What causes teeth grinding in toddlers while sleeping?
Common reasons for teeth grinding are stress, frustration,
anxiety. It could also be as a results of abnormal occlusion (the
way the upper and lower teeth fit together), or crooked or missing
teeth. This phenomenon is known as "Bruxism". There are different
ways to treat this. For more information search for "Bruxism" on
Answers.com (link on the right).
Tgdan: Teeth grinding (bruxism) in children is very
common (espescially when they have new teeth coming through) and is
not usually something to worry about as it will probably go away on
its own. If your child is still grinding their teeth when their
adult teeth have come through then it may be time to consider a
nightguard to protect their teeth. In the mean time though you
should stop worrying!
