Nocturnal or diurnal bruxism, commonly manifested as teeth grinding, is a frequent occurrence in early childhood. The involuntary clenching and grinding of teeth, particularly during sleep, constitutes this parafunctional activity.
Understanding the etiology of teeth grinding in young children is important for parental awareness and potential intervention. While the exact cause can be multifactorial, common contributing factors include misaligned teeth, stress or anxiety, and even certain medical conditions. In some cases, bruxism may be a response to ear pain or teething discomfort.
