Hi,
i have gone through the information provided by you.
Pain and swelling after extraction occurs due to trauma to the bone and soft tissues.
After extraction one can notice the hole of socket covered with gummy tissues for some days until the wound heals completely,after 30-40 days the area where the extraction had done fills up completely by healthy bony & gum tissues and the hole or
depression is no longer seen.
You have not mentioned that you are taking medications after extraction or not.
After extraction I prescribe my patient antibiotics,anti-inlamatory and pain killer medication which helps in reducing the inflammation and infection of the extraction wound.
you can use mouth wash or warm water ( 1 tbs of salt in a glass of water) to gargle 3-4 times a day.
if the pain is intense and unbearable you should visit your
dentist as it could occur if the blood clot is dislodged from socket leading to the infection of bone which is a very painful condition.
In such case you must visit your dentist and get the wound cleaned and dressed with medication.
Hope you satisfied by the answer.
Take care.
Regards
