Sometimes, a tooth that has been injured will appear intact but may have suffered damage to its internal tissues. A tooth that begins to darken in color weeks or months after an injury may be a sign that the tissue has died within the tooth. This condition necessitates extraction or root canal treatment. An effective way to prevent many dental injuries is to provide children with a mouth guard since many injuries occur while playing team sports. Not all dental emergencies deal with broken or knocked out teeth.
Tooth decay is a disease that still exists in many children.
A cavity left untreated could result in severe pain and can even lead to infection. A child who cannot sleep because of a toothache is exhibiting a classic sign of an extensive cavity affecting the pulp of the tooth. If swelling is noticed around the gums of a tooth, this is possibly the result of a cavity causing an infection. Place a cold compress over the area and see a dentist immediately. Dental accidents can be stressful to both a child and the parent.
