A primary tooth is considered persistent/over-retained if the last eruption time of the permanent successor tooth had been expired for more than one year and if the primary teeth did not exfoliated yet. The most common type of persistent primary teeth seen on the dental arch was mandibular primary second molars, followed by maxillary primary canines. The following manuscript presents a rare occurrence of sixteen such teeth in both maxillary and mandibular arches of an adult aged 17 years.
