Hi.. Thanks for the query.. Difficulty or soreness during swallowing post wisdom tooth removal can be most probably due to inflammation in throat as wisdom tooth extraction can cause inflammation in soft tissues in the extraction site and due to close proximity of throat there is inflamed in throat too.. The pain and pressure I m adjacent areas can be radiating pain from wisdom tooth site.. White in the extraction socket is the healing tissue that graphically changes colour from red of blood clot to white and so on as it is helpful in healing of the extraction site.. So if there is pain take painkillers like Ibuprofen, Naproxen etc. Do cool compresses over the weekend.. Follow all other post operative instructions given to you.. If there is no improvement in next one week consult an Oral Surgeon and get evaluated.. Hope this helps.. Regards..
