Hello there ,
Thanks for writing your query,
After 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
follow all the post extraction instructions and rinse the mouth with lukewarm saline or antiseptic mouth rinse.
sharp bony spicules if any can be filed up , plese visit a dentist and get the examination done.
i hope this helps ,
