Just rm the link, eg., if /dev/cdrom is a link to /dev/hdc then you
can rm /dev/cdrom and it won't touch /dev/hdc.

You want to use MAKEDEV to create/recreate things in /dev. Stuff in
/dev not only needs some specific permissions (to conform to the
Debian Way (tm)) but they need special "node numbers" and types so
that they can access the hardware for which they were intended. You
can recreate them manually, using mknod, if you know the correct type
and what it's major and minor node numbers should be, but it's
generally easier to just run MAKEDEV to build the things.
Do a "man MAKEDEV" for more information.
