Pericoronitis and gingivitis are common oral diseases. Pericoronitis refers to inflammation around the crown adjacent to a wisdom tooth, characterized by congestion, swelling, and pain in the periodontal tissues of the pericoronal flap, typically caused by food debris around the crown, leading to bacterial infection. This condition often occurs during the eruption of wisdom teeth, especially when the wisdom teeth are misaligned. Pericoronitis is also a manifestation of periodontitis, while gingivitis is caused by bacterial infection of the gingival tissues resulting in congestion and edema. If gingivitis progresses, it can also develop into periodontitis, leading to serious consequences such as loosening and loss of teeth.
