Hello there ,
Thanks for writing your query,
Extraction of wisdom 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.
As you have mentioned your right side is healing and left side of the jaw is oozing brown discharge , i suspect there is infection in the extraction wound on left side with abscess
i would suggest you to get the abscess drained and socket curretted . 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,
