No, not at all. That degree of bow is a nominal curve, in both drawers, and should be easy to reverse, to some extent, using the wetted technique. If it bent one way, it should be able to be bent the other way. If still in doubt, bend it slowly, over time, then allow to dry. At least see what effect that has.
