If the gums around the wisdom tooth are swollen and painful, pericoronitis must have occurred. The presence of pericoronitis should be treated with anti-inflammatory therapy to remove the inflammation around the wisdom tooth in a timely manner. Pericoronitis is a very common disease in the oral cavity. As the blocked wisdom tooth forms a blind pocket with the surrounding soft tissues, bacteria can accumulate in the blind zone, making it easy for pericoronitis to occur when the resistance is low. Pericoronitis is characterized by significant swelling and pain, as well as localized interstitial infection, restricted mouth opening, and systemic symptoms. It is important to get anti-inflammatory treatment as soon as possible by taking oral anti-inflammatory drugs such as roxithromycin and metronidazole. You should also go to the hospital for local irrigation treatment, using 3% hydrogen peroxide and saline to alternately irrigate the blind pocket, and then apply iodoglycerin to the blind pocket for anti-inflammation. The wisdom tooth pericoronitis usually heals in three to five days, and when the wisdom tooth is no longer swollen and painful, the obstructed wisdom tooth should be removed as soon as possible, otherwise the wisdom tooth pericoronitis will recur. For wisdom teeth that are blocked, it is important to check them as early as possible and have them removed prophylactically as soon as possible. This can prevent a lot of oral diseases from occurring.
