If your child has been complaining of a sore jaw in the morning or you have heard a soft grinding noise when you walked by their room at night, your child may be suffering from bruxism.
Bruxism -- or teeth grinding -- generally develops in children around four or five years of age and usually goes away on its own by age 10. It has been estimated that up to 30 percent of children develop bruxism at some point.
In addition to teeth grinding, other symptoms of bruxism include increased tooth sensitivity, tightness of jaw muscles, earaches, dull morning headaches, facial pain and signs of chewed tissue on the inside of your child's cheek. Unfortunately, the causes of bruxism are not completely understood. Some experts think that teeth grinding is caused by stress, but others believe it is linked to tooth pain or misalignment, such as an overbite.
Since most cases of childhood bruxism resolve on their own before kids lose their baby teeth, there is little risk of permanent damage. Very often, mild headaches and jaw pain will be the only negative effects your child experiences and you may never realize what caused them before bruxism ceases.
