Experiencing tooth pain after a root canal, especially when biting down, can be frustrating and concerning. While a root canal aims to eliminate infection and save your tooth, post-procedure discomfort isn't uncommon. Understanding the potential causes and seeking appropriate care is crucial for resolving the issue and ensuring long-term oral health.
Why Does My Tooth Still Hurt After a Root Canal When I Bite?
Several factors can contribute to lingering pain or new pain after a root canal procedure, particularly when pressure is applied through biting:
-
Incomplete Treatment: Sometimes, infection may not be entirely eradicated during the initial root canal. Residual bacteria can cause inflammation and pain, especially when pressure is exerted on the tooth. This often requires a retreatment.
-
Cracked Tooth: A pre-existing or newly discovered crack in the tooth can lead to pain, even after a root canal. The crack may extend beyond the treated area, causing discomfort when biting.
-
Overfilling or Underfilling: Improper filling of the root canals can lead to pain. Overfilling can push material into the surrounding tissues, causing irritation and pain. Underfilling can leave bacteria behind, leading to infection and subsequent pain.
-
Temporary Crown Issues: A temporary crown may not fit perfectly, leading to sensitivity and pain, particularly when biting. This is usually a relatively easily fixable issue.
-
Adjacent Tooth Problems: The pain might not actually originate from the root canal treated tooth. Problems with adjacent teeth, such as decay or gum disease, can be misattributed to the recently treated tooth.
-
Sinus Infection: In some cases, particularly with upper molars, pain might radiate from a sinus infection and feel like it’s coming from the tooth itself. This is more likely to be a dull ache rather than sharp pain when biting.
What Should I Do If My Tooth Hurts After a Root Canal When Biting?
If you're experiencing pain after a root canal, especially when biting, it's crucial to contact your dentist immediately. Delaying treatment can worsen the problem. Your dentist will perform a thorough examination to determine the cause of the pain and recommend the appropriate treatment. This may involve:
-
Retreatment: If infection persists, a retreatment might be necessary to clean and refill the root canals.
-
Apicoectomy: In some cases, a surgical procedure called an apicoectomy may be required to remove the infected tissue at the tip of the root.
-
Crown Adjustment: If the temporary crown is causing the pain, adjustments or a permanent crown may be needed.
-
Treatment of adjacent tooth: If the pain originates from a neighbouring tooth, that tooth will need appropriate treatment such as a filling or root canal.
-
Referral to a specialist: Your dentist might refer you to an endodontist (root canal specialist) or oral surgeon for more complex cases.
How Can I Manage the Pain Until I See My Dentist?
While waiting for your appointment, you can take over-the-counter pain relievers such as ibuprofen or acetaminophen to help manage the discomfort. Avoid chewing on the affected side to minimize pressure on the tooth. Gentle rinsing with salt water can also help. Do not attempt to self-treat.
Is It Normal to Have Some Discomfort After a Root Canal?
Some mild discomfort or sensitivity is normal in the days following a root canal. However, severe pain, especially when biting, is not typical and warrants immediate professional attention. Your dentist should be able to provide a timeline of when to expect a lessening of discomfort and when to be concerned.
Can a Tooth Still Fail After a Root Canal?
While root canals are highly successful, there's always a small chance of failure. Several factors can contribute to this, including persistent infection, cracks in the tooth, or inadequate initial treatment.
When Should I See a Dentist After a Root Canal?
You should schedule a follow-up appointment with your dentist as advised. This allows them to monitor your healing progress and address any concerns. Don't wait for severe pain to develop before seeking professional attention. Proactive care is essential for maintaining the health and longevity of your tooth after root canal treatment.
