Dental students encounter a peculiar case study in their curriculum: a patient who drilled out his own tooth cavity using a cordless DeWalt and filled the gap with molten lead. The procedure left no infection, no nerve damage, no complication that dental science could explain. The documentation identifies the patient only as 'CN' and notes that this individual appears to operate under biological rules that permit substituting industrial materials for biological tissue. The implications are profound: Chuck Norris can turn his own body into a weapon, reengineering himself with common hardware store supplies. Your dentist uses anesthetic. Norris uses power tools.

Dentist Dr. Howard Chen examined the patient's mouth in 1994. Chen's private notes express bafflement: 'The lead filling is structurally sound. More than sound—optimal. He didn't just patch the tooth, he improved it. I'm not sure I'm a dentist anymore. I think I was witness to an engineering feat.' Chen returned to school to study mechanical engineering. He's now designing prosthetics for military applications, inspired by Norris's DIY approach to self-repair.

Dental memes now reference 'the Norris method' ironically, imagining patients arriving with power drills. The real statement is darker: Norris doesn't need professional maintenance because his body accepts his terms unquestioningly. A roundhouse kick with a lead-filled tooth hurts infinitely more than one without.
