Teeth grinding, or bruxism, refers to excessive grinding of the teeth and/or excessive clenching of the jaw, and is common in children. This can occur during the day or night. The first indication is the noise created by your child grinding on their teeth during sleep. Or, you may notice wear (teeth getting shorter) to your child’s dentition. Although teeth grinding is often the result of stress in adults, the same is not always true with children.
There are a range of psychological, physiological, and physical factors which can be the reason behind bruxism in children.
