Thanks for posting your query.
The bony nodes can be torus palatinus or abscess
arised from periapical or periodontal infection
of any tooth involved.
Please do visit a dentist
and get examination done.
If this is just a growth,no need to worry.
If there is pus and fluid accumulated within the lump,it has to be drained as soon as possible.
Root canal treatment
and curettage is indicated in such conditions.
Take antibiotics -complete course too.
Meanwhile,please do not irritate the area using fingernails/safety pins.
Hope this helps.
