Teeth grinding is harmful for several reasons. First, it causes damage to the teeth by wearing the enamel off the biting surface of the tooth and along the gumline. This can lead to tooth sensitivity. Second, the forces generated from grinding can cause cracks to form in the teeth and can cause the teeth to break.
Specific tips to help a child stop grinding his or her teeth include: 1  Decrease your child's stress, especially just before bed. 2  Try massage and stretching exercises to relax the muscles. 3  Make sure your child's diet includes plenty of water.  Ask your dentist to monitor your child's teeth if he or she is a grinder.
