I found a video where they put small holes in the varnish with a knife, then let it sit wet for a couple of hours, then steam it through a towel, and it worked pretty well on a test dent!
The differences between dents and craters is that dents merely compress the wood, without damaging the fibers, while craters break and destroy fibers. Dents can be repairing by expanding the wood, but craters aren’t fixable.
