A root canal is a dental procedure performed to treat a tooth that has become infected or severely decayed. Inside each tooth, there is a soft tissue called the pulp, which contains nerves, blood vessels, and connective tissue. When the pulp becomes infected or inflamed due to deep decay, trauma, or repeated dental procedures, it can cause severe pain and lead to an abscess if left untreated.
During a root canal procedure, the infected or damaged pulp is removed, and the inside of the tooth is cleaned, disinfected, and sealed to prevent further infection. The tooth is then restored with a filling or crown to protect and strengthen it.
What the patient can expect during a root canal procedure?
1. Numbing: The dentist will administer local anesthesia to numb the area around the tooth, ensuring you don't feel pain during the procedure.
2. Accessing the Tooth: The dentist will create an opening in the crown of the tooth to access the pulp chamber and root canals.
3. Removing the Infected Pulp: Using specialized instruments, the dentist will carefully remove the infected or damaged pulp from the tooth's interior.
4. Cleaning and Shaping: The root canals are cleaned, shaped, and disinfected to remove any remaining bacteria and debris.
5. Filling and Sealing: The cleaned root canals are filled with a biocompatible material, usually gutta-percha, and sealed to prevent reinfection.
6. Restoration: Depending on the extent of damage to the tooth, a filling or crown may be placed to restore its function and appearance.
After the root canal, patients can expect some mild discomfort or sensitivity, which can usually be managed with over-the-counter pain medication. The tooth may feel slightly different than other teeth, but this should subside as it heals. It's important to follow any post-operative instructions provided by the dentist and attend follow-up appointments as needed for optimal healing and long-term oral health.
