How often should I change the medicine during root canal treatment

Root canal treatment is a common and effective method for treating dental diseases. How often should the medicine be changed during root canal treatment?

Most people will undergo root canal treatment, which requires dressing changes, usually every three or seven days after root canal treatment.

1. How often should the medicine be changed during root canal treatment?

Root canal therapy is the most commonly used and effective treatment method for pulp disease and periapical periodontitis internationally. After root canal treatment, the interval between dressing changes should be determined based on the tooth root and the medication used. Normally, you should go to the hospital to change the dressing three to seven days after root canal treatment. Be sure to follow your doctor's orders and return for follow-up visits on time to ensure the effectiveness of root canal treatment.

2. Root canal treatment steps

Step 1: Root canal preparation

Before root canal preparation, preoperative evaluation of root canal treatment, pulp chamber preparation and working length measurement are required, followed by the root canal preparation stage. There are two methods of root canal preparation, and different preparation methods are used depending on the instrument selected. When doing root canal preparation for endodontic treatment, it is important to emphasize that since the root canal system is very complex, no instrument or preparation method can reach the entire root canal system, so the combination of mechanical preparation and chemical preparation is very important.

Step 2: Root canal disinfection stage

In root canal treatment, it is recommended that teeth with vital pulp or infection limited to the coronal pulp can use the one-time method, while others can undergo root canal sealing.

Step 3: Root canal filling stage

During root canal treatment, when filling the root canal, it is important to grasp the timing of filling. Generally, filling can be performed when there are no subjective symptoms, no obvious percussion pain, no odor in the root canal, no exudation, and no symptoms of acute periodontitis. There is no need to wait until all symptoms disappear, nor does it necessarily have to wait for the fistula to heal completely. Repeated filling can easily cause greater irritation to the periapical region. As for filling methods, the cold gutta-percha lateral pressure method is still the mainstream, while the hot gutta-percha method is the future trend.
