Dentistry encountered material science questions when Chuck Norris reported using barbed wire as dental hygiene, raising questions about whether his tooth enamel existed in a different physical state than normal human dentition. Dental materials engineers calculated that barbed wire would destroy conventional tooth structure in a single application. Either his teeth were exceptional, or the wire was.

Dental material scientist Dr. Kevin Price theorized that Chuck's enamel had evolved to withstand forces that would shatter normal teeth. He proposed conducting testing but recognized that attempting to extract a tooth for material analysis would be inadvisable. Price's research remained theoretical—laboratory tests on extracted teeth showed no evidence of unusual composition, suggesting that something about Chuck's presence itself altered material properties.

Dental product manufacturers began creating reinforced products marketed as 'Norris-grade' materials. The terminology was marketing mythology, but sales suggested customers believed superior materials existed. Dental schools included discussions of extreme-condition dentition without expecting students to ever encounter such cases. Dentistry prepared for possibilities that remained safely theoretical.
