How do you keep your breath fresh during the fast?
It's not my thread but in the OP's absence I can answer this question.
There is a saying of the Prophet: “By the One in Whose Hand my soul is, the breath of the fasting person is more pleasant with Allah than the smell of musk.”
So people are encouraged not to be self conscious about their breath. I brush my teeth with toothpaste. Some people don't want to put something so strongly flavoured in their mouths while fasting, so they may prefer to brush before dawn.
In the time of the Prophet people used a 'miswak' - a twig from a particular tree that when cut the inner strands are like the bristles of a toothbrush, and it contains a fragrant sap which cleans the teeth. You can buy them in many shops and some people prefer to use this than toothpaste during the fasting day.
Point is, there is no right or wrong so long as the intention is good.
