Thanks for asking the query,
Best method to rule out this is by taking a Dental x-ray which will clearly show the presence of left over tooth particles and its position in the jaw . If present, it can be removed surgically from the jaw bone.
I would suggest you to visit the Dentist
and get the checkup done take an x-ray of the region.
You maintain a good oral hygiene
, avoid food lodgement.
Use antiseptic mouthwash gargles twice daily.
Hope this helps out.
