How long does the pain last after a root canal?
The answer isn’t the same for everyone, but it typically ranges from two to seven days after the anesthesia wears off. Pain during this period is normal due to mild inflammation of the surrounding tissues or the instruments used during the treatment.
In most cases, the pain begins to gradually subside on the first or second day and disappears completely within a week. If the pain persists or becomes more severe, it may indicate a problem that requires immediate medical attention.
Causes of persistent pain after a root canal filling
Despite removing the infected nerve and cleaning the root canal, pain may persist for several reasons, including:
-
Inflammation of the surrounding tissue: Temporary irritation due to deep canal cleaning.
-
Additional infection: Some bacteria may remain inside the canal and cause ongoing inflammation.
-
High filling: If the filling is not level with adjacent teeth, it may lead to pain when biting or chewing.
-
Gum inflammation: Dental instruments or filling materials may cause temporary gum irritation.
-
Tooth sensitivity: Some individuals experience increased sensitivity after the filling, especially when consuming hot or cold beverages.
When is pain normal and when should it be a concern?
It’s normal to experience mild pain after treatment, especially when chewing or applying pressure on the tooth. This can be managed with over-the-counter pain relievers. However, if the pain is:
-
Severe and does not subside within a few days,
-
Accompanied by swelling or an abscess,
-
Or comes with symptoms such as fever or numbness in the face,
It may indicate a deeper issue, such as persistent root inflammation or a remaining untreated infection.
What to do after a root canal filling?
To help reduce pain and speed up recovery, it’s recommended to:
-
Take pain relievers as directed by your doctor.
-
Use antibiotics if prescribed.
-
Avoid hard or sticky foods for a while.
-
Eat soft and cold foods.
-
Avoid hot and cold drinks for a short period.
-
Brush teeth gently with a soft-bristled toothbrush.
-
Avoid chewing on the treated side.
-
Visit the dentist if the pain persists or new symptoms appear.
Best antibiotic for root canal infections
One of the most effective antibiotics for treating root canal infections is Amoxicillin, especially when combined with Clavulanic Acid. In case of a penicillin allergy, Clindamycin may be prescribed as an effective alternative. Always take antibiotics as directed by your healthcare provider.
