Parents are frequently concerned about the noise they hear their kids’ teeth making at night. There are several theories surrounding why kids often grind their teeth at night. The two most common are; stress due to changes in the environment (home, school, etc.) and pressure in the inner ears at night. Either way, most kids with teeth-grinding issues do not need dental treatment. If there is evidence of excessive wear on your child’s teeth, your dentist may recommend a night guard. Most children will outgrow this condition between the ages of 9-12, and it will decrease over time as they reach the 6-9 age range.
