In Rigify rigs eyes are supposed to be a separate mesh (if not, select an eye in edit mode and press P to separate it from the rest). Then select the eye, shift select the armature, activate the 30th bone layer, select the MCH-eye bone (the only one which has a little target bone on its tip) and press Ctrl p > Bone.
The same applies to teeth, in this case you can directly parent them to the teeth control bones which are in the layer number 0 (Face bone layer).
