A root canal saves a damaged tooth, but some people experience pain when biting afterward. Is Tooth Pain After Root Canal When Biting Normal? Understanding the causes can help determine if your discomfort is part of the healing process or a sign of a complication.
What is a Root Canal?
A root canal is a dental procedure that removes infected pulp inside a tooth, cleans the root canals, and seals the tooth to prevent further damage. It is a highly effective treatment for tooth decay and infection.
Why Does Pain Occur After a Root Canal?
Pain after a root canal can result from:
- Inflammation in the surrounding tissues
- A high filling that alters bite alignment
- An undetected crack in the tooth
- Infection that persists or develops post-treatment
Normal vs. Abnormal Tooth Pain After a Root Canal
Normal Pain: Mild discomfort that fades within a few days to a week.
Abnormal Pain: Intense, persistent pain that worsens over time, indicating a possible issue.
Common Causes of Tooth Pain After Root Canal When Biting
1. Bite Misalignment and High Fillings
If the filling or crown is too high, it can cause pressure on the tooth when biting. A dentist can adjust the height to relieve discomfort.
2. Infection After a Root Canal
Even after cleaning, bacteria can sometimes linger, leading to infection. Symptoms include swelling, pus, and throbbing pain.
3. Cracked Tooth Syndrome and Root Canal Pain
A hidden crack in the tooth can lead to persistent pain despite treatment.
4. Residual Nerve Sensitivity
Though the nerve inside the tooth is removed, surrounding nerves can still cause discomfort due to residual inflammation.
How to Treat Post-Root Canal Pain?
- Pain Relievers: Ibuprofen or acetaminophen can help reduce inflammation.
- Cold Compress: Apply ice to the outside of the cheek for swelling.
- Dental Adjustment: If a high filling is causing pain, your dentist can reshape it.
When to Seek Emergency Dental Care?
- Severe, persistent pain beyond two weeks
- Swelling, fever, or pus discharge
- Difficulty chewing or extreme sensitivity
Preventing Pain After a Root Canal
- Follow your dentist’s post-care instructions.
- Maintain good oral hygiene.
- Avoid chewing hard foods on the treated tooth.
