Gingival cysts in newborns, also known as pulpal membrane cysts, will usually rupture and disappear on their own and do not require special treatment; if the cysts do not disappear for a long period of time, they may be related to certain diseases and require timely diagnosis and treatment. Gingival cysts in newborns are transient abnormalities of the oral mucosa, manifested as small white or yellow nodules on the gums and alveolar ridge, generally no larger than 2~3mm in size, and generally do not cause discomfort. At this time, close observation can be, this kind of cyst will usually disappear on its own, without special treatment. It is important to note that gingival cysts in newborns need to be differentiated from fetal teeth and newborn teeth, as the occurrence of this disease may be related to family genetics, inflammation of the tissues surrounding the tooth germ, and so on. In the case of fetal or neonatal teeth, they usually do not disappear on their own and require further examination.
