Abstract
The natal teeth are defined as the presence of teeth in oral cavity at birth, whereas those that erupt within the neonatal period are called neonatal teeth. The natal or neonatal teeth may cause problems in feeding, risk of aspiration or swallowing and irritation of infant's sublingual frenum.
Very rare complication following extraction or spontaneous exfoliation of natal/neonatal teeth is continuous dentin and cementum formation by the remaining dental papilla and epithelial Hertwig's sheath. This condition is connected with eruption of "tooth-like structure".
The term "residual natal/neonatal tooth" for this clinical situation was suggested.
