What is the typical symptomatic presence of internal resorption of the root canal?

Internal resorption of the root canal primarily occurs within the dentin of the tooth and is often not associated with significant symptoms, especially in the early stages. Many patients may not even be aware that internal resorption is occurring because it can progress without causing pain or discomfort. This asymptomatic nature is a critical feature that makes internal resorption distinct from other forms of dental issues, such as pulpitis or external resorption, which are typically associated with pain and sensitivity.

As a result, the typical presentation of internal resorption can indeed be asymptomatic, allowing the condition to be discovered often incidentally during radiographic examinations rather than through symptomatic complaints from the patient. Understanding this characteristic is essential for dental practitioners when diagnosing and treating various dental conditions. Other presentations, like pain, sensitivity to percussion, or swelling, are more indicative of other dental problems such as pulp necrosis, periodontal disease, or periapical infections.
