Is it normal for babies to grind their teeth?

Why This Happens

Babies may grind their teeth for a variety of developmental and sensory reasons. Since infants cannot communicate their discomfort with words, these habits often serve as a form of self-soothing.

• Teething discomfort: As new teeth break through the gums, the pressure and irritation can lead a baby to rub their teeth together or grind them to alleviate the ache.
• Developmental exploration: Babies are naturally curious about their bodies. Grinding teeth may simply be a way for them to explore the sensation of their new teeth meeting.
• Jaw alignment: As a child’s jaw grows and teeth emerge, they may grind their teeth to “find” a comfortable resting position for their bite.
• Stress or overstimulation: While less common in very young infants, toddlers may grind their teeth as a response to a hectic day or a change in routine.

What It Might Mean in Your Situation

Whether this behavior is a passing phase or something requiring attention usually depends on the pattern and accompanying symptoms. Consider the timing: does it happen mostly during naps, while they are waking up, or during a known teething window?

If the grinding is occasional and the baby seems happy and healthy, it is likely a temporary habit. However, if you notice the baby is consistently irritable, avoiding food, or if you see visible wear on the enamel of the baby teeth, the meaning shifts from “exploration” to a potential need for professional guidance. The consistency of the habit and how it affects their sleep quality are the primary factors to observe.

What To Do About It

1. Offer soothing alternatives: If the grinding is related to teething, provide a chilled (not frozen) teething ring or a clean, damp washcloth for them to chew on. This redirects the urge to grind.
2. Create a calming bedtime routine: Since bruxism often happens during sleep, a warm bath, a gentle massage, or a consistent story-time routine can help relax the baby’s jaw and muscles before they drift off.
3. Monitor and document: Keep a brief log of when the grinding occurs. Note if it happens during specific times of the day or coincided with a new tooth emerging. This data is incredibly helpful for your pediatrician.

Real-Life Example

Imagine a ten-month-old baby who has recently started cutting their upper incisors. The parents notice the baby making a clicking or grinding sound with their teeth every time they are settling down for a nap. Instead of worrying, the parents offer a cold silicone teether and spend a few extra minutes rocking the baby to ensure they are fully relaxed. Over the next two weeks, as the teeth fully emerge, the grinding frequency decreases and eventually stops.

When To Seek Outside Help

While baby bruxism is often harmless, outside help from a pediatrician or a pediatric dentist is recommended if the grinding is severe enough to cause tooth wear, if the child complains of jaw pain, or if the habit is accompanied by significant sleep apnea symptoms (like snoring or gasping). If the behavior is causing you persistent distress or anxiety, consulting a healthcare professional can provide the necessary reassurance and a personalized plan for your child.
