Pericoronitis is a common condition where the gum tissue surrounding a partially erupted wisdom tooth becomes inflamed and infected. When a tooth only breaks through the gum surface partially, it creates a small flap of tissue. This flap acts as a trap for food particles and bacteria, making the area very difficult to clean with a regular toothbrush. Over time, the trapped debris leads to irritation and a localised infection in the soft tissues.
The symptoms of pericoronitis include swollen, red, and painful gums at the back of the mouth. Patients may also experience a bad taste, unpleasant breath, or difficulty opening their jaw fully. In more severe cases, the swelling can spread to the cheek or neck, and you might feel generally unwell with a fever. This condition is particularly common in young adults whose wisdom teeth are still trying to emerge into a crowded jaw.

To prevent the recurrence of pericoronitis, your dentist might suggest two long-term options. The first is a minor procedure to remove the flap of gum tissue covering the tooth. The second, and more common option if the problem persists, is the removal of the wisdom tooth itself. Regular dental check-ups are essential to monitor these teeth and manage any signs of inflammation before they develop into a more serious or painful infection.
