What’s the point of brushing in the morning (you haven’t ate anything + assuming the previous night’s brush was good)

Question

For example, would it make more sense to brush somewhere in the afternoon like halfway through the day?

Answer 1

Brushing applies a layer of protection thanks to the fluoride in toothpaste. It’s not feasible that last nights brushing lasts that long. It’s why you should brush before breakfast, to prevent acid erosion from coffee and orange juice, rather than brushing after breakfast when the enamel has been weekend by aforementioned liquids.

Also, bacteria loves our mouths and 8 hours open or closed the bacteria is eating and pooping all over our teeth which is why most people have smelly morning breath, so it’s best to scrub all that away.
