The most common emergency dental issues include severe toothaches, knocked-out teeth, chipped or broken teeth, and dental abscesses. Other urgent problems include loose or lost fillings or crowns, as well as soft tissue injuries to the gums or lips. These situations often cause significant pain or discomfort and require immediate attention to prevent further damage or infection. Quick action, such as preserving a knocked-out tooth or addressing a dental abscess, can help save the tooth and reduce the risk of complications.
