   It will now only break your fast if it reaches the back of your throat or the stomach since you swallowed the water and paste. Brush your teeth before Suhoor and after Iftar, however if you have bad breath during the day, it is best to follow Prophet Muhammad’s Sunnah and use Miswak instead.

No, according to Majmoo’ Fatawa Ibn ‘Uthaymeen, 20/113, “if the substances mixed with the blood do not include nutrients, but rather cleanse the blood, then this does not break the fast.” Even though he is fasting, he may utilize dialysis in this circumstance. He should consult with the doctors about this.”
