I understand that improper food handling piror to the canning process can allow bacteria to thrive once sealed, and that if a food container is punctured then of course any nasties can seep in due to there no longer being a barrier – but why does a deep dent also seem to carry as much risk as the can actually being punctured? Never understood this.

Bulging cans are a sign of botulism (insanely rare these days, so the whole question may be moot). If a can is dented, even though otherwise intact, it may conceal the tell-tale bulging.
