      Rules of Dentistry

      Dental Restorations/ Extractions for a Fasting Person
      193. Do dentistry acts, like extractions, root canal therapy, anesthesia, and fillings make fast invalid?
      A: If nothing enters the throat, the fast is valid.

      Bleeding in the Mouth While Fasting
      194. If a person who is fasting bleeds in the mouth, does it invalidate his fast?
       A: Bleeding in the mouth does not void a fast. However, it is obligatory to prevent blood from reaching the throat.
      Blood of Gums and Teeth
      195. In Ramadan month, should I purify/rinse inside my mouth if my gums/mouth bleeds?
      A: It is not permissible to swallow it. It is ruled as breaking fast with ḥarām if one does so on purpose during fast. However, rinsing inside the mouth is not necessary.

      To Doubt Swallowing Gums Blood
      196. My gums often bleed and the blood gets mixed with saliva. At times I am not sure whether the saliva that enters my throat is mixed with blood or not. Please tell me what I am supposed to do to overcome this problem.
       A: If the blood from your gums dissolves in the saliva, then the saliva is pure and can be swallowed. If you are not sure whether the saliva is mixed with blood or not, it can still be swallowed without affecting the fast.
      Using Orthodontic Retainers
      197. While fasting, may I use a movable orthodontic retainer?
        A: There is no objection to it.
