Thanks for asking the query,
White spots and projections around gum and tongue can be salivary gland swelling , cystic lesion like ranula
or some kind of infection arrising from adjacent tooth or jaw bone .
Oral cancers are caused due to chronic use of tobocco chewing, tobacco smoking
, betel nut chewing , intake of hot spicy foods, long standing trauma, ulcerations infections may develop into malignancies this can be confirmed by clinical evaluation.
Exact diagnosis can be made on visual examination of the area and pathological test .
You also require an OPG to confirm the lesion.
I would suggest you to get the candition examined by the Oral and Maxillofacial Surgeon .
Hope this helps out.
