Obstructed teeth are not necessarily wisdom teeth. Obstructed teeth are teeth that are obstructed by the surrounding soft and hard tissues and cannot erupt smoothly, commonly found in the lateral incisors, premolars, cuspids and wisdom teeth. Due to the limited growth space of the jawbone, the eruption of wisdom teeth is also obstructed by the ascending jaw, which can produce partial or complete obstruction. Wisdom teeth are more likely to be obstructed, which often leads to the misconception that the obstructed tooth is a wisdom tooth. As long as the blocked tooth does not interfere with adjacent teeth and there is no risk of cyst formation or tumor production, it can be removed. If the obstructed tooth has a normal morphology and the adjacent teeth are missing, the alveolar bone can also be removed and the obstructed tooth can be tracted into the dentition to perform chewing functions.
