One of the main reasons The Seven didn't have much affect was that Aule had made them (The Dwarves) indomitable to the will of others, therefore negating any purpose Sauron had in trying to enslave them through his control of The One Ring, their greed for hoarding gold indeed brought it's own evils upon the dwarves, Smaug was only one of them.

I am one of the few who think that Saruman did have a Ring, one he created with his knowledge of ring-making. One must remember a few things, he was like Sauron in the beginning a Maia of Aule, he had studied the Lore of Ring Making, but most of all we have the words of Gandalf at The Council of Elrond, ' But I rode to the foot of Orthanc, and came to the stair of Saruman; and there he met me and led me up to his high chamber. He wore a ring on his finger'. Why mention this ring, what purpose is there in it?...later Saruman gets angry and let's slip '....For I am Saruman, the Wise, Saruman the Ring-maker, Saruman of Many Colours' Note the use of capital letters to emphasize the word ring and many colours, the latter is explaned but not the former. It may well be that this ring was even less powerful than the 'lesser rings, only essay's in the craft', yet it may well be the source of the power which Saruman used to gain sway over people, his voice, and Gandalf's worry over Saruman's escape and the one tooth left.
