Pericoronitis usually occurs in individuals aged 17 to 25 years, during the eruption of the third molars, commonly known as wisdom teeth. When these teeth do not fully emerge from the gum line, a flap of gum tissue can partially cover the tooth, creating a space where debris can accumulate.
Poor oral hygiene habits, such as inadequate brushing and flossing, can further contribute to the development of pericoronitis.

Symptoms of pericoronitis:

-The most common symptom of pericoronitis is pain and swelling in the affected area(around teeth, angle of jaw & cheeks)
-The pain can range from mild discomfort to severe throbbing pain, making it difficult to chew or speak.

Other symptoms :
-may include bad breath, a foul taste in the mouth, swollen lymph nodes in the neck, and difficulty opening/ closing the mouth.
-In some cases, pus may be present around the affected tooth.
Swelling of lymph nodes also seen in acute cases with toxic systemic complications such as fever, leukocytes & malaise.
