Remove sharp or jagged edges in mesh The problematic edges are small, convex, sharp protrusions on a larger concave, smooth surface.  Edge split, smooth, and subdivision modifiers do not achieve the smooth surface I'm looking for.  Is there a way to force edges with larger than, say 290 degrees to become less obtuse?  Note that I describe the edge this way because that is the side of the surface I'll be viewing (not side of the surface with the equivalent acute angle).  Here's an example:



The mostly horizontal lines are where thin, jagged protrude out of the otherwise smooth surface.  Close-up:



Using the Smooth brush in sculpt mode with dynamic topology and Collapse short edge enabled gives (applied on various scales for demonstration):



This is close but is there a way to now make the 'crumpled'-looking surface become more like the other smooth surface?
This topology is so messed up (current Sculpt Mode will do that), it might need a retopology.

Either use a Shrinkwrap Modifier to get a clean result with a new mesh and far less verts (after the rough adjustments, you can enable the modifier to be active during Edit Mode which glues your verts to the surface) or use use the Bsurfaces addon. With it, you can convert Grease Pencil strokes into topology. You need to set the grease pencil to Surface or otherwise the strokes won't connect to the underlying mesh.
