I brush my teeth before I go to bed... I have a $100 electric toothbrush.. it's the most expensive thing I own aside from my guitar and my laptop.
Honestly though, I think teeth brushing makes your teeth cleaner looking but actually probably contributes to cavities quicker, since you're scraping your enamel off. I know people who never brush their teeth, who never have teeth problems. I have taken care of my teeth for years and I've had to get like 9 fillings. But I also have bad acid reflux..
