I brush my teeth first thing in the morning when I wake up, before breakfast, to ensure I have the perfect coffee breath for the whole day after breakfast.

I ermm… only brush in the morning, after I had my shower. I know I should brush at least twice and I really wish I had the motivation to do so, but somehow I just find myself in bed without brushing.
But, to make up for it a little, I brush my teeth very meticulously for a minimum of 6 to 8 minutes. I follow intermittent fasting, so my next meal won’t be for another couple of hours.
My dentist is always full of praise during my half yearly checkup so I must be doing something right?

After breakfast than floss+brush before bed. Before breakfast doesn’t make sense to me because you’re brushing twice when you haven’t eaten anything.

After my morning coffee to try and reduce coffee staining teeth

Also 100% recommend water flossers, they’re a game changer cuz I was really bad about flossing normally

I remember reading you shouldn’t do it immediately after breakfast due to acids etc increasing the risk of damaging you teeth with the fairly rough brush.
Something like 40 minutes after breakfast would be ideal. I tend to do it maybe 10-20 minutes after bc i have to get ready 🤷

Brush before bed to keep your teeth, brush after breakfast to keep your friends

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.

Before bed and before breakfast. Bacteria grow in your mouth during your sleep, so it’s best to keep them low when you start sleeping, and kill them again before you swallow them with breakfast.

Following the advice of my dentist, in the morning after finishing my coffee and in the evening before bed.

Before bed 99% of the time. If I’m leaving the house then I’ll brush before I do.

I brush pretty much as soon as I get up and right before I go to bed.

I think ideally you’d brush your teeth after every meal, but that would require having a toothbrush with you at all times and I’m too lazy for that. Brushing twice a day is good enough; once around 10-15 minutes after eating breakfast/ the first meal of the day and right before bed.

I brush in the morning, and rinse or floss after I eat anything. I brush when I get home from work, after supper, and before I go to bed.

I used to just brush in the morning and at night, and have a partial to show for it

Build up of bacteria at night means that if you eat in the morning before brushing there will be more bacteria to break down the food into acid which will break down your teeth.

Ideal is to brush first but also brush after each meal*

*as long as the acidity in your mouth is 5.5pH or less your teeth are being broken down by the acid (which means that brushing would be scrubing them with acid and making it worse) in which case you should wait until your spit (which is a buffer solution) returns your pH to normal. Since most foods are acidic the recommendation is to wait 30 mnutes after eating and then brush. Or you can eat suger free gum right after a meal, this will trick your brain to produce more spit which will return the normal pH faster.

My personal system is like so:

Wake up

Use dental jet floss (water floss)

Brush teeth

After any foods eaten chew gum for 10-30 minutes

Floss

Dental jet (if at home)

If I’m at home and have 30 minutes to wait between mouthwash and brushing then I use mouthwash, wait 30 min then brush, if not then just brushing and if I’m not at home then just mouthwash.

Repeat for as many things as I eat that day.

Before bed:

Floss

Dental jet

Mouthwash

Wait 30 min

Brush

As far as I know, getting cavities is a lot about genetics. I floss and brush after dinner and breakfast and don’t overthink it and I’ve been fine for many decades now.
