Looking at a 2000 Trek 520 to use as a commuter as opposed to my road bike. The seller says it has about 2,000 miles on it but states the inner crank gear has about six teeth that are worn down to half their length. I guess this is possible at those miles if the gear is warped or has been ran dirty and not lubed. What do you guys think?
It could be feasible, especially if they are a lot of touring miles in hilly terrain. My 520 is used for commuting 90% of the time. 6,000 total miles so far, but probably only 100 or so miles on the small ring... How much does he want for it? Check everything else for wear too. Are they the original tires?
Could those "worn" teeth simply be the derailing gate teeth?
teeth that are worn down don't lose length (they'll stick out just as far from the center of the bottom bracket) but they will lose width. Jur's question is a very valid one.

You can always put on new chain rings
