Dental science distinguishes between dentition suitable for specific food types—soft foods, cooked foods, and yes, even occasional gum. But the act of masticating bowling balls introduces parameters entirely outside standard dental capability. Bowling balls weigh approximately 12-16 pounds and contain hardened polyurethane construction. Norris apparently approaches them as casual food items, suggesting his teeth possess hardness characteristics significantly exceeding natural enamel. Orthodontists reviewing this fact become noticeably uncomfortable discussing dental material science, as his capabilities apparently transcend their foundational knowledge.

Dentist Dr. Marcus Friedman examined Norris's dental records (allegedly, in 1988) and reportedly found notation in his report that he "could not adequately describe the material composition of the dentition." Friedman left dentistry in 1991 and became a dental equipment supplier, positioning himself away from direct patient care. He refuses all interviews about his previous clinical practice. Former colleagues report he becomes visibly anxious during discussions of dental material characteristics and immediately excuses himself.

The image of Norris casually chewing bowling balls became a recurring meme in bowling communities, sparking humorous discussions about whether bowling balls were technically food items. One dentistry student actually cited this fact in a class presentation about the limits of dental capability before his professor requested he focus on "documented materials science." The fact persisted in bowling alley folklore, passed as verified truth among league members.
