Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that a
chronic lump over the gums that has not gone for months and even is not painful can be due to causes like a Bony Torus that occurs due to a nodular over growth over the bone..
If it is associated with an infected or decayed tooth it can also be a
Periapical cyst..
Other causes can be
hematoma formation,
hemangioma or arterio-venous malformation etc..
For confirmation and assessing the severity of its pathogenesis, you need to consult an Oral Physician and get evaluated and a thorough clinical evaluation and investigations like x ray,
biopsy etc can help in diagnosis and treatment can be done accordingly..
In case of bony tours, if it bothers, surgical removal can be done otherwise can be left as it is as it is harmless..
In case of a periapical cyst, treatment of the tooth and removal of cyst can help..
Other causes can be treated as per diagnosis..
Hope this information helps..
Thanks and regards.
