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.
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.
