They should last for many years.

The fine teeth of the files do clog with whatever material you are filing. That might be what you are experiencing. I use a thick/plush piece of carpet to lay guitars on while working on them. I wipe the teeth of the files across the surface of the carpet and find that doing so cleans the material out of their teeth.

The teeth can potentially get gummed up if you are filing uncured glue such as epoxy or CA glue.
