  • The exposed root surface of the displaced tooth is cleansed with saline before repositioning.
  • Reposition the tooth by gently re-inserting it into the tooth socket with axial digital pressure (local anesthesia is usually not necessary).
  • Stabilize the tooth for 2 weeks using a flexible splint.

Monitoring the pulpal condition is essential to diagnose associated root resorption.

Open apex: Revascularization can be confirmed radiographically by evidence of continued root formation and pulp canal obliteration and usually a return to a positive pulp response to sensibility testing.

Closed apex: A continued lack of pulp response to sensibility testing should be taken as evidence of pulp necrosis together with periapical rarefaction and sometimes crown discoloration.

Patient instructions

  • Soft food for 1 week.
  • Good healing following an injury to the teeth and oral tissues depends, in part, on good oral hygiene. Brushing with a soft brush and rinsing with chlorhexidine 0.1 % is beneficial to prevent accumulation of plaque and debris.


  • Clinical and radiographic control and splint removal after 2 weeks. Clinical and radiographic control at 4 weeks, 6-8 weeks, 6 months, 1 year and yearly for 5 years.
