Root Canal Pressure After 5 Years: Causes and Next Steps
Pressure/pain years after RCT suggests a new or persistent problem. Potential causes:
- Incomplete Initial Treatment: Missed canals, inadequate cleaning/sealing.
- Root Fracture: Vertical/horizontal crack compromises seal; often non-restorable.
- External Root Resorption: Immune-mediated root breakdown; progressive.
- Periapical Lesion: Cyst or granuloma from chronic inflammation.
- New Infection: Leaking restoration, recurrent decay, cracked crown.
- Occlusal Trauma: High bite on the tooth; adjust occlusion.
- Sinus Involvement: Maxillary posterior roots near sinus; sinusitis mimics tooth pressure.
- Referred Pain: TMJ, adjacent tooth, myofascial.
Required: Dental Evaluation
Clinical exam, percussion, palpation, CBCT (3D imaging) to diagnose. Treatment: retreatment, apicoectomy, extraction/implant, or occlusal adjustment.
