Good on you for bringing it up! Haha. Yeah, I always do. I'm not sure if I bear the 'save the planet' idea in mind though - I just tend to do it every time I brush my teeth, probably as a habit. But that's also partly because my teeth-brushing patterns are becoming slightly odd, so when I do brush them I make sure I do for a while. I'm not one of those people who brushes their teeth obsessively, or anything.
