Throbbing pain after a root canal can be concerning. While root canal treatment aims to relieve pain by removing infected pulp, some discomfort can occur during the healing process. Understanding the potential reasons behind this throbbing can help clarify when it is a normal part of recovery and when it might signal a need for further dental attention.
Understanding Post-Procedure Throbbing
Mild, temporary throbbing or discomfort is a normal part of the healing process. The manipulation of tissues surrounding the tooth during the root canal can cause irritation, leading to this sensation. This discomfort typically lessens over a few days.
A common cause of throbbing pain is a “high bite” or occlusal trauma, where the treated tooth or its new crown/filling sits slightly higher than other teeth. This uneven pressure can inflame the periodontal ligament, leading to discomfort when biting or chewing. An adjustment by the dentist can usually resolve this issue quickly.
Sometimes, if any bacteria or infected tissue remains within the tooth’s intricate canal system, it can lead to continued inflammation and throbbing. This can happen if canals are not thoroughly cleaned during the initial procedure. In such cases, the original infection may not have been completely eradicated, causing persistent pain.
Re-infection is another possibility, occurring if new bacteria enter the treated tooth. This can happen due to an incomplete seal of the tooth, a crack in the tooth, or a delay in placing the permanent crown or filling, leaving the tooth exposed. Poor oral hygiene after the procedure can also contribute to new bacterial growth.
A root fracture can also cause throbbing pain. These fractures can be difficult to diagnose as they may not be visible on X-rays until severe. Bacteria can infiltrate the tooth through these cracks, leading to ongoing pain and potential re-infection.
When to Seek Dental Care
While some discomfort is expected, certain signs indicate that you should seek dental attention. If the pain is severe or worsens after a few days, rather than improving, it warrants contacting your dentist. Pain that does not respond to over-the-counter pain relievers is also a red flag.
Swelling in the face, gums, or jaw should prompt immediate contact with your dentist. The presence of a fever can indicate a spreading infection. A bad taste in the mouth or pus draining from the treated area also suggests a potential infection or abscess.
Throbbing that persists beyond a few days or weeks should be evaluated by a dentist. Prompt communication with the treating dentist is important for proper diagnosis and treatment. Early intervention can prevent further complications and help preserve the treated tooth.
