When a wisdom tooth grows under a posterior alveolar tooth, after the tooth is removed, the wisdom tooth erupts without any resistance for an indeterminate amount of time depending on the growth of the tooth germ. If the wisdom tooth develops a cyst or is affected by resistance, it may not erupt.
Normal tooth eruption time is generally two and a half months, when the molar affects the eruption of the wisdom tooth, after the molar is removed, if there is no resistance from bone and soft tissue, the wisdom tooth eruption is generally after the completion of calcification of the tooth germ eruption, the specific time varies from person to person, and it is not possible to accurately determine the time of eruption.
After the removal of the molars, if the wisdom teeth are still affected by the resistance of the bone tissue or thick soft tissue, pericoronitis may occur, and the eruption time will be delayed depending on the amount of resistance. Wisdom teeth may also not erupt if there is a dentigerous cyst.
When the wisdom teeth erupt is related to the individual’s physical and oral conditions, specific recommendations first to the hospital radiography.
