Dental questions in Frank Norris's novel "McTeague"

Frank Norris's McTeague, one of the first novels in which the main character is a dentist and dentistry is central to the plot, has been a minor member of the American literary canon for over a century. Possibly because Norris was such a committed and practicing realist/naturalist, his characterization of McTeague as a believable dentist has not until now been questioned. Nor has his use or misuse of the California Dental Licensure Legislation of 1885 to bring about McTeague's downfall been subjected to historical analysis. Such analysis may cast doubt on the credibility and reputation of the novel.
