Because dental dysmorphias make up a large part of the problems we deal with in our daily practices, it is important that we classify them according to their severity. Accordingly, we should define the relevant concepts of norm, anomaly, dysmorphia, and malformation. Over the years these notions have been viewed in a great variety of ways depending on the epoch and the particular society. It seems that nowadays our concepts, enflamed by a relentless media, are orienting themselves toward a more and more narrow concept of what constitutes normality. Our professional attitude is not immune to this societal problem, and many practitioners are tempted to propose treatment when the need for it is uncertain.
