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.
To me, I need at least 30 minutes after brushing my teeth for my sense of taste to return to normal, otherwise everything tastes like toothpaste.
