Keep using it till it doesn't cut. I've got a slot chaser that has a series of carbide tipped blades and it's pretty easy to check if its thrown one of the carbide tips. Some tile saws use a diamond grit on the cutting edge should be able to tell if its worn off and exposing the edge of the metal disc.
