eli5: Why is it recommended by dentists to brush your teeth in the morning and not just only at night?

Question

In the morning I scrape my tongue and use mouthwash so it smells clean (to me)

But I haven’t eaten anything yet. So why brush before breakfast.

Answer 1

Brush after breakfast, not before. The “brush before breakfast” theory is based on lab conditions that have little bearing on real life behavior.
