Hygiene is the most important thing. I brush my teeth after meals and I'm happy with the colour. Wouldn't want them any whiter.
On another note... A Long time ago I went on a date with a lady I met on line. Nice enough but her teeth were filthy and stained. They looked like a factory workers dirty tea cup. I mean they were really bad.
I'm "folliclely" challenged so I use clippers and keep my hair at a number 0...
With a concerned look on her face she asked me, if you let your hair grow would you be bald? I made and excuse and left.
