Maxillary cysts are a common type of cystic disease in the jaws, and are benign in nature. In the early stages of the disease, there are usually no clinical manifestations, but only low-density images of the corresponding areas can be seen through imaging, and the presence of maxillary cysts is mostly discovered when the patient undergoes dental examination or dental treatment. Sometimes, in the middle stage, maxillary cysts can cause darkening of the corresponding teeth and nerve necrosis. However, it is still not easy to detect clinically until the maxillary cyst grows to a larger size, then the corresponding jawbone part will be enlarged and will feel like a ping-pong ball when it is pressed, and in some cases the cyst will cause loosening of the corresponding teeth.
