What is root canal treatment and when is it performed?

Root canal treatment is a treatment used when the nerve and vascular tissue (pulp) inside a tooth has been damaged by decay, infection, or trauma. The goal is to preserve the tooth without extraction and to clear the infection to restore chewing function. Root canal treatment is necessary in cases of deep decay, abscesses, fractures, or severe sensitivity. If left untreated, it can lead to tooth loss or the spread of infection to the jawbone.
