[/INST] 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 relives post extraction pain. follow all the post extraction instructions and rinse the mouth with lukewarm saline or antiseptic mouth rinse. i hope this helps , take care. </s>
