[|Human|] I had my wisdom teeth removed about 3 years ago, they healed fine. However, several months later the area where the back left wisdom tooth caved in, became very painful, and bled. It went away after a week or 2, but it reoccurres every couple months still. My dentist did X-rays but could not find anything in the gum. What could be causing this?
[|AI|]  Hello and welcome to Chat Doctor forum, i would be glad to answer your query, I would like to inform you that due to food impaction and poor oral hygiene, chances of infection and swelling increases.I cannot assure the cause behind recurrent pain and swelling until checked clinically.I would advise you to see an oral surgeon, get a thorough dental check up done. Until then, warm saline rinses(3-4 times/day) will help in pain relief. Use an antibacterial mouth wash(Betadine), 2 times/day.I hope I answered your query, I wish you good health, take care.
