Since wisdom teeth are the last teeth to erupt, when the amount of jawbone is smaller than the amount of teeth or when the teeth are not positioned correctly, they can cause wisdom teeth to become blocked. When an obstructed wisdom tooth does not erupt completely, the crown is often covered by gums, resulting in a blind pocket between the tooth and the gums. This often causes food to become embedded when eating food. When the body’s immunity is low (tiredness, staying up late, etc.), it often leads to inflammation of the gums around the wisdom teeth, resulting in redness, swelling and pain that affects eating, and in severe cases, facial swelling, restricted mouth opening and fever. If the above symptoms occur, first of all, it is recommended to pay attention to oral hygiene, rinse the mouth after meals, eat a light diet in the near future, pay attention to rest and avoid staying up all night, etc.; if the patient’s body resistance is strong, the symptoms will be relieved in a few days. If the symptoms continue to worsen, it is recommended to consult a doctor for examination, perform peri-coronal rinsing, and take oral antibiotics if necessary. If similar symptoms occur repeatedly and the wisdom tooth cannot be fully erupted, it is recommended that the wisdom tooth be extracted after the inflammation subsides.
