Once or twice. I brush them after breakfast and then later on in the day if I'm going out somewhere or if someone is coming over.

If someone else is sleeping near me I brush them before bed too, which makes two or three times.

I brush in the morning and I have to brush my teeth at night or I can't go to sleep.

Then if I am going out to meet someone, especially the one I kiss , then I will brush my teeth.

So that is a minimum of twice a day.

I brush in the morning, Night and if im going out or going to work.
So three times a day sometimes.

I cant stand the feeling of un cleaness..
Also **** up teeth.

I don't brush my as often as i should, if i was going out everyday i would brush them everyday though.

I usually brush my teeth at least once every day.

I'm with Derr, I don't do it as much as I should. I brush em' everytime I get out of the shower, but if I'm being lazy and don't take a shower and leave the house I might skip.

So after shower, and if I'm leaving house and I've ate something nasty since shower.
