Yes, there are a number of tooth abnormalities relating to development. Anodontia is a complete lack of tooth development, and hypodontia is a lack of some tooth development. Anodontia is rare, most often occurring in a condition called Hypohidrotic ectodermal dysplasia, while hypodontia is one of the most common developmental abnormalities, affecting 3.5-8.0% of the population (not including third molars). The absence of third molars is very common, occurring in 20-23% of the population, followed in prevalence by the second premolar and lateral incisor.

A wisdom tooth, in humans, is any of the usual four third molars. Wisdom teeth usually appear between the ages of 17 and 25.Most adults have four wisdom teeth, but it is possible to have fewer (hypodontia), or more, in which case they are called supernumerary teeth. Wisdom teeth commonly affect other teeth as they develop, becoming impacted or "coming in sideways." They are often extracted when this occurs and YES it does pain.
