when I was 10 I stoped brushing my teeth and only started again when I was twenty

Usually when I remember, but I tend to be very forgetful.
It can range from once a week to once a day.

Never. I don't have any.

3 times

1. Before going to work.
2. After Lunch
3. Before sleep

Are you assuming my dental identity?

Once a day either morning or night. The other time is using mouth wash.

"How often do you brush, Ralph?"
"Three times a day, sir."
"Why must you turn my office into a House of Lies!?"
"You're right. I don't brush. sob I don't brush!"
"Let's look at a picture book: The Big Book of British Smiles."
"sob That's enough!! sob That's enough! sob"

I brushed once, it was fun.

Thrice daily

My teeth aren't long enough to brush. I just comb them.

Depends.. I always bush in the morning and before bed; if I'm going out I'll usually brush first then also.

only eat twice a day so brushing my teeth 3 times doesn't make much sense.

I brush my teeth once a month, whether I need it or not.

Meh. Usually once a day, but sometimes twice. As someone who drinks coffee for the first couple hours of being awake and doesn't really eat much of a breakfast, hard to find a good time to brush in the morning.
Brushing twice a day is of course the most ideal... but to those who only brush once daily: at least brush at nighttime. I remember a dentist once told me, that brushing before bed is very important. Has something to do with the way that food and other gunk sticks to your teeth while you're sleeping, or something, I can't exactly remember his explanation.

I dont have teeths.

The day before and on the day I need to go to the dentist for check-up... so 2 or 4 times per year.
...I'm a very lazy person. (And, honestly, lately I can't make myself care anymore...)

Do you have to brush dentures? If yes... why?

Right away in the morning, sometimes during the day, if I'm going out or feel like it for some reason, and before bed. Also floss before bed - you should do that cause food gets stuck between your teeth and that shit aint good if you wanna keep 'em healthy.

Twice a day. Isn't this the best option? o.O

come on people, at least once a day is mandatory, not to mention whenever you go out to see somebody, that's a +1 brush

why do U waste your time washing your teeth more than once a day?

hmmm 2 or 3 times depending if i wake up in the morning or nah
after breakfast, after lunch and after dinner
