You said the hay was not an issue, and as someone above pointed out if she is eating it w/o balls of hay laying around it is propobably not entirely due to teeth. Dropping weight w no clear reason is alarming. And, yes, I have seen it before in a very healthy relatively young horse, but I hesitate to say the reason so as not to put the thought in your mind. It was cancer, but that is only one of hundreds of things that can cause rapid unexplained weight loss. I would get a straight mineral supplement (in addition to a block) such as moorman's or the like.
What did the vet say?
There is just as much horse sense as ever, but the horses have most of it.
