Wisdom tooth pericoronitis is an inflammation of the gum tissue around the wisdom tooth and can be acute or chronic. Symptoms of chronic periodontitis are dominated by inflammation, while symptoms of acute periodontitis are dominated by fever and swelling. There are two main types of treatment, including home remedies and surgical treatments. Home remedies mainly control periodontitis by controlling the bacteria in the mouth. Patients can wash around their wisdom teeth with a small-headed toothbrush. This washes away the food debris around the wisdom teeth and prevents the growth of bacteria, so that periodontitis does not occur. In addition, you can rinse your mouth with salt water to kill the bacteria in your mouth and destroy the environment for bacteria to grow. By taking these measures, it will help to reduce the inflammation by reducing the bacterial residue and destroying the environment for the bacteria to live. Surgical treatment will be chosen according to the severity of the disease. If the wisdom tooth pericoronitis causes recurrent and unbearable toothache, the doctor will perform debridement treatment under the analgesic effect of local anesthesia, which is more suitable for wisdom tooth pericoronitis with periodontal abscess formation. In more severe cases, the doctor will advise the patient to remove the wisdom tooth so that the periodontitis will gradually recover with the removal of the affected tooth. If the symptoms of periodontitis are mild, try to choose home remedies, but if periodontitis is accompanied by swelling and fever, seek professional help so that it can be treated promptly.
