I never brush my teeth in the morning and don't see the point after having done so right before bed.Everything about this post is the exact opposite of what you should be doing lol
It's best to do so after a meal, and if you're only going to do it once a day, let the toothpaste sink in overnight. That's optimal. Worst time is first thing in the morning before eating breakfast since you'll immediately undo what you did; this will lead to tooth decay.
