A root canal (endodontic treatment) removes infected or damaged pulp from the inner chamber of a tooth, cleaning and sealing the canals to prevent further infection. While the procedure eliminates the severe pain of the original infection, some temporary discomfort is normal as the surrounding tissues heal. Understanding the expected timeline can help manage the recovery process.
Expected Discomfort After the Procedure
The discomfort immediately following a root canal is typically mild to moderate, resulting directly from the cleaning process. Although the nerve is removed, the ligaments and tissues surrounding the root tip become irritated and inflamed by the instrumentation used. This soreness is the body’s natural inflammatory response to the deep cleaning.
The peak period for soreness usually occurs within the first 24 to 48 hours after treatment. During this time, you may notice tenderness when chewing or applying pressure, along with general dull aching or throbbing. A temporary filling that is slightly high can also cause sensitivity when biting down.
This discomfort should steadily decrease each day following the procedure. Most patients report significant improvement after the first two days. By the three to seven-day mark, most people feel comfortably healed, with only minor sensitivity remaining. Consistent improvement is a normal sign that the tooth and surrounding bone are recovering.
Managing Post-Procedure Discomfort
Managing post-treatment soreness is effective with over-the-counter medications. Non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen are recommended because they relieve pain and reduce inflammation in the healing tissues. Acetaminophen is also a suitable option for pain relief.
Begin taking these medications before the local anesthetic fully wears off, following the provided dosage instructions. Avoid chewing on the treated tooth until the final restoration, often a crown, is placed. Eating soft foods for the first few days minimizes pressure on the healing area.
Applying a cold compress to the outside of the cheek for short intervals during the first day can help reduce initial swelling. Maintaining excellent oral hygiene, including gentle brushing and flossing, is crucial. After the first 24 hours, rinsing with warm salt water can soothe irritated gums and promote a clean healing environment.
Identifying When Pain Is Abnormal
While some discomfort is expected, certain warning signs indicate the pain is not typical healing soreness and requires immediate dental attention. Abnormal pain is severe, intense, and worsens after the first few days instead of improving. Throbbing pain that persists beyond seven days may signal an issue needing re-evaluation.
Several symptoms should prompt a call to your dental professional:
- Swelling that increases or extends into the face or jaw.
- The presence of pus or drainage from the treated area.
- Fever or a general feeling of illness.
- Sharp, sudden pain when biting down after the first week.
These issues can be caused by factors such as an undiagnosed crack in the root, an incompletely cleaned canal, or an unresolved infection.
A poorly fitting restoration, such as a temporary filling that is too high, can also cause sharp pain when biting and may require a simple adjustment. The key distinction is that normal soreness decreases daily and is manageable. Abnormal pain is severe, unresponsive to medication, and either remains constant or gets worse. Promptly contacting your dentist is necessary to ensure the long-term success of the treatment.
