Splint duration after a root fracture is tied to letting the fracture stabilize while the surrounding tissues heal. For an apical fracture, the prognosis is favorable, so a flexible splint kept in place for about four weeks provides the necessary stabilization without over-restricting tooth movement. A flexible splint supports physiologic mobility, which promotes proper healing along the fracture line and minimizes risks such as ankylosis or resorption that can come with prolonged rigid immobilization.

After about four weeks, if the tooth remains stable and healing is progressing, the splint is removed and the dentist continues to monitor clinically and radiographically. If there were more displacement, a cervical-third fracture, or other complications, the duration might be extended, but for an apical fracture, four weeks is the standard recommendation. Longer immobilization for this scenario is not typical and could hinder healing.
