Bruxism, or teeth grinding, is a common condition that affects both adults and children. It is the habitual grinding or clenching of teeth, often during sleep, and can cause a variety of oral health issues if left untreated. As a parent, it’s important to be aware of the signs of teeth-grinding children and take appropriate action to prevent further damage.

In this blog, our pediatric dentistry in Lowell will discuss what bruxism means, its causes, symptoms, how to determine if your child is teeth grinding, steps parents can take to avoid bruxism, and when it’s time to consult a dental professional.

What is Bruxism?

Bruxism is a condition characterized by the grinding or clenching of teeth, typically during sleep, although it can also occur during waking hours. Children may develop bruxism for various reasons, including stress, anxiety, misaligned teeth, and abnormal bite. The exact cause of bruxism in children is not always clear, but it is believed to be related to a combination of physical, psychological, and genetic factors.

Symptoms of Bruxism in Children

Bruxism can have several telltale signs in children. Some common symptoms of bruxism include:

  • Grinding or clenching sounds during sleepteeth grinding children
  • Complaints of jaw pain, headache, or earache
  • Worn, flattened, or chipped teeth
  • Increased tooth sensitivity
  • Irritated or swollen gums
  • Disrupted sleep patterns
  • Changes in bite or alignment of teeth

If you notice any of these symptoms in your child, it may be an indication that they are grinding their teeth and may have bruxism.

Causes of Bruxism in Children

There are a variety of ways that bruxism may develop in kids. Getting a comprehensive consultation is the best way to determine and deal with it. Nevertheless, here are some of the possible causes of bruxism or teeth-grinding children:

Dental Issues

Dental problems such as misaligned teeth, an abnormal bite, or missing teeth can cause bruxism in children. When the teeth do not fit together properly, it can lead to grinding or clenching of the teeth as the child’s body tries to find a comfortable position for the jaw.

Stress and Anxiety

Just like adults, children can also experience stress and anxiety, which may manifest as teeth grinding. Stressors such as school pressure, family issues, or changes in routine can trigger bruxism in kids. Children may grind their teeth as a way to cope with stress or express their anxiety.

Sleep Disorders

Sleep disorders, such as sleep apnea or restless leg syndrome, can also be a cause of bruxism in children. These conditions disrupt the quality of sleep, leading to involuntary teeth grinding or clenching during sleep.

Hyperactivity or Aggressive Behavior

Children who are hyperactive or exhibit aggressive behavior may also be more prone to bruxism. The excess energy or aggression may manifest as teeth grinding or clenching during wakeful moments or during sleep.


Certain medications, such as those used to treat attention deficit hyperactivity disorder (ADHD), can increase the risk of bruxism in children. These medications may affect the nervous system and result in involuntary teeth grinding or clenching.

Genetic Factors

Bruxism can sometimes have a genetic component, with children having a higher risk of developing the condition if their parents or siblings also grind their teeth.

Habits and Mouth Breathing

Habits such as thumb sucking, tongue thrusting, or prolonged pacifier use, as well as habitual mouth breathing, can cause an imbalance in the oral muscles and lead to bruxism in children.

Nutritional Factors

Poor nutrition, including vitamin and mineral deficiencies, can affect the development of teeth and jaw muscles, potentially leading to bruxism in children.

How to Determine If Your Child Has Bruxism


Detecting bruxism in children can be challenging, as it often occurs during sleep. However, there are some signs that parents can look out for. One common sign is the presence of grinding or clenching sounds during sleep.

You may also notice that your child complains of jaw pain, headache, or earache upon waking up. Regular dental check-ups may also reveal signs of bruxism, such as worn, flattened, or chipped teeth, increased tooth sensitivity, and changes in bite or alignment of teeth.

Steps Parents Can Take to Avoid Teeth Grinding Children

As a parent, there are several proactive steps you can take to help prevent or reduce the occurrence of bruxism in your child:

Create a Relaxing Bedtime Routine

Establish a calming bedtime routine for your child, such as reading a book, listening to soft music, or engaging in relaxing activities to help reduce stress and anxiety.

Manage Stress and Anxiety

If your child is experiencing stress or anxiety, try to identify and address the underlying causes. Encourage open communication with your child and offer support and reassurance.

Promote Good Oral Health

Ensure that your child maintains good oral hygiene habits, including regular brushing and flossing, to keep their teeth and gums healthy. This can help prevent potential triggers for bruxism, such as gum irritation or dental problems.

Limit Consumption of Stimulants

Avoid giving your child food or drinks that contain caffeine, such as chocolate or soda, as stimulants can exacerbate bruxism.

Use a Nightguard

A nightguard is a custom-fitted dental appliance that can be worn during sleep to protect the teeth from grinding and clenching. Talk to your child’s dentist about whether a nightguard may be appropriate for your child.

When to Consult a Dental Professional

If you suspect that your child is grinding their teeth or exhibiting symptoms of bruxism, it’s important to consult a dental professional for a proper diagnosis and appropriate treatment options. A pediatric dentist can assess your child’s oral health, identify the underlying causes of bruxism, and provide tailored recommendations to manage the condition effectively.
