It is advised to brush your teeth at least twice a day, but when? Just before bed is a gimme because you’re about to lie mostly still for 6+ hours. Best to not leave food particles to fester.
What’s the best time for an earlier brushing? After breakfast? After lunch? After work/school?
Plus, what’s up with TV and movies having breakfast scenes where they get up and head right out the door? Did they already brush and now they’re going to leave food to fester all day? Eww.
Typically, I brush and floss before bed. In the morning, I will rinse my mouth out to get a lot of the bacteria from overnight out of my mouth.
If I have the energy, I will brush about an hour after my morning snack and caffeine.
If I don’t have the energy, I will rinse my mouth out after breakfast.
I find rinsing my mouth out, while not as good as brushing, really helps freshen up my mouth.
