I've had very good luck raising dents by using an 80W chisel tip soldering iron. Just put a fairly damp terrycloth rag over the dent and apply the iron. That keeps the steam local to it. If it's badly crushed, then a grain filler as mentioned earlier may keep the dye from over-darkening the crushed grains.

If you have a moisture problem where you are, you can seal the whole stock into a polyethylene bag with some desiccant for a couple of weeks before you apply the first coat of finish.

As already mentioned, Flexner comments that items called Tung Oil Finishes merely look like tung nut oil finishes, but often contain no tung oil themselves. You can add driers to tung oil. Again. Flexner walks you through all that.
