For how long should a tooth be splinted if it sustains a root fracture?

The appropriate duration for splinting a tooth that has sustained a root fracture is typically 2 to 4 months. This timeframe allows for adequate healing of the periodontal ligament as well as the supporting structures around the tooth. During this period, the fractured root may begin to stabilize and heal, which is crucial to preserving the vitality of the tooth and minimizing potential complications, such as further tooth mobility or infection.

The rationale behind the 2 to 4 months splinting is based on the physiological healing processes that occur following a root fracture. Splinting for this length of time provides sufficient stability, allowing for proper healing while keeping the tooth functional.

While splinting the tooth for shorter periods, such as 1 to 2 weeks or 2 to 4 weeks, may provide initial support, this duration often proves to be insufficient for the healing of more severe fractures. On the other hand, prolonging splinting beyond 4 months could lead to complications, including ankylosis or root resorption, and it is generally not recommended unless specific circumstances dictate otherwise. Therefore, understanding the healing time for root fractures is crucial for optimal patient outcomes.
