Post-operative edema, specifically following third molar extraction, commonly manifests within the initial 24 to 72 hours. This physiological response is a direct consequence of the surgical trauma inflicted upon the surrounding tissues. The inflammatory process, triggered by tissue damage, leads to an accumulation of fluid in the affected area, resulting in perceptible swelling.
Understanding the typical timeline for the onset and progression of this post-surgical symptom is crucial for patient education and management. Knowing what to expect allows individuals to adequately prepare for the recovery period, manage discomfort, and recognize deviations from the expected healing trajectory. A preemptive understanding can mitigate anxiety associated with the procedure and improve adherence to post-operative instructions.
