Why Does My Child Grind His or Her Teeth?

Why Does My Child Grind His or Her Teeth?

Ever hear a sound like a wild animal gnashing its teeth coming from your child’s bedroom in the middle of the night?


No worries.  Turns out lots of our kids are those wild animals.


While teeth grinding may not sound like the healthiest of noises to come out of your child’s mouth, there’s generally little to worry about, according to the American Academy of Pediatric Dentistry.


Six common questions asked…

 1.  Why do kids grind their teeth?  Does the answer change depending on the age of the child?


Children exhibit teeth grinding very commonly.  We often see it in children younger than 7-8 years old.  A lot of children will stop grinding once their six-year permanent molars erupt.  Their “permanent teeth bite” begins to establish itself once those molars erupt.


Prior to this, children’s bites are very flexible and subject to changes as they grow.  Occasionally, children will exhibit an abnormal bite causing them to grind because of the placement of their teeth.

 2.  Could it be stress-related?  Do children grind their teeth for some of the same reasons adults might grind their teeth?


Stress-related grinding is more common in students of middle school and high school age groups when (final exams and other) major testing occurs. 

3.  What should parents do if their child is grinding his or her teeth?


If the child is still very young with baby teeth still present, nothing needs to be done as we do not want to affect their growth.  If the child is older, intervention may be necessary.   The plan is to protect the permanent teeth while not negatively affecting their normal growth.

4. What should parents look out for?  When should they worry?


The children’s dentist should notice and track wear patterns and recommend treatment when appropriate.

5. How common is teeth-grinding?


It is very common in children less than 7 years of age.  There are adults that do this also, so not all children outgrow grinding.  According to some studies, there is also a correlation between children grinding their teeth and those children that have sleeping disorders.

6.  Any other tips for parents who are concerned about their children’s teeth-grinding issue?


Our major concern is that permanent teeth are not affected and normal growth is allowed to occur.  Many children do this and it does not mean that they are stressed, rather sometimes this is a natural expression of frustration until their vocabulary increases and they can verbally express their frustrations.  In most cases this is a subconscious response and will change with age and growth.
