Can a root canal tooth get infected again even months or years after treatment? Although root canal treatment is designed to remove infection and preserve the natural tooth, reinfection can sometimes occur because of complex canal anatomy, new decay, leakage around a restoration, cracks, or other dental problems.

A previously treated tooth can sometimes become painful or infected again due to missed canals, complex root anatomy, leakage, or hidden infection. Fortunately, Root Canal Retreatment may help remove persistent infection and give your natural tooth another chance.
