If your child accidentally knocked out one of their permanent teeth, gently clean out the area with a little bit of warm salt water and put something cold like a bag of peas or ice wrapped in a towel on the outside of the injured area. If any portion of the tooth has been knocked out save those fragments by placing them in milk and reach out to our office for an emergency dental visit. The sooner you can get in, the better the chances of saving the tooth and being able to restore the area.
