Developmental dental anomalies are marked deviations from the normal colour, contour, size, number and degree of development of teeth. They are classified according to their abnormalities in number, shape, colour, structure, texture, eruption, exfoliation and position. Many dental anomalies have been considered to be the primary feature of some syndromes. They may be the cause of various dental problems. Careful observation and appropriate investigations are required to diagnose the condition and institute appropriate treatment. A multidisciplinary approach may contribute to the success of the treatment. The treatment not only improves speech and masticatory function, but also has psychological implications that may greatly help in regaining self-confidence.
