I had a dented tweeter on my Paradigm Studio 20's. I found that by removing the diaphragm and using a soft Q-tip to gently push the dent out worked pretty well. The problem it that with metal domes, the metal is usually stretched when it is dented. Therefore, I am still replacing the diaphragm with a part from Paradigm ($50). This is the best and cheapest way to fix a tweeter - you do not have to replace the whole tweater either.
Fixing the dent did have a noticeable impact on the high frequency clarity however.
If the dent is not deep, this technique is much safer and effective than tape or vacuuming!
