Traumatic Injuries
Traumatic dental injuries often occur as a result of an accident or sports injury. The majority of these injuries are minor – chipped teeth. It’s less common to dislodge your tooth or have it knocked completely out but these injuries are more severe. Treatment depends on the type, location and severity of each injury. Regardless of the extent of the injury, your tooth requires immediate examination by a dentist or an endodontist. Sometimes, your neighboring teeth suffer an additional, unnoticed injury that can only be detected by a thorough dental exam.
If you’ve chipped or fractured your tooth’s crown, it’s likely it can be repaired either by reattaching the broken piece or by putting a tooth-colored filling in place. If a significant part of your tooth crown is broken off, an artificial crown or “cap” may be needed to restore it.
When the pulp is exposed or damaged after a crown fracture, root canal treatment may be needed. These injuries require special attention. If breathing through your mouth or drinking cold fluids is painful, bite on clean, moist gauze or cloth to help relieve symptoms until reaching your dentist’s office. Never use topical oral pain medication (such as Anbesol®) or ointments, or place aspirin on the affected areas to eliminate pain symptoms.
Injuries in the back teeth, such as fractured cusps, cracked teeth require root canal treatment and a full coverage crown to restore function your tooth if the crack extends into the root. More seriously injured split teeth may require extraction.
During an injury, a tooth may be pushed sideways, out of or into its socket. Your endodontist or general dentist will reposition and stabilize your tooth. Root canal treatment is usually needed for permanent teeth that have been dislodged and should be started several days following the injury. Medication may be put inside your tooth as part of the root canal treatment; once treatment is complete and has been deemed successful a permanent root canal filling or crown will be put in place at a later date.
Children ages 12 and under may not need root canal treatment since their teeth are still developing. New research indicates that stem cells present in the pulps of children can be stimulated to complete root growth and heal the pulp following injuries or infection. When a child’s tooth is injured, an endodontist or dentist will monitor the healing carefully and intervene immediately if any unfavorable changes appear. Multiple follow-up appointments are likely to be needed.
If one of your teeth is completely knocked out of your mouth, see an endodontist or dentist immediately! Time is of the essence and if you receive treatment quickly, preferably within 30 minutes, there is a chance to save your tooth.
If this happens to you, handle a knocked-out tooth very carefully and don’t touch the root surface and keep the tooth moist. If possible, put it back into the socket. If it can’t be replaced in the socket put it in milk or in an emergency tooth preservation kit (such as Save-a-Tooth®), or even in your mouth next to your cheek.
Your endodontist or dentist will evaluate the tooth, place it back in its socket and examine you for any other dental and facial injuries. A stabilizing splint will be placed for the next few weeks. Your Endodontist may start root canal treatment based upon the stage of root development. The length of time the tooth was out of your mouth and the way the tooth was stored, may influence the type of treatment you receive.
A traumatic injury to your tooth may also result in a horizontal root fracture. The location of the fracture determines the long-term health of your tooth. The closer a fracture is to the root tip, the better the chances of success and long-term health; fractures closer to the gum line are more debilitating for your tooth. Sometimes, stabilization with a splint is required while the tooth heals.
Do traumatic dental injuries differ in children?
Chipped primary (baby) teeth can be esthetically restored. Dislodged primary teeth can, in rare cases, be repositioned. However, primary teeth that have been knocked out typically should not be replanted because it may cause further and permanent damage to the underlying permanent tooth that is growing inside the bone.
Children’s permanent teeth that are not fully developed at the time of the injury need special attention and careful follow-up, but not all of them will need root canal treatment. In an immature permanent tooth, the blood supply to the tooth and stem cells in the region may enable your dentist or endodontist to stimulate continued root growth. An injured immature tooth may need one of the following procedures to improve the chances of saving the tooth:
The treatment you receive for your cracked tooth is important because it will relieve pain and reduce the likelihood that the crack will worsen. Once treated, most cracked teeth continue to function and provide years of comfortable chewing.
