I never understood why people brush their teeth and then go eat breakfast, that makes no sense ... first eat then brush

So the real reason that's not being explained is that our enamel is softer and weaker after a night's sleep.

So, in your mouth, there is bacteria. Even brushing as well as you can, there's a microbiome that's ever-present in your mouth (this is why traditional mouthwashes are so bad - they unbalance ALL bacteria in your mouth, even the good stuff).

This bacteria stays pretty much in balance in a well-taken care-of mouth, as long as there is saliva present. Saliva washes away food particles that bad bacteria feast on, boosting their numbers and creating bad odor. But, more importantly, when bacteria feast on sugar, it turns to acid.

This acid softens our teeth, which is why those with chronic dry-mouth will often suffer cavities more frequently.

When we sleep, saliva production pretty much halts. That's why you wake up with a cottony mouth. If you eat right after waking, you're basically converting any sugar you eat directly into acid that goes to work at your teeth.

By brushing prior to eating, you "restore" your mouth's balance, stimulate saliva, and are ready to eat.

It's actually healthier for the teeth since you clean them without it interacring with the food. No need to brush after meals unless you want to get rid of some smell, and then mouthwash works better.

But then that food sticks between your teeth and festers, no? I know we don't brush after lunch either but still. Idk, just paranoid after having $3000 of cavities/extraction mostly from no flossing I just wanna make sure my teeth are taken care of the best way

Especially if you're going to have OJ with your breakfast! The taste of OJ after brushing your teeth is the worst!
