Hello there ,
Thanks for writing your query,
Extraction of tooth often ends with complications like pain and swelling post extraction .
usually it takes 7 to 10 days for the extraction wound to heal and close completely provided if there is no infection .
After extraction antibiotic and analgesic
coverage is must to prevent infection of the extraction site and to promote healing.
i would suggest you to start with a antibiotic and analgesic course consulting your dentist
, which helps in subsiding the swelling and pain.
follow all the post extraction instructions and rinse the mouth with lukewarm saline or antiseptic mouth rinse.
If the swelling ,heaviness and pain do not subside after 2 weeks of extraction you need to get the examination done by a dentist for DRY socket
Since there is mild pain and swelling in your case , i hope it will subside in coming days do not worry.
i hope this helps ,
