What could this be? Lump on papilla

.
Its been three days already since i noticed the gums underneath my two front teeth is swollen and theres a bump in it
Is there any home remedy for this?
I tried googling the symptoms i got and it says nasopalatine duct cyst.
I hope its not
Attach is the picture of gums behind two front teeth.

They look like crowns. Are they new? Do you have Xrays after they were placed?
My initial guess is margins that are too deep, or poorly fitting margins.
It's not a nasopalatine cyst.
