There are no treatments for this and bone are probably necessary.  When you pass puberty the joints in your skull are fused and there is no more growth.  It is likely that you have had this dent your whole life or the dent you are feeling is actually just a prominent suture which fused.  In any case if it's not causing any problems there is no need to do anything about it
