Wisdom tooth eruption is accompanied by pain, which can be considered a normal phenomenon. Wisdom tooth eruption is often not enough space, so between the wisdom tooth and the upper gums will form a blind pocket, this blind pocket will be retained food debris, bacteria, etc., food debris and bacteria in the blind pocket of the retention of local inflammation, resulting in the emergence of wisdom teeth accompanied by pain. In addition, when wisdom teeth are obliquely blocked, the gap between the wisdom teeth and the front teeth will also cause food residues to be retained, and at the same time, the wisdom teeth will also destroy the good teeth in front of them, causing pulpitis and other symptoms to occur in the front teeth. Therefore, it is normal for wisdom teeth to erupt with a certain amount of pain. When there is wisdom tooth pericoronitis, we can carry out local rinsing and medication, and after the anti-inflammatory process, we should remove the wisdom tooth that often causes wisdom tooth pericoronitis as soon as possible. If the wisdom tooth is growing obliquely, it may crush the front teeth and form pulpal inflammation and other symptoms, which will cause pain, and in this case, we need to remove the obliquely blocked wisdom tooth as soon as possible. In order to avoid pain when wisdom teeth erupt, we can also check the direction of growth and eruption of wisdom teeth through clinical examination or X-ray, and if the wisdom teeth cannot be retained, they can be extracted earlier as a preventive measure.
