As a pediatric dentist who’s been caring for children’s smiles for over three decades, I’ve seen it all. Or at least, a lot.
One of the most rewarding parts of my job is helping parents feel confident about their child’s oral health. I often hear the same question in the exam room: “Doctor Howell, when should I start worrying about my child’s grinding?” It’s a common concern in Utah Valley, especially with busy families. Noticing your little one clenching or grinding at night is a sure sign. You may worry and think it means that something’s wrong, or that it’ll lead to bigger problems down the road. Let me put your mind at ease—teeth grinding (also called bruxism) in kids is very common, often harmless, and usually manageable with the right approach.
First, I’ll go over the basic causes, and then I’ll go over signs to look out for and some easy home treatments.
What Causes Teeth Grinding in Children?
From my experience at Orem Pediatric Dentistry, teeth grinding usually starts when kids are young—sometimes as early as toddlerhood—and peaks around ages 3 to 6, though it can continue into the teen years. The most frequent trigger I see is stress or anxiety. These triggers are common in school, with new siblings, changes at home, or even excitement about upcoming events. All of these can cause kids to clench their jaws unconsciously, especially while sleeping. I’ve had parents describe hearing a grinding sound like “little rocks rubbing together” at night, and it can come as a surprise to parents when they discover it.
Other common causes include misaligned teeth (malocclusion), where the bite doesn’t line up perfectly, leading to grinding as the jaw seeks a comfortable position. Earaches or allergies can play a role too—kids might grind to relieve pressure in their ears or sinuses. There are also habits like thumb-sucking or prolonged pacifier use, which can shift teeth and contribute to bruxism. In rare cases, it ties to conditions like sleep apnea, but that’s something we screen for carefully during exams.
One memorable case was little Emma, a 5-year-old from Orem whose mom brought her in worried about worn-down baby teeth. After chatting with Emma (she loved telling me about her soccer games), we discovered she was grinding due to excitement and slight anxiety about starting kindergarten. No major issues—just a common childhood phase. By understanding the root cause, we could address it gently without jumping to big interventions.
If your child grinds, start by observing: Does it happen only at night?
During the day when they’re focused or upset?
The best care results for accurate data. By recording all events (times when problems occur and their duration), we can treat concerns and achieve the best outcomes. So, always make notes of what you see, how long it lasts, and any and all signs or symptoms.
Recognizing the Signs and When It’s Time to Act
Some parents don’t realize their child is grinding until they hear it themselves or notice wear on the teeth. Common signs I’ve pointed out in checkups include flattened tooth surfaces, chipped enamel on baby teeth, jaw soreness in the morning, headaches (especially around the temples), or complaints of ear pain without an actual ear infection. I sometimes suggest that parents look at the inside of the cheeks or check for tongue biting marks from nighttime clenching.
In most kids, mild grinding doesn’t cause lasting damage because baby teeth fall out and are replaced with adult teeth. But if signs are moderate to severe, they can lead to sensitivity, cracked teeth, or even affect jaw development over time. I always tell parents: Early attention prevents bigger issues. During routine visits at our office, I check for wear patterns and ask about sleep habits. If grinding is noticeable, we discuss whether a custom mouth guard might help. Again, a short and routine home exam can help tremendously so I encourage you to get into the habit of doing that every night. It’s better to be safe than sorry as the old saying goes.
Now, daytime grinding is different. It’s often tied to concentration—like when kids are drawing, playing video games, or doing homework. Gentle reminders to relax the jaw can make a difference. And if your child wakes up tired or irritable, it could signal disrupted sleep from grinding. An example of this is when you see a child getting a bit fidgety and fussing around a little more than usual.
Just noticing the signs can help you zero in on what me be going on, which can be confirmed and treated by a doctor.
Effective Ways to Manage and Reduce Teeth Grinding at Home
Over the years, I’ve shared countless tips that any parent can follow to help care for their children’s teeth.
When it comes to issues with grinding teeth, I recommend starting with stress reduction—simple bedtime routines work wonders. Encourage relaxing activities like reading, gentle stretching, or warm baths before bed. Limit screen time an hour before lights out, as blue light can amp up excitement and contribute to clenching. Diet plays a part too. Avoid sugary or caffeinated snacks close to bedtime—they can heighten restlessness. Instead, opt for warm drinks or warm milk. If allergies are a factor, keeping the bedroom dust-free and using a humidifier can ease some of the sinus pressure that can prompt grinding.
For many kids, a soft mouth guard at night is a game-changer. At OPD, we create custom-fitted ones that are comfortable and effective at cushioning the teeth. They’re far better than over-the-counter options, which can be bulky or cause pain due to a poor fit. One dad told me his son’s grinding sounds disappeared within a week of wearing his guard—sleep improved for the whole family!
Behavioral tweaks help too. Praise your child for keeping their teeth apart during the day (“Great job relaxing your mouth!”). For toddlers still using pacifiers, weaning gently can reduce pressure on jaws. And regular dental visits—starting by age 1 or when the first tooth appears—let us monitor progress and catch any alignment issues early. These small steps add up to big protection for your child’s developing smile.
Building a Lifetime of Healthy Habits: My Advice for Parents
As a pediatric dentist who’s watched generations of Utah Valley kids grow up, I believe teeth grinding is often just one chapter in a child’s oral health story—one we can guide positively. The goal isn’t just to stop the grinding, but to foster habits that support strong, confident smiles for life. Encourage brushing twice daily with fluoride toothpaste, flossing, and a balanced diet low in sugar. Celebrate good habits with fun rewards like sticker charts—I’ve seen them motivate even reluctant brushers!
If grinding persists or worsens, don’t hesitate to bring your child in. We offer gentle evaluations in a safe, comfortable environment. Resources like our office tour videos or parent guides can help prepare kids, making visits something to look forward to rather than fear.
Remember my young patient Emma? A few adjustments—consistent bedtime routines, a custom guard for tough nights, and lots of encouragement—helped her grinding ease significantly. Today, she’s a happy middle-schooler with a beautiful smile and no jaw complaints. Stories like hers remind me why I love this work: helping families in Orem navigate these everyday challenges so kids can focus on being kids.

Schedule a visit at Orem Pediatric Dentistry, and let’s work together to keep your little one’s smile bright and healthy.
