My understanding is that every time the metal is bent, it weakens it. That includes removing a dent. So you can't restore any structural integrity. If it's going to fail, removing the dent will just bring it closer to that fatal time.
I believe that the only safe way to remove a dent in a bike tube is by closing off the tube and forcing air into it to push the dent back out, but even that doesn't help structural integrity, still risks total failure, and costs about as much as a replacement frame anyway.
