Hello! I'm also fasting for 40 days (today is my third day) and in my opinion I don't think it's necessary.. just brush your teeth several time a day with water. It works for me.. but I do this because I don't want to feel any taste at all. In my previous fast, I used toothpaste and I thought the taste of it was disgusting.
and I know how you feel. I'm also tired all the time and I feel like I don't have any energy. Just wait until we're done fasting, we're going to be so healthy! Good luck, you can do it!
