Dentist Tip: Brushing three times a day is ideal. If you can brush once after every mealâbreakfast, lunch, and dinnerâyou minimize the growth of bacteria in your mouth. But wait an hour after each meal: brushing too soon can cause damage to the enamel of your teeth.
My doctor and and lab have never told me I couldn't brush my teeth before fasting. I doubt toothpaste or mouthwash would have any effect. These are not ingested after all and there is no sugar in those products anyway. So brush your teeth, rinse, drink water before you take your fasting blood sugar in the morning. And make sure you wash your hands.
