Most traumatic dental injuries occur in children, but people of all ages can be affected. Whether the injury is a result of an automobile accident, a sports mishap, an altercation or a bad fall, the severity and type of injury will determine the treatment necessary.
There are a number of common injuries that occur to teeth. Many of them affect the inner soft tissues of the tooth, known as the dental pulp. When the pulp becomes injured or inflamed, root canal treatment may be needed.
Types of Injuries
Chipped Teeth
Most chipped teeth can be repaired with a simple filling. Sometimes a chip will expose the pulp of the tooth. Some exposures can be treated by placing a filling over the injured area. Other exposures, however, may require root canal treatment.
Injuries in the back teeth often include fractured cusps, cracked teeth and the more serious split teeth. Cracks may or may not extend into the root. If the crack does not extend into the root, the tooth can usually be restored by your dentist with a full crown. If the crack does extend into the root and affects the pulp, root canal treatment is usually necessary in an attempt to save all or a portion of your tooth.
Dislodged Teeth
| During an injury, a tooth may be pushed into its socket. This can be one of the more serious injuries. Your endodontist or general dentist may reposition and stabilize your tooth. Root canal treatment is usually started within a few weeks of the injury, and a medication, such as calcium hydroxide, may be put inside the tooth. A permanent root canal filling will be placed at a later date. You should continue to have the tooth monitored periodically by your dentist to assure proper healing. |  |

Sometimes a tooth is pushed partially out of the socket. Repositioning and stabilization of the tooth are usually necessary. If the pulp remains healthy, no additional treatment may be needed. If the pulp is injured, your dentist or endodontist may need to start root canal treatment. Medication, such as calcium hydroxide, may be placed inside the tooth and should be followed by a permanent root canal filling at a later date.
Avulsed Teeth
If you cannot put the tooth back in its socket, be sure to keep it moist. The less time the tooth spends drying out, the better the chance of saving the tooth. Solutions to keep your tooth moist are available at local drug stores. You can also put the tooth in milk or a glass of water with only a pinch of salt, or you can simply put it in your mouth between your gum and cheek. Bring your tooth to the dentist immediately.
Root Fractures
Sometimes stabilization with a splint is required for a period of time. If the tissue inside the tooth is damaged, root canal treatment may be needed. A medication may be placed in the canal to prepare the fracture site for the eventual root canal filling.

If a tooth is completely knocked out of your mouth, time is of the essence. If this type of injury happens to you, pick up your tooth by the crown, or chewing portion. Try not to touch the root. If the tooth is dirty, gently rinse it in water. Do not use soap or any other cleaning agent. If possible, place the tooth back into its socket. Go to the dentist immediately.
If the tooth has been put back in its socket, your dentist may stabilize the tooth with a splint and check for any other facial injuries. If the tooth has not been put back into its socket, your dentist will examine the tooth to determine if it is still intact and check for other facial injuries. Your dentist will clean the the tooth carefully and place it gently back into the socket. Your tooth may need to be stabilized with a splint for a period of time. Depending on the stage of root development, your dentist or endodontist may start root canal treatment. A medication may be placed in the tooth followed by a permanent root canal filling at a later date. The length of time the tooth was out of the mouth and the way the tooth was stored before reaching the dentist may influence the type of treatment you receive. You should contact your physician to see if a tetanus booster is necessary.
A traumatic injury to the tooth may also result in a horizontal root fracture. The location of the fracture determines the long-term health of the tooth. If the fracture is close to the root tip, the chances for success are better. If the fracture does not result in the two pieces of the root being separated, there is also a better chance for success. However, the nearer the fracture is to the chewing surface of the tooth, the poorer the long-term success rate, regardless of whether the pieces are separated.
