That's correct, but I'd rather have a hole inside and the dent gone. Looking at the OP's picture, if he has a twin, I'd think a tech could make a round hole under the bed, massage the metal, then cap the hole under the bed.
If it's a rear queen, the dent is under the "night stand" where a hole saw and cover wouldn't ever be seen.
