hello and welcome to hcm forum,
i would be glad to answer your query,
I would like you to know that following extraction the soft tissue
or the gums around the tooth become loose and as a normal healing process they tend to heal the extraction site,therefore it resembles a tissue tag. It will disappear within 7-10 days.
kindly perform warm saline rinses(3-4 times/day) to relieve pain and related symptoms if any,
but if the problem persists beyond 10 days then kindly see your dentist
i hope i answered your query,
i wish you good health,
