Hearing your toddler grinding their teeth at night can be unsettling. This habit, known as sleep bruxism, is common during early childhood and often improves as children grow. However, persistent grinding may contribute to oral health concerns.

Why Do Toddlers Grind Their Teeth?
Several factors may contribute to teeth grinding during sleep, and in many cases, more than one cause may be involved.
Developing Baby Teeth and Bite Changes
As primary teeth erupt, the upper and lower teeth gradually move into position. Toddlers may briefly grind their teeth as they adjust to these changes and learn how their teeth fit together.
Mouth Breathing and Airway Concerns
Children who regularly breathe through their mouths during sleep because of allergies, nasal congestion, or enlarged tonsils may be more likely to experience sleep bruxism. Interrupted breathing during sleep may increase jaw muscle activity, which can contribute to teeth grinding.
Stress or Changes in Routine
Changes to a child’s daily routine, such as starting daycare, traveling, moving, or experiencing exciting or stressful events, may temporarily contribute to teeth grinding. While the exact relationship is not fully understood, emotional or physical stress may increase muscle activity during sleep, making sleep bruxism more noticeable in some children.
How to Stop Toddler From Grinding Teeth
Depending on the cause, a few simple measures may help reduce nighttime teeth grinding or identify underlying concerns that may require attention. These include:
- Maintain a consistent bedtime routine: A regular bedtime, calming activities, and limiting screen time before bed may promote better sleep for some children.
- Address mouth breathing: If your child frequently breathes through their mouth, snores, or sleeps with their mouth open, mention these symptoms during their dental or medical visit so the underlying cause can be evaluated.
- Schedule regular dental visits: Routine dental exams allow your pediatric dentist to monitor your child’s teeth, bite, and jaw development and identify signs of excessive grinding or tooth wear early.
If treatment is needed, recommendations depend on the amount of tooth wear, your child’s symptoms, and their stage of dental development.
When Is It Time to Seek Care?
Although occasional teeth grinding is common, persistent grinding or any of the following signs should be evaluated:
- Jaw soreness after waking
- Chipped teeth
- Tooth sensitivity
- Difficulty chewing
- Frequent headaches
- Loud nighttime grinding that continues for several months
Regular dental exams help identify excessive tooth wear and other concerns early, allowing them to be monitored before more significant problems develop.

FAQs
At what age do most children stop grinding their teeth?
Many children outgrow teeth grinding as their jaws and bite continue to develop. The timing varies, and some children may continue grinding into their school-age years.
Can certain foods or drinks cause teeth grinding?
No specific foods have been shown to cause sleep bruxism. However, maintaining healthy sleep habits and limiting caffeine-containing foods or beverages can support better sleep.
Can teeth grinding damage baby teeth?
Occasional teeth grinding usually does not cause lasting damage, but frequent or forceful grinding can wear down tooth enamel, chip teeth, contribute to tooth sensitivity and jaw pain, and irritate the temporomandibular joint (TMJ).
