If you have a gap in a copper trail, you can solder over the trail to ensure a good connection.  If you have two trails that are connected and should not be, use a dremel rotary tool to remove the copper connecting the trails.  If a trails is damaged beyond repair, use a dremel rotary tool to remove the trail and replace it with a normal insulated wire.
