Pain after a root canal treatment
When you have a condition that requires endodontic treatment, you will already have some degree of irritation of the dental and periodontal tissues. The root canal procedure itself can also cause some irritation. Therefore some root canal pain after the procedure, usually a mild dull pain, is quite common and certainly not alarming. Most patients experience a tender tooth for the first days after treatment.
Causes of Post Root Canal Pain
If the pain after root canal is intense, this could be a sign of complications and possibly of a root canal failure. In about one percent of the cases further treatment or even tooth extraction may be required to relieve the root canal pain.
If you wonder how it is possible for the tooth to hurt after the tooth nerves have been removed, you should know that it is usually the periodontal tissues that cause the post root canal pain and not the treated tooth. The only exception is in cases of failed root canals when the tooth hurts because the nerves are not successfully removed.
As a general rule, the more painful a tooth was before treatment, the more likely it is that you will experience a stronger tooth pain after the root canal therapy. The most common causes of post root canal pain include:
Remedies for Root Canal Pain Relief
The normal post root canal pain can be relieved by taking an over-the-counter pain reliever, usually an anti-inflammatory medicine like Ibuprofen. Sometimes an antibiotic is also prescribed to minimize the risk of a new infection.
Occlusion problems should be corrected by reducing the treated tooth as soon as possible to prevent further inflammation of the tooth that could lead to more complications.
If there are signs of infection antibiotics will be prescribed. If an abscess is formed, post root canal pain can be relieved temporarily by providing drainage, but the treatment will more probably have to be repeated.
In case of a failed root canal pain, a re-treatment and possibly an apicoectomy are needed in order to save the tooth. If neither proves to be successful a tooth extraction is necessary. A stronger prescription pain medicine may be needed for post root canal pain relief until the tooth is re-treated or extracted.
Prevention of Pain after Root Canal Treatment
The root canal therapy may require several appointments until it is completed. The tooth can not be filled before the infection is fully eliminated. Under certain conditions you may have to deal with some amount of root canal pain between the dental appointments:
