Broken or Knocked-out Teeth
Broken or Knocked-Out Teeth Overview
Each individual tooth is composed of calcium and several other organic components. It is divided into 3 layers: enamel, dentin, and pulp - each layer having a specific role.
Anatomically, the tooth is made up of the crown and root. The crown is the visible portion you see inside the mouth. The root extends beneath the gum line. The tooth is positioned in a bony socket called the alveolus. It is anchored by a ligament and protected by the gums.
The 20 primary or baby teeth are replaced, beginning at about 6 years, with 32 adult or permanent teeth. Injury to teeth, especially permanent teeth, can be painful and serious.
Broken or Knocked-Out Teeth Causes
Dental injuries to the teeth commonly occur with falls, assaults, sports activities, child abuse, and multiple trauma such as an auto collision.
