teeth on a cog or chainring will all wear at roughly the same rate
the sharp ones you see come like that from the factory to aid shifting
these are called gates
look closely at adjacent teeth to the sharp ones
and you will see pins on the chainrings and three dimensional sides on the cogs
these are called ramps
also
generally speaking
chains are the first component to begin wearing
and when they wear the distance between the pins increases
then the worn chain causes more wear on the cogs
the chainrings
especially the larger ones
take much longer to wear than cogs
