Especially on the moulds for the top set of teeth since mavity won't help much there.Do you smoke? Tried whitening toothpaste? eg. Colgate whitening, Beverly Hills whitening stuff..
I presume all of you do actually brush your teeth

I smoke and drink and my teethy areperfectly white. The secret is not using those ****** electric brushes and giving them the good old elbow grease.
(not literal elbow grease mind..)
i agree, i dont understand how the electric ones are better. i mean whats stronger then your own force/power.
Its been proven that only the electric toothbrushes with the counter-rotational movement are better than a manual brush i.e. the braun/oral b toothbrushes.
