The aim of endodontics is to preserve the remaining tooth portion in preference to removal, an implant placement or a denture.
Endodontics involves treatment of the root canal system after it is breached by infection or trauma.
Root canal treatment takes time for the infection in and around the tooth to resolve, which may take 1 – 12 months. Relief of pain from a pulpally treated nerve system is attained anywhere from immediately afterward to 1 week post treatment depending on the clinical and settling down processes. Root canal treatment is a multi-stage treatment that typically takes 1-6 months to complete that also requires a sealed and protective restoration while being treated.
Most root filled teeth subsequently require full cover restorations because much tooth volume is missing, leaving a tooth susceptible to fracture and possible irreversible damage.
Temporary fillings that are not crown embracing and left for a long time also predispose the tooth to crown and root failure.
A badly broken down tooth may not have enough structure to support a crown. In such an instance the tooth can be removed or retained in low profile under a denture, providing support and importantly preserving bone in the region.
It should be noted that endodontics is separate to the restorative aspects of treatment of the crown of the tooth as it involves only the root canal system. Follow on crown processes of root filled teeth such as post placement, core build up and crown or bridgework have individual fees and are quoted separately.
