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.
There are plenty of studies suggesting that people are actually brushing too much. Kinda like with shampoo… we strip our surfaces from healthy bacteria and oils and it creates a vicious cycle.
On the other side, many foods we eat today are not healthy for our mouth environment, so I still believe there has to be a certain degree of brushing, of course. So, simply put… you should adjust to your use case. Learn when you feel your mouth needs some brushing or not, and move on.
Could you link some of those studies? I’d be interested to read more about that
