The vestibular lamina is responsible for the formation of the vestibule (the space bordered by the junction of the gingiva and the tissue of the inner cheek) and arises from a group of cells called the primary epithelial band. This band is created at about 37 days of development in utero. The vestibular lamina forms shortly after the dental lamina and is positioned right in front of it. The vestibule is formed by the proliferation of the vestibular lamina into the ectomesenchyme.
