Bony spicule or tissue growth could be present.
Welcome to the forum,
I would like to tell you that the wound healing
after wisdom tooth extraction
takes 1 month to heal, but complete wound healing takes 3 months.
This area is often difficult to clean and often invites bacterial infection, so i would advise you to gargle after every meal, avoid eating from that side and take lukewarm saline and antiseptic mouthwash rinses.
Also visit to the concerned Dentist
and get an x-ray done of the region probably there could be presence of some bony spicules roughness in the bone or tissue growth which could be easily removed by him.If there is any spicule or roughness in the region it could be trimmed and restitched by your Dentist, any tissue growth can be removed surgically.
Also look for the second molar in the region for presence of any caries food lodgement can also be because of it.
Hope you find this as informative and helpful,
If you have any other queries feel free to ask!
Dr Qazi Ammara.
