Root canal is a dental treatment undertaken if your tooth pulp is infected. You may require root canal if you have a cavity due to bacteria in your mouth intruding tooth pulp and causing inflammation. This treatment involves 3 stages, Extirpation-extracting infection, Instrumentation-filling the pulp, and obturation-fixing the dental crown. Symptoms such as excruciating pain, discoloured tooth, swollen gums, loose tooth may indicate the problem. It is important to attend the dental issue in time otherwise if untreated it will lead to serious problems like damaging jawbone or infection might spread. It will take almost a week to recover from Root Canal.
