Thanks for asking the query,
can form in any part of jaw and it can quickly expand damaging a lot of jaw bone.
It can be caused by dental injury
, trauma , a build up of plague
and calculus in the mouth due to poor oral hygiene , salivary gland obstructions .
Treatment of cyst depends upon the type of cyst.
Generally it is drainage
of pus from the infected cyst.
I would suggest you to consult Oral and Maxellofacial surgeon , get checkup done.
Take an OPG.
Get an biopsy
done to confirm the diagnosis .
At home maintain a good oral hygiene .
mouthwash gargles twice daily.
Hope this helps out.
