Does Your Child Grind His or Her Teeth at Night?

Bruxism, or the grinding of teeth, is remarkably common in children and adults.  For some children, this tooth grinding is limited to daytime hours, but nighttime grinding (during sleep) is most prevalent.  Bruxism can lead to a wide range of dental problems, depending on the frequency of the behavior, the intensity of the grinding, and the underlying causes of the grinding.

A wide range of psychological, physiological, and physical factors may lead children to brux.  In particular, jaw misalignment (bad bite), stress, and traumatic brain injury are all thought to contribute to bruxism, although grinding can also occur as a side effect of certain medications.

What are some symptoms of bruxism?

In general, parents can usually hear intense grinding – especially when it occurs at nighttime.  Subtle daytime jaw clenching and grinding, however, can be difficult to pinpoint.  Oftentimes, general symptoms provide clues as to whether or not the child is bruxing, including:

  • Frequent complaints of headache.
  • Injured teeth and gums.
  • Loud grinding or clicking sounds.
  • Rhythmic tightening or clenching of the jaw muscles.
  • Unusual complaints about painful jaw muscles – especially in the morning.
  • Unusual tooth sensitivity to hot and cold foods.

How can bruxism damage my child’s teeth?

Bruxism is characterized by the grinding of the upper jaw against the lower jaw.  Especially in cases where there is vigorous grinding, the child may experience moderate to severe jaw discomfort, headaches, and ear pain.  Even if the child is completely unaware of nighttime bruxing (and parents are unable to hear it), the condition of the teeth provides the pediatric dentist with important clues.

First, chronic grinders usually show an excessive wear pattern on the teeth.  If jaw misalignment is the cause, tooth enamel may be worn down in specific areas.  In addition, children who brux are more susceptible to chipped teeth, facial pain, gum injury, and temperature sensitivity.  In extreme cases, frequent, harsh grinding can lead to the early onset of temporomandibular joint disorder (TMJ).

What causes bruxism?

Bruxism can be caused by several different factors. Most commonly, “bad bite” or jaw misalignment promotes grinding.  Pediatric dentists also notice that children tend to brux more frequently in response to life stressors.  If the child is going through a particularly stressful exam period or is relocating to a new school for example, nighttime bruxing may either begin or intensify.

Children with certain developmental disorders and brain injuries may be at particular risk for grinding.  In such cases, the pediatric dentist may suggest botulism injections to calm the facial muscles, or provide a protective nighttime mouthpiece.  If the onset of bruxing is sudden, current medications need to be evaluated.  Though bruxing is a rare side effect of specific medications, the medication itself may need to be switched for an alternate brand.

How is bruxism treated?

Bruxing spontaneously ceases by the age of thirteen in the majority of children.  In the meantime however, the pediatric dentist will continually monitor its effect on the child’s teeth and may provide an interventional strategy.

In general, the cause of the grinding dictates the treatment approach.  If the child’s teeth are badly misaligned, the pediatric dentist may take steps to correct this.  Some of the available options include: altering the biting surface of teeth with crowns, and beginning occlusal treatment.

If bruxing seems to be exacerbated by stress, the pediatric dentist may recommend relaxation classes, professional therapy, or special exercises.  The child’s pediatrician may also provide muscle relaxants to alleviate jaw clenching and reduce jaw spasms.

In cases where young teeth are sustaining significant damage, the pediatric dentist may suggest a specialized nighttime dental appliance such as a nighttime mouth guard.  Mouth guards stop tooth surfaces from grinding against each other, and look similar to a mouthpiece a person might wear during sports.  Bite splints, or bite plates, fulfill the same function, and are almost universally successful in preventing grinding damage.

"Friendly staff, very clean offices, thorough explanation of services and pro-active maintenance tips, no pain...all you could ask for in a dental team! Thanks"

I came to Hawthorn Woods Family Dentistry, since I had problems with my gums and overall dental health. Dr. Copeland provided a consultation and recommended a long-term treatment plan, which included porcelain veneers and improving my overall dental health in the course of two years. I could not believe the transformation and I enjoyed being part of the process!
Dr. Copeland performed the dentistry for my porcelain veneers, which look natural and help keep my gums healthy. Dr. Copeland gave me the smile I never had, but always wanted and did so in a caring and professional manner.
The staff at Hawthorn Woods Family Dentistry wanted to make sure I was happy and healthy and were accommodating to my schedule by providing appointments that worked for me.
What I like most about Hawthorn Woods Family Dentistry is that the aftercare and preparation were just as important to Dr. Copeland and his staff as the actual dentistry for the final fitting and placement of the veneers.

I went to your office to get a tooth extracted. I wanted to let you know what a wonderful experience I had! Jeffrey Copeland explained everything to me, helped me relax, feel at ease. The best part- I didn’t feel any pain! Never before have I felt more relaxed getting dental work! His assistant, Kristen, was just as comforting.

My sisters, Karen McGuinn and Sue Bowers, are patients of yours and highly recommended I come to you. The best advice I ever received from them!

I can’t say enough about Dr. Copeland. I’m going to recommend everyone I know to your practice!
