When a permanent tooth with a closed apex is avulsed and the tooth has not been out of the mouth for long, the goal is to replant and stabilize it while minimizing future root resorption and ankylosis. Treating the root surface with fluoride before replantation helps achieve that by creating a fluoride-treated layer on the root that reduces osteoclast activity and slows resorption once the tooth is replanted. A 2% sodium fluoride soak for about 20 minutes is a common, targeted step to modify the root surface in a way that lowers the risk of external resorption after replantation. This step addresses the biological response at the root surface more directly than rinsing alone, which mainly cleans debris. Other steps like gentle rinsing, saline irrigation, and socket suturing are important for cleansing and stabilization, but the fluoride soak specifically helps improve long-term prognosis by reducing resorption after replantation.
