The condition may be because if the eruption of the wisdom teeth. Pericoronitis is a painful inflammation and swelling of the gums around the 3rd molar.
The wisdom teeth are the third set of molar teeth that most people get in their late teens or early 20s. Bacteria can get trapped under gum tissue growth over a partially erupted wisdom tooth causing infection and inflammation. It is advised to get your 3rd molar teeth extracted. However, thorough clinical and radiographic examination (OPG) is necessary for definite diagnosis and treatment.
Next Steps
Please visit a dentist to get definite diagnosis and treatment.
