Root canal therapy is necessary when the dental pulp inside a tooth becomes infected or inflamed due to deep decay, cracks, trauma, or other factors. Symptoms may include severe toothache, sensitivity to temperature, swelling, or abscess formation. Root canal therapy aims to remove the infected pulp, clean the canals, and seal the tooth to alleviate pain and save it from extraction.

The duration of a root canal treatment depends on various factors, such as the tooth's complexity, the number of canals, and the extent of infection. On average, a single-visit root canal can take about 60-90 minutes, while multiple-visit treatments may span across a few weeks. Your endodontist will provide a more accurate estimate based on your specific case.

Endodontic procedures are typically performed under local anesthesia, ensuring that patients are comfortable and experience minimal discomfort during the treatment. Advances in technology and techniques have made modern endodontic procedures more efficient, and patients generally report less pain and faster recovery compared to the past.

In many cases, a tooth with a failed root canal can still be saved through endodontic retreatment or endodontic surgery. However, the success of the treatment depends on the specific circumstances and the availability of suitable treatment options. It is important to consult with an endodontist to evaluate the tooth's condition and explore the appropriate treatment approach.

The primary alternative to root canal therapy is tooth extraction, which involves removing the infected tooth. However, tooth extraction is generally considered a last resort since it leads to the loss of a natural tooth. Following extraction, replacement options such as dental implants, bridges, or removable dentures may be considered to restore the appearance and function of the missing tooth.
