When the Inner Parts of the Human Body Become Najis
Issue No.235- The inner parts of the human body (like the inside of the mouth or nose), become ṭāhir after the removal of a najāsah. Hence, if gums bleed and the blood disappears in saliva or he spits the blood out rinsing the mouth will not be necessary. Therefore, in general if something comes into contact with a najāsah in someone's inner parts it does not become najis. However, if artificial teeth become najis they should be rinsed, as a recommended precaution.
