Hi.. Can understand your concern.. As per your complain pain and bleeding from the gums at the site of extraction indicates some or the other forms of infection.. An infection can occur as a result of any remaining piece of tooth left into the socket accidentally during accident.. It can also be due to some foreign body inclusions in the socket leading to foreign body reaction and inflammation leading to pain and bleeding.. It can also occur due to poor oral hygiene and as the site of extraction where initial healing has taken place is a more prone site for infection and due to poor oral hygiene there is more bacterial proliferation in the gums leading to infection and bleeding. I would suggest you to consult a dentist and get evaluated for the exact cause of the pain and bleeding and get treated accordingly.. In case of infection due to left over root piece or foreign body removal of the same followed by antibiotics can help.. In case of infection due to poor oral hygiene maintenance of proper hygiene by using mouthwash, warm saline gargles and and proper brushing can help.. Hope your query is solved..
