Treating Apical Periodontitis
How periapical periodontitis is treated depends in part on what treatments have already been performed and on how advanced the inflammation is. In some cases, a root canal might be all that's needed to minimize the inflammation. If a person has already had a root canal and the inflammation seems to be the result of a persistent infection or a new infection, a procedure called an apicoectomy might be needed. During an apicoectomy, the tip of the tooth's root is surgically removed. Although it is usually a last resort, there may be some instances when the best treatment option is to remove the tooth.
Although it seems as if antibiotics would potentially be helpful when it comes to treating apical periodontitis, there isn't much evidence to demonstrate whether that is the case or not. One review from the Cochrane Database of Systematic Reviews found that there is "very low-quality," insufficient evidence when it comes to determining whether or not systemic antibiotics would help adult patients with apical periodontitis.
Anytime you think something is going on with your teeth, gums or the health of your mouth in general, the best thing you can do is schedule an appointment with your dentist. They can take a look inside your mouth, assess your symptoms and recommend the appropriate next steps.
