Are these tiny white dots on my bread mold?
No it is not mold. They are coarse particles of some kind of grain (often corn meal, but in this case maybe wheat as corn meal is usually yellower). They sometimes sprinkle these on when they bake the bread; Sometimes on the bottom of the loaf (often with French bread) I think to keep the bread from sticking to the pan as it bakes. Also makes the bread look rustic and more "homemade."
