Chainring worn ???

Was just indexing my gears and discovered that some of the teeth on the outer chainring look to be worn a lot worse than others. Only have 5-6 hundred miles done on the bike. Is this normal that they should be so uneven or what could be causing it to happen. Does it really matter???
Thanks

You should be able to go through a number of chains before the chainrings need replacing. At least this is the case if you replace each chain before it has stretched too much.
The "worn" teeth may not actually be worn. All the teeth wear together at the same rate.
Some teeth are smaller than others when new. This is to help with shifting from one chainring to another.0 -

I always wondered why that was! :oops:0 -
5-6 hundred miles doesn't sound right. I just changed my chainring and the old one had done just over 10k miles0

Called to my LBS earlier and got a look at a 105 front chainring and it is exactly the same. Seems its the norm, to aid shifting and the "Worn Teeth" are is certain areas which correspond to your pedal stroke. Suppose the idea is that you dont put too much pressure where the "Worn Teeth" are. Kind of makes since.0
