Old vs new
Some obvious wear, but nothing detrimental. The teeth are were the problem is at.
Skewed teeth
The teeth on the old one are clearly smaller and slight skewed. This causes excessive wear on the chain rollers, and that causes excessive wear on the rear sprocket. Change your front sprocket before the teeth get visibly skewed to save a costly chain and rear sprocket replacement.
You can replace your front sprocket yourself for a couple tenners, and half an hour of your time.

Spacely Sprockets, for all your sprocket needs...

My steel rear sprocket hasn't worn out in 10 years, I don't change the front till it's missing teeth...

i think I run a 14 in the front and a 54 in the back. JTF part number? I shall guess a Yamaha? LOL

It might be useful to say what vehicle this even is about.

Change sprockets and chain *as a set*, or you're just throwing good money after bad.

Bike of some sort I'm guessing

I don't see the science behind it. The front and rear see the same amount of force, the rear spins slower, that's it.

There you go. The teeth on the front sprocket get two-three times the wear because the get two-three times the amount of "chain interaction"
waffledick
ahhhhhh science, bitch! nice. I've only ever changed in pairs because the chain and sprockets wear together.

My garage only does the same thing. By the time your rear sprocket is worn, your chain and front sprocket are destroyed too, but (1/2)
MG2R
If you just keep an eye on your front sprocket and change it before the teeth are skewed your chain and rear sprocket will live longer (2/2)
