It is not known for certain why some childrenstart grinding their teeth and some children don't. There are many theories tosuggest that it could be down to the fact that the sets of top and bottom teethdo not fit together comfortably due to the fact that children's teeth and jawsgrow in phases leading to unpleasant sensations in the area. The naturalresponse of the child is to grind their teeth to soothe themselves which oftenlater develops into a habit. It has also been shown that both children andadults grind their teeth when they feel anxious in some way, or even as aresponse to facial pain such as an earache or teething. It has also been shownthat hyperactive children have developed bruxism.
More recent research has suggested that sleep disturbances may be a cause forbruxism in children as well as causing a number of other problems such asbed-wetting, drooling and sleep-talking. Interruptions in the rapid eye movement(REM) patterns due to dehydration during sleep can be the underlying cause ofmany of these problems, though your dentist will be able to advise you more onthis matter.
