Introduction: Usually an anxiously awaited event by all the parents in the first year of a their children life is the emergence of the first tooth in the oral cavity. Tooth eruption at about 6 months of age is a common known milestone which is considered, both in terms of functional and psychological changes in the child’s life, and an emotional event for the parents. Eruption of the first tooth normally occurs around the sixth month of a child’s life. Teeth that erupt prematurely have been postulated as natal teeth or which are seen in the oral cavity at birth, and neonatal teeth, which erupt during the first 30 days of life. The majority of natal teeth belong to the normal series and only small percentages are supernumerary. The most common location for natal and neonatal teeth is the lower central incisors area, and posterior teeth are very rare. The etiology of this anomaly remains unknown or called as multifactorial. Clinically, natal and neonatal teeth can be normal in size and shape, or conical, with enamel hypoplasia and a yellow-brownish coloration Paediatricians Abstract Teeth which are present in the oral cavity at the time of birth are called natal teeth and neonatal teeth are those that erupt during the first 30 days of life. . Natal teeth are more frequent than neonatal teeth. The most common location for natal and neonatal teeth is the region of the lower central incisors, and posterior teeth are extremely rare. Early detection and treatment of these teeth are recommended because they are uncomfortable to the feeding mother and may induce trauma of tongue, dehydration, less nutrients intake by the infant and thus results in growth retardation, the pattern and time of eruption of teeth and their morphology. With this paper Authors tried to give a comprehensive review regarding terminology, etiology, classification, clinical presentation and management of natal and neonatal teeth.
