teeth come in and later fall out, the bite is constantly shifting. The jaw is adjusting to new positions, and grinding is one way the body works through that process. This type of grinding tends to reduce or disappear on its own without any treatment.
Stress and anxiety play a significant role as well, even in young children. A new sibling, a change in school, trouble sleeping, or anything that disrupts a child’s normal sense of security can show up as nighttime grinding. Children process emotional tension differently from adults, and the jaw is one place that tension lands.
Sleep disorders, particularly sleep apnea and disrupted breathing during sleep, are closely linked to bruxism in children. If your child snores, breathes through their mouth at night, or wakes up frequently, it is worth mentioning this alongside the grinding when you speak to a dentist or pediatrician. The two issues often go together.
Some medications, particularly stimulants used to manage ADHD, can also contribute to grinding as a side effect. If your child started grinding around the same time a medication was introduced, that connection is worth raising with their doctor.
When Should You Be Concerned?
Occasional grinding is generally not a cause for alarm, especially in children under seven who still have their baby teeth. Baby tooth enamel is thinner than adult enamel, but the teeth are also temporary. The concern shifts when grinding is persistent, nightly, and starting to leave visible wear on the teeth.
Signs that warrant a dental visit include teeth that are starting to look flattened or shorter than they should, your child complaining of jaw soreness or headaches in the morning, sensitivity in the teeth that was not there before, or grinding that continues after the permanent teeth have come in. Once adult teeth are involved, consistent grinding can cause real damage to the enamel that does not repair itself.
How to Stop Teeth Grinding in Children at Home
There are practical steps parents can take before reaching for a clinical solution. A consistent and calm bedtime routine makes a meaningful difference for many children. Turning screens off at least an hour before bed, keeping the routine predictable, and winding down with something quiet like reading or calm music helps reduce the tension that feeds nighttime grinding.
Hydration matters more than most parents expect. Children who are mildly dehydrated tend to grind more because lower saliva production increases the amount of time teeth are in contact. Making sure your child drinks enough water throughout the day is a simple place to start.
Limiting sugar and caffeine in the hours before bedtime reduces stimulation that can disrupt sleep quality and increase grinding. Even fruit juices consumed close to bedtime can be a factor worth adjusting.
What a Dentist Can Do
Our pediatric dentist in Twin Falls evaluates the teeth for signs of wear, checks the bite alignment, and helps determine whether the grinding is developmental or something that needs to be monitored more closely. For older children whose permanent teeth are grinding consistently, a custom night guard can be made to protect the enamel during sleep. Our dentist in Twin Falls will also check whether airway or bite issues are contributing so that nothing gets overlooked.
Families from Twin Falls and nearby communities like Kimberly and Jerome regularly bring their children in for exactly this kind of evaluation. It is a straightforward visit that gives parents a clear picture of what is actually happening rather than spending months worrying about what they are hearing at night.
Most Children Do Grow Out of It
The reassurance most parents need is this: the majority of children who grind their teeth during their early years stop on their own without any intervention. The transition from baby teeth to permanent teeth naturally resolves many of the bite irregularities that drive the habit. What matters is keeping an eye on the teeth for signs of damage and getting a professional assessment if the grinding is heavy, nightly, or continuing past the point where it should have faded.
Dr. Lyman and the team at Green Acres Family Dentistry are proudly serving families across Twin Falls and the surrounding areas. If your child’s grinding is keeping you up at night or you have noticed changes in their teeth, bring them in for a check. A quick look at the teeth is all it takes to know whether you need to act or simply keep watching.
FAQs
Is it normal for children to grind their teeth at night?
Yes, it is very common. Up to 30 percent of children grind their teeth at some point during childhood, most frequently between ages three and seven. Most outgrow it without any treatment as their permanent teeth come in and their bite stabilizes.
What are the main causes of teeth grinding in children?
The most common causes include normal dental development, stress or anxiety, disrupted sleep or breathing issues like sleep apnea, and in some cases medications used to treat ADHD. Identifying the likely cause helps determine the right response.
How do I stop my child from grinding their teeth in sleep?
Start with a calm and consistent bedtime routine, limit screens before bed, ensure good hydration throughout the day, and reduce sugar close to bedtime. If grinding continues or worsens, a dental evaluation is the next step.
At what age should I take my child to the dentist for teeth grinding?
If your child is under seven and has no symptoms beyond the sound, a mention at their next regular checkup is usually enough. If you notice worn or flattened teeth, morning jaw soreness, headaches, or grinding that continues after permanent teeth have come in, schedule a visit sooner rather than waiting.
