Update Date: 2024-05-30 Source: Network

When using a deactivating agent, it can stimulate the nerves and generally cause pain. However, some individuals may not experience pain after applying the deactivating agent, which is usually considered normal. If there are any other discomforts, it is recommended to seek medical attention promptly.

I. Is it normal not to feel pain after applying a deactivating agent?

It is normal not to feel pain after applying a deactivating agent. Some dental nerves may not be very active and may be close to necrosis. Additionally, the pressure inside the pulp cavity may not be significant. Therefore, after applying the deactivating agent, the dental nerve gradually becomes necrotic, resulting in no pain. Generally, deactivating agents are slow-acting and require about 10-14 days of application. It is crucial to attend follow-up appointments on time, as long-term residual effects can lead to pain or other adverse effects. After removal, comprehensive root canal treatment should be performed.

II. Steps of Root Canal Treatment Step 1: Root Canal Preparation

Before root canal preparation, preoperative evaluation, pulp cavity preparation, and determination of working length are required. Then, the actual root canal preparation phase begins. There are two methods for root canal preparation, depending on the choice of instrumentation. It is important to emphasize that the root canal system is complex, and neither mechanical nor chemical preparation methods can reach the entire system. Therefore, a combination of both is crucial.

Step 2: Root Canal Disinfection

During root canal treatment, experts recommend using the one-time method for teeth with live pulp or infection limited to the coronal pulp. For other cases, canal sealing with medication is recommended.

Step 3: Root Canal Filling

During root canal treatment, it is essential to grasp the timing of canal filling. Generally, filling can be performed when there are no subjective symptoms, no significant tenderness to percussion, no odor or exudate within the canal, and no acute apical periodontitis symptoms. It is not necessary to wait for all symptoms to disappear or for fistulas to heal completely, as repeated sealing can cause greater irritation to the apical region.
