Wisdom teeth, also known as wisdom teeth, are part of the human third molar and usually begin to erupt around the age of 20. The symptoms of wisdom teeth are similar to those of other teeth erupting in the mouth. Wisdom teeth are located at the very back of the tooth bed, near the throat. Before the wisdom teeth begin to erupt, the gums will be partially enlarged and whitish, and when pressed, the crown of the wisdom tooth can be felt under the gums, and then the wisdom tooth will break through the gums, resulting in localized redness, swelling and ulceration of the gums, which will be swollen and itchy at this time. The wisdom tooth will erupt with a very small white tip, which is sometimes unnoticeable. If the wisdom tooth has enough space to grow upright, it will erupt fully into the mouth in about 3-6 months. If there is not enough room for the wisdom tooth to erupt, this type of wisdom tooth is called an impaction and only a portion of the crown is able to erupt into the mouth and is below the level of the occlusal plane, which is sometimes not easy to detect, and it is recommended that this type of wisdom tooth be removed as soon as possible.
