I have a chain saw (one of the ones for pruning trees) and the chain popped off. I went to put it back on but one of the teeth is damaged on the part that slides along the arm of the chain saw. It looks like it is only this single tooth that is causing the chain not to slide into the arm. Is there anything I can do to repair the chain or am I going to have to buy a new one?
One of my dad's words of wisdom to me was "Don't mess around with chainsaws." While he meant be careful when using them, I'd say it applies here. While you could try to repair the chain, if it caused something to bind and caused kickback while sawing, the results could be disastrous.
And new chains are cheap compared to prosthetic limbs- $20-$30. So do yourself a favor, throw the old chain away, and buy a new one.
