  I'm looking for information about inherited traits, specifically "congenital
  suppression of the third molar" -- lack of wisdom teeth.

In the Online Mendelian Inheritance in Man, there is the following entry:

194100 WISDOM TEETH, ABSENCE OF

Gruneberg (1936) described a family in which a mother and 4 of 5
children lacked some or all wisdom teeth.  The evidence for simple
dominant inheritance is meager.  Gorlin (1977) stated that in one-
third or more of most populations one or more wisdom teeth are
missing.  Mendelian inheritance is doubtful.

Gorlin, R. J.: Minneapolis: personal communication, 1977.

Gruneberg, H.: Two independent inherited tooth anomalies in one
family. J. Hered. 27: 225-228, 1936.


Hope this is of some use.
