Some tenderness or discomfort can occur after root canal treatment. The amount of discomfort varies between patients and depends on factors such as the condition of the tooth before treatment, inflammation in the tissues surrounding the tooth and the treatment performed.
Mild discomfort may occur for a short period after root canal treatment. Severe, increasing or persistent pain should not simply be assumed to be part of normal recovery.
If you experience discomfort after treatment, follow the individual post-operative instructions provided by your endodontist.
If JCV Endodontics has provided you with individual medication instructions following your treatment, follow those instructions. Otherwise, any over-the-counter pain relief should only be taken in accordance with the directions on the medicine packaging, or as advised by your doctor or pharmacist.
Do not exceed the recommended dose stated on the medicine label or any dose specifically prescribed to you by your treating practitioner.
Tell your endodontist, doctor or pharmacist about any relevant medical conditions and medicines you currently take.
Because suitable pain relief depends on your medical history, current medications and individual circumstances, speak with your doctor or pharmacist before taking any pain-relief medicine — particularly if you have any pre-existing medical conditions, take other medications, or are pregnant or breastfeeding.
Severe pain after root canal treatment should be assessed rather than managed by simply increasing the dose of pain medication.
Contact JCV Endodontics if:
A clinical review can help determine whether the symptoms relate to normal post-treatment inflammation or whether further assessment or treatment is required.
Some local tenderness can occur following treatment, but new, significant or increasing swelling requires attention.
Contact JCV Endodontics promptly if you develop:
Dental infection can cause swelling, pain and fever, and should be assessed by a dental practitioner rather than managed with pain medication alone.
Antibiotics are not routinely required simply because a tooth is painful after root canal treatment.
Whether antibiotics are appropriate depends on the clinical circumstances. Healthdirect notes that antibiotics are generally not used for toothache unless there is visible swelling.
If antibiotics are clinically indicated, your practitioner will determine the appropriate medicine, dose and duration based on your individual circumstances.
Do not take leftover antibiotics or antibiotics prescribed for another person.
Seek urgent dental or medical assessment if you develop significant or rapidly increasing swelling, fever or other symptoms suggesting that an infection may be spreading.
Seek emergency medical attention if swelling causes difficulty breathing or speaking, or involves the eye or neck. Healthdirect advises seeking urgent care if mouth swelling is affecting your breathing.
If you have recently undergone root canal treatment at JCV Endodontics and your pain or swelling is severe, increasing or concerning, contact the practice for advice relevant to your treatment.
