Persistent Tooth Pain After Root Canal: Causes & What to Do
Why Molar Hurts 2 Months Post-Root Canal
- Incomplete root canal: Residual infected pulp → inflammation/pain.
- Need for retreatment: Original treatment failed; re-infection or inadequate initial procedure.
- Fractured tooth: Crack allows bacterial entry → infection.
- Sinusitis: Sinus inflammation near upper molars mimics tooth pain.
- Trigeminal neuralgia: Facial nerve pain mistaken for toothache.
Could Nerve Remain?
Yes, if root canal was incomplete – nerves in narrow/curved canals can be missed, causing persistent pain.
Action
See your dentist immediately for evaluation and appropriate treatment.
