I wonder if wands "wear out."  Do the magical cores go "bad" after a while?
Dragon heartstrings and unicorn tail hairs are organic matter.  They must be
specially treated somehow.  In GoF, Ollivander tested the wands for
functionality.  Of course, a wand may suffer a break, or maybe even a
hairline fracture could make it slightly malfunction.  How sensitive are
these wands?  Something tells me we won't find out.
I think they do eventually wear out, but that it's more likely to be the
wood than the core.  In SS, Charlie's old wand looks battered and the
unicorn hair's poking out just a bit.  In second year, the wand becomes
nearly useless after the tip's broken and spellotape isn't enough to fix it.
Any additions or other ideas?  I'm not used to speculating.  I specialize in
canon details.
