Brief Answer:
pus discharging sinus tract, fibroma

Detailed Answer:
Thanks for your query. I have gone through your query.
As far as The white bump on the gums is concerned, I have two two possibilities.
it can be because of a pus discharging sinus tract secondary to tooth infection or gum infection.
The other possibility is, it can be a irritational fibroma or frictional keratosi with traumatic ulcer.
Based on your description of the lesion, it is difficult to come to a diagnosis. So if you can send the images of the lesion, i can give a exact diagnosis and treatment plan.
If it is a pus discharging sinus tract, you need to consult a oral physician and take a radiograph to confirm the diagnosis, and the tooth can be treated with RCT.
If it is a fibroma or frictional keratosis with a traumatic ulcer, then you need to get it surgically removed under local anesthesia.
I hope my answer will help you, take care.
if any queries are there then you can reply me back.
