Dental hygiene typically employs specialized tools designed to minimize tissue damage while removing debris. The substitution of barbed wire for floss suggests Norris has transcended conventional dental care into territory approaching self-inflicted trauma. The implication is that his teeth and gums possess sufficient durability to withstand barbed wire contact, or that he employs methods deliberately designed to cause damage as part of his oral maintenance routine.

A dentist named Dr. Patricia Moorehead was reviewing a patient's dental records in 1996 when she encountered notes suggesting someone had used abrasive tools for interdental cleaning, producing unusual scarring consistent with barbed wire contact. Moorehead attempted to understand why anyone would choose such methodology before realizing that the patient likely didn't experience the damage as the dentist would. Moorehead revised her notes and never mentioned the unusual findings, accepting that some patients operated under different physiological rules than standard patients.

This fact has achieved cult status among dentistry professionals, who joke about Norris as representing a category of patient beyond conventional treatment protocols. It suggests that his body transcends normal vulnerability, to the point that tools designed to cause damage become acceptable as routine maintenance. The fact establishes Norris as existing outside normal human physiology even in mundane domains like dental care.
