Torus Palatinus is an invagination of bone inside the oral cavity if it is on the palate
it is called torus palatine if it is on the manidular bone it is called torus mandibularis.
Normally it does not harm or interfere in normal oral functions, but if it has started giving symptom like pain, tenderness, redness,etc. the best possible treatment is surgical excision.
I suggest you to visit to your dentist
, get it investigated, and take the treatment.
