Soft Tissue Pain

[OldRanchHand]

I had my back molar removed in early August and developed a dry socket. Everything finally healed by the end of the month. However, just last week, I had a piece of hard candy in my mouth and without thinking bit down to break it right on the spot where the molar was removed. It didn't break the skin, but now the soft tissue and gum surrounding the old extraction site is tender and sore. There is no swelling that I can discern. Is this anything that warrants a return trip to the dentist, or is it normal for an extraction site to still be a bit tender when biting something hard several months after the tooth was removed. There is no pain unless something presses the soft tissue where the tooth used to be. Apologies for the long post. Hope I explained myself OK.
