Thanks for using Petco Pet Education Center, formerly Petcoach! Based on the swelling's location, this is possibly due to a tooth root abscess. This is something your veterinarian could check for on an examination and treat if confirmed. This is something that is treated with local therapy including drainage, debridement and antibiotics. Good luck and have a great day!
