Traumatic Dental Injuries

Traumatic dental injuries are physical injuries to the teeth, gums, and supporting structures caused by accidents, sport, or other impacts. These injuries can range from minor chips to severe fractures or tooth displacement. Prompt treatment is essential for the best outcomes.

Common Types of Dental Trauma

1. Chipped or Fractured Teeth

  • Description: Chipped teeth involve the loss of a small part of the enamel, while fractures can extend deeper into the tooth. 
  • Treatment:
    • ​Minor Chips are usually repaired with dental bonding or a simple filling.
    • Deep fractures may require crowns, and if the pulp is affected, root canal therapy could be necessary.

2. Tooth Displacement (Luxation)

  • Description: A tooth can be displaced from its normal position, such as being pushed deeper into the gum (intrusion) or partially out of its socket (extrusion).
  • Treatment:
    • The tooth can be repositioned and stabilized with a splint.
    • In some cases, root canal therapy may be required if the pulp is damaged. However, children between the ages of 7 and 12 may not need root canal treatment, as their teeth are still developing. In these cases, the endodontist will monitor the healing closely and intervene only if unfavorable changes arise.

3. Avulsed (Knocked Out) Tooth

  • Description: A tooth that has been completely knocked out of its socket.
  • Treatment:
    • ​For permanent Teeth: If the tooth is reinserted quickly, it can often be saved. It should be kept moist ( in milk or saliva) and placed back into the socket by a dentist. Immediate care is essential, and ideally, the tooth should be reinserted within 30 minuites.
    • For Primary Teeth: A knocked - out primary tooth should not be replanted to avoid damaging the developing permanent tooth underneath.
    • After the tooth is stabilized  with a splint, a root canal may be performed one or two weeks later to preserve the tooth.

4. Cracked Teeth

  • Description: Cracks can range from minor surface - level fractures to more serious ones extending deeper into the tooth, potentially reaching the root. 
  • Treatment:
    • ​Minor Cracks can be treated with bonding or fillings.
    • More severe cracks may require crowns, and if the crack reaches the pulp, root canal therapy may be necessary to save the tooth.

5. Root Fracture 

  • Description: A fracture that occurs along the root of the tooth, either horizontally or vertically.
  • Treatment: 
    • ​Horizontal Root Fractures: These may be treated by stabilizing the tooth with a splint to allow healing. 
    • Vertical Root Fractures: These are more serious and often require extraction, though in some cases, surgery or an apicoectomy may be performed to save the tooth.

6. Root Resorption

  • Description: Root resorption occurs when the body starts to break down the root structure, often following trauma, weakening the tooth.
  • Treatment:
    • ​Early detection is crucial. Root canal therapy can help remove the resorptive tissue and stop further damage.
    • In advances cases, the tooth may need to be extracted if it cannot be saved.

7. Soft Tissue Injuries

  • Description: Injuries to the gums, lips, tongue, or cheeks caused by trauma.
  • Treatment:
    • ​Minor injuries may heal on their own or with stitches.
    • The dentist will clean the wound and may prescribe medication to prevent infection.

8. Traumatic Dental Injuries in Children

  • Description: Children are particularly susceptible to traumatic dental injuries due to their active lifestyles and participation in sports. Common causes include falls, collisions, and sports - related accidents. Treatment for children may vary slightly, as their teeth and jaws are still developing.
  • Preventing: Using mouthguards during sports and ensuring a safe environment can significantly reduce the risk of injuries.
  • Treatment: The approach to treating traumatic dental injuries in children is similar to adults but may involve considerations for their developing teeth. Avulsed primary (baby) teeth are typically not replanted, as this can lead to complications for the underlying permanent teeth. When a child's permanent teeth are not fully developed at the time of injury, they require special care and monitoring. Not all cases will need root canal treatment. Immature permanent teeth have the potential for continued root development due to the blood supply and the presence of stem cells. An endodontist can help stimulate further root growth as part of the healing process.

​Treatment for Traumatic Dental Injuries

The treatment for traumatic dental injuries depends on the severity and type of injury. Advanced imaging, such as CBCT scans, helps develop a precise treatment plan. Treatments may include repositioning, splinting, root canal therapy, crowns, or, in severe cases, tooth extraction. Early intervention is critical for saving the tooth and preventing complications.
