How can I re-glue dovetail corners that are crooked?

Phil

I have an antique oak desk. One of its deep main dovetail drawers was glued a little crooked, so it is difficult to push in and out. Out of concern for breaking the wood, how can I carefully remove the glued dovetail corners so I can re-glue it together squarely. Everything, drawer glides, etc., is wood. Thank you
