How should inflammation be identified after tooth extraction?

First, examine the condition around the tooth to check for symptoms such as redness, swelling, or warmth; second, assess the sensation in the mouth and the level of pain around the tooth—increased pain may indicate inflammation. Additionally, inspect any wounds near the tooth for signs of pus discharge or foul odor. Furthermore, an X-ray examination may be performed as recommended by a doctor to evaluate the area around the tooth and confirm whether inflammation is present.
