Traumatic Injuries

Injuries to the tooth can cause teeth to be pushed sideways, out of, or into its socket.. We will reposition and stabilize your tooth. Root canal treatment is usually needed for permanent teeth that have been dislodged and should be started a few days following injury. Medications such as calcium hydroxide may be placed inside the tooth as part of the root canal treatment. A permanent root canal filling will be placed at a later date.

Avulsed Teeth
If an injury causes a tooth to fall out of your mouth, time is of the essence. The tooth should be handled very gently, avoiding touching the root surface itself. If it is dirty, quickly and gently rinse it in water. Do not use soap or any other cleaning agent, and never scrape or brush the tooth. If possible, the tooth should be placed back into its socket as soon as possible. The less time the tooth is out of the socket, the better the chance for saving the tooth.avulsed_300x214.png

If you cannot put the tooth back in its socket, it needs to be kept moist in special solutions that are available at many local drugstores (Save-A-Tooth). If those solutions are unavailable, you should put the tooth in milk. Doing this will keep the root cells in your tooth moist and alive for a few hours. Another options is to simply put the tooth in your mouth between your gum and cheek. Do not place the tooth in regular tap water because the root surface cells do not tolerate it.

Once the tooth has been put back in its socket, we will evaluate it and check for any other dental and facial injuries. If the tooth has not been placed back into its socket, we will clean it carefully and replace it. A stabilizing splint will be placed for a few weeks. Depending on the stage of root development, we may start root canal treatment a week or two later. A medication may be placed inside the tooth followed by a permanent 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 influence the chances of saving the tooth. Again, immediate treatment is essential. Taking all these factors into account, we may discuss other treatment options with you.

Injuries in children
An injured, immature tooth may need one of the following procedures to improve the chances of saving the tooth:

Injuries in children



This procedure encourages the root to continue development as the pulp is healed. Soft tissue is covered with medication to encourage growth. The tip of the root (apex) will continue to close as the child gets older. In turn, the walls of the root canal will thicken. If the pulp heals, no additional treatment will be necessary. The more mature the root becomes, the better the chance to save the tooth.


In this case, the unhealthy pulp is removed. The doctor will place medication into the root to help a hard tissue form near the root tip. This hardened tissue provides a barrier for the root canal filling. At this point, the root canal walls will not continue to develop, making the tooth susceptible to fractures. So it is important to have the tooth properly restored by your dentist.
