Children grinding teeth is quite common
On an estimated average, for every ten children under five, three of them will likely to have experience nighttime bruxism. Bruxism is a term to describe grinding of the teeth. Children grinding teeth is quite common, and quite often resolves on its own. Some believe it happens because the top and bottom teeth are out of alignment. In other cases a child may grind their teeth in response to an ear infection or toothache. Stress at school or home can also cause jaw clenching and teeth grinding in children, so this should be minimized as much as possible.
