If germs in the saliva get under the filling material before the filling is placed, the canal can become reinfected. If the patient doesn't maintain proper oral hygiene, new cavities can form on the same tooth
Persistent extraradicular infection in root-filled asymptomatic human tooth: scanning electron microscopic analysis and microbial investigation after apical microsurgery. J Endod. 2011;37(12):1696-700. 13. Siqueira Jr JF. Aetiology of root canal treatment failure: why well-treated teeth can fail. ...
Because these are signs of dental decay, the root canal recipient must receive regular dental check-ups with periodic x rays to avoid further disease in the tooth. The restored tooth may last a lifetime. However, with routine wear, the filling or crown may eventually need to be replaced. ...
The apical end and the crown were cut off perpendicular to the long axis of each tooth by using a rotating diamond saw under water-cooling. Afterward, the root canal was enlarged to a standard diameter of approximately 2 mm with a round tungsten carbide bur. The root cementum was removed ...

Nevertheless, electrospun fibers may not be capable of complete eradication of root canal infections, especially due to the complex anatomical geometry of the root canal system (e.g., the existence of lateral canals and apical ramifications), which may be difficult to access by a solid drug-...
