hello and welcome to hcm forum,
according to the dental history it seems you had a tooth abscess
, following which your dentist
extracted the tooth, but if the area still hurts, then i would advise you to meet a specialist
(oral surgeon), who will click an x-ray and check for a tooth remnant .
now for the tooth which has undergone a root canal treatment
, it seems that either the treatment has not been completed yet or the infection is very severe.
i would have appreciated if you would have attached your tooth x-ray with the query,
i recommend antibacterial mouth rinses(betadine
) twice/day for 1 week.
warm saline rinses will also help.
i hope i answered your query,
i wish you good health.
