Natal teeth: a sign of fortuity IN BRIEF • The presence of natal and neonatal teeth is within the normal physiological time GENERAL or grave misfortune limit of the eruption pattern. • Cultural views can differ significantly from extremely positive to negative. R. Sothinathan1 and K. Shakib2 • Premature extraction of natal teeth can lead to undesirable consequences such as anterior crowding. • Practitioners, while acknowledging differing perspectives, should act in the main interest of the child. Natal teeth are defined as those present in the mouth at birth. They are uncommon and most frequently occur in the an- terior mandible as a pair of primary incisors. They are usually small and poorly developed with little or no root formation. Only 10% of these teeth are supernumerary. Problems arising are difficulty suckling, severe ulceration of the child’s tongue or the mother’s breast and the risk of aspiration. These situations would warrant extraction. If the natal teeth are firm and asymptomatic, conservative management is indicated. Negative cultural attitudes towards natal teeth demand good parental counselling and vigilant management in relation to child protection.
