discomfort 6 months after wisdom tooth extraction

Hi, I had my right side wisdom teeth extracted 6 month ago but i still feel soreness and pressure like feeling at the extraction site gum, there is no swelling or NO bleeding or NO gross pain, its just soreness and pressure like feeling which is bothering me, I visited general dentist twice and he told me my gums are healing well and had no idea why i have this feeling. I just wanted to check you is this normal healing process or i should go to oral surgeon for it ? someone told me about loose bones is it possible to have loose bone remnants with no gum swelling ?
