Assuming it is the common type (Sears used to market a self sharpening one) You can sharpen it until the teeth are completely gone. Maybe 30 times, I never counted. This is a skill one needs to develop/learn if they want to save money on cutting wood. It takes practice to get good at it. Getting it done professionally is costly and you need to be able to do it yourself when afield. Follow the instructions in your owners manual. You need the correct size file. You must use the proper angle. Always work forward only, lifting the file on the backstroke. File until the chromium plating on top of the tooth starts to flake (that's what it is there for, to show you where the good edge is.) That's usually only 3-4 strokes. Remember to keep teeth away from dirt. touch dirt once and edge is gone, really! When the oil starts to burn on a dull chain it will make dark spots on top of the teeth. Novice loggers have their saws cutting crooked, this is because they do one side well and get the angle wrong on the other side. You must do one side from left and one side from right. You can buy sharpening guides but I never used one. Too hard to carry into woods. File the rakers (depth gauges) every 2-3 sharpenings as well. I hope this isn't more info than you needed.

A chain saw chain can be sharpened as often as needed until the
teeth wear down. Then a new chain has to be put on.

You have carrier teeth and cutting teeth. If either of those are gone then you are done. This is several times. It is something you can do with a lot of practice. Go pay a saw shop the $3 to sharpen it. If you buy your saw from a dealer, they will usually sharpen it no charge.

it is all dependent upon whether or not you know how to sharpen a saw. I touch the blade with a file after about 15 or so cuts, but I don't file it to nothing. Depending upon your blade type, you may need both a round file and a flat file, ask your chain saw store.

about three or four times usually by then it is worn down enough not to be safe. It never gets sharpened even either so eventually it will cut in circles.
