What I learned 22/7/12
I was looking up further to the "smelly breath" post re the brushing of teeth during the day and I learned:
We ARE allowed to use toothpaste during the day while fasting as long as the toothpaste and it's taste stay out of the throat.
Also - the fast only breaks from bleeding gums if the blood overwhelms the saliva and gets to the throat. If this does not happen and there is only a little bit of blood, your fast is not affected.
