Gingival cyst of infant is an odontogenic cyst. It is developmental in nature. It arises from the epithelial remnant of dental lamina called cell rests of Serres. The Gingival cyst may appear within three months of age. Clinically it appears on the maxillary and mandibular ridges, and appears creamish white in color. The cyst usually does not need treatment because it tends to undergo involution and disappears. We present a case report of a solitary gingival cyst observed in a baby age four months.
