What could be causing your 4-year-old child to grind her teeth when she sleeps?
TRY Google–type in “bruxism”. That’s the technical term for teeth grinding. Many times it’s caused by “reflex chewing activity”. Check out info on bruxism. If it continues when she has her permenant teeth, there are mouth guards available (also called bite guards). Many people grind their teeth, sometimes to the point that they wear them down flat! Best to You!
