Some children grind their teeth during sleep—a condition called bruxism—which can lead to headaches, jaw pain, and worn-down teeth. A custom-fit mouthguard, worn at night, can help protect your child’s teeth and reduce discomfort. These guards act as a cushion, preventing damage from clenching and grinding. Dentists can assess whether a mouthguard is needed and ensure it fits properly for comfort and effectiveness. Addressing teeth grinding early can prevent long-term dental issues and improve sleep quality. If your child complains of jaw pain or shows signs of tooth wear, talk to your dentist about a nighttime mouthguard.
