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.
At night before bed, 4 minutes. After flossing them.
I just drink water in the morning, coffee later, and you aren’t supposed to brush right after eating or drinking so I’ve not found another convenient time.
If I could remember to do it, I’m sure after lunch would be ideal, I just can’t reliably remember to.
