Though grinding is in some cases seen as a result of stress, especially in teens, it is often the result of other factors. In children it is most often the result of increased pressure within the ears. Common causes for increased pressure include allergies and the common cold. In these cases such as these grinding can relieve pressure.

More often than not, children who grind their teeth will naturally outgrow the habit. In some cases a night guard may be recommend, but this is usually for more severe cases only.
