I'm gonna disagree with all the "it's ruined" posts. It may not be "the right way" or look 100%, but wood glue and clamps then some wood putty (or even better, Bondo) to smooth out the rough spots will get you 90% of the way there.

If you're good with your putty (try using the edge of a putty knife to continue the fake "grain" lines) and sanding, you may not even be able to tell once it's painted.
