I think that is a good way to fix it. I a brass instrument,
and all brass instruments have very thin tubes and bells
made of high-copper brass. This is fairly soft and easy to dent.
If this happens you sent it away to the repair man and he solders
a wire to the metal and pulls out the dent, then desolders the wire.
 It comes out like new. (and you can really tell)
I don't think the process is overly expensive.

My 2 cents,
