While teeth grinding in young children may not sound like the healthiest of noises, there is generally nothing to worry about. Teeth grinding, also known as bruxism, is very common. Most young children will grow out of this habit once their permanent teeth start to come in. Once a child’s permanent molars come in, the permanent bite is established. Before this, a child’s bite is constantly changing. No treatment is recommended for young children as it would interfere with their teeth’s normal growth and development. If you notice that your child is grinding his or her teeth, inform Dr. Kane. She will track wear patterns and will recommend treatment, when appropriate.
