My 2-Year-Old Grinds Their Teeth at Night. Should I Be Worried?

We get asked about this a lot, and it’s more common than you think. Most nighttime teeth grinding in toddlers goes away as children grow. And usually it’s nothing to worry about. Most parents hear their child grinding and are sure something terrible is happening. So, it’s natural to wonder if you should schedule an emergency appointment. Take a breath. This is one of those parenting moments where your instincts are telling you something might be wrong, but the reality is much less alarming than you think.

If you’ve recently noticed your toddler grinding their teeth while sleeping, you’re not alone. Many new parents book appointments with us specifically to ask about this issue.

Why Does My Toddler Grind Their Teeth at Night?

Teeth grinding in toddlers, called bruxism, is common and usually not cause for concern. Most cases begin around ages 3–4 and relate to normal jaw growth, tooth eruption, and changing bite alignment. Stress, separation anxiety, and sleep disruptions can also trigger nighttime grinding in young children. Most toddlers grow out of it on their own. Mention it at your child’s next dental visit so we can check for any wear on the teeth.

Is It Harmful?

In most cases, teeth grinding in toddlers causes no lasting damage. Baby teeth are temporary, and the grinding typically stops before it causes significant wear. However, pediatric dentists look out for specific warning signs during regular checkups.

We look for excessive wear on the tooth surfaces, complaints of jaw pain or headaches (which toddlers might not articulate clearly), and any changes to how the teeth fit together. A survey by the American Dental Association found that dentists have observed increased teeth grinding across all age groups in recent years, though the causes and outcomes vary between adults and children. Most parents who bring this up either noticed the grinding because they co-sleep or became aware of it on vacation while sharing a hotel room.

When to Schedule a Visit

You should reach out if the grinding becomes louder or more frequent over time. Most toddler grinding is quiet and infrequent, but if it’s happening every night and you can hear it clearly from another room, mention it at your next appointment.

Also, call if your child complains of jaw soreness or has trouble chewing. While toddlers may not say this in those exact words, watch for signs like favoring one side of their mouth or refusing certain foods they normally like.

By the time permanent teeth start coming in, we expect any grinding habits to be resolved, and if they haven’t, we will certainly take a closer look.

What We Look for During Appointments

During regular checkups, we examine the wear patterns on your child’s teeth, check jaw alignment and bite, ask about any pain or discomfort symptoms, and assess whether the grinding has affected dental development. Most often, we’ll tell you to simply monitor the situation and return for your next scheduled visit. We’re looking at the bigger picture of your child’s dental development, not just isolated incidents of grinding.

Nighttime teeth grinding in toddlers usually isn’t cause for alarm. It’s one of those common childhood phases that tends to resolve on its own. That said, your parental instinct to check on these things is valuable, and we’re always here to provide reassurance or treatment when needed.
