Combining the use of the miswak with removing the smell of the mouth for the fasting person

Question:
Honorable Shaykh, may Allah grant you success. You mentioned, may Allah forgive you, that the miswak does not remove the smell of the fasting person's mouth because it emanates from the stomach. Then you mentioned, may Allah preserve you, that it is recommended after waking from sleep, and you explained that it removes the smell of the mouth. How do you reconcile these two statements?

Answer:
Yes, the smell has two causes. The smell that emanates from the teeth has two causes: one is from the residue on the teeth, or from sleep, such as the breath emanating onto the teeth. The second cause is what comes out of the stomach of the fasting person due to its emptiness from food.
