Stage 1 of root canal treatment begins with an evaluation of the tooth to determine the need for a root canal. Following this, an initial cleaning is performed to control the bacterial infection within the tooth. Antibacterial solutions are used for rinsing, and medication may be applied. To protect the tooth during the treatment process, a temporary filling is placed before proceeding to stage two. Stage 2, also known as the follow-up clean and medication stage, typically occurs either on the same day as stage one or 1-2 weeks later. This stage involves a more comprehensive cleaning of the root canal to remove any remaining bacteria. X-rays may be taken to ensure the complete cleaning of the entire canal and medication is applied to treat the infection. Stage 3 focuses on filling the root canal once the infection has been eradicated, and symptoms have subsided. This stage generally takes place 4-6 weeks after stage two. Specialized rubber points are placed into the root canals, and the canal is sealed. Depending on the condition of the tooth, a temporary or permanent filling may be inserted to restore its integrity and function.
