Root Canal Failure Causes

Identifying Failure & Retreatment

Even successful procedures can encounter issues years later. L4RG helps you spot the signs early to prevent tooth loss.

Common Causes:

  • Undetected Canals: Complex root anatomy may lead to narrow or curved canals being missed during the initial cleaning.
  • Structural Damage: Cracks in the tooth or a delay in placing a protective crown can allow bacteria to re-enter.
  • New Decay: New cavities can expose the root canal filling material to saliva and bacteria, causing reinfection.
