Invisible wisdom teeth refer to wisdom teeth that are buried and obstructed. This type of wisdom tooth is buried deep in the jawbone and no trace of wisdom tooth can be seen in the mouth. Whether this type of wisdom tooth needs to be removed or not should be analyzed on a case-by-case basis. If the wisdom tooth is growing horizontally or obliquely and is particularly adjacent to the 2nd molar in front, it is recommended to have it removed. In order to avoid such problems, it is recommended to extract this kind of wisdom tooth as soon as possible. However, if the buried wisdom tooth is very deep and is distant from the anterior 2nd molar, and has a particularly close relationship with the inferior alveolar nerve canal, there is a high possibility of damaging the nerve when extracting it. In this case, it can be temporarily observed clinically. However, it is also recommended to take dental radiographs of the wisdom tooth every year to check whether it has a tendency to erupt, or has the power to grow forward, or may form a tooth-containing cyst, and if the wisdom tooth is found to be abnormal, it is recommended to extract it as soon as possible.
