I've had ).chronic yellow teeth since I was a little girl.. It's either genetic or I have mild dental fluorosis.  I had my teeth whitened at the dentist about 7 years ago and it was very painful (I have so called sensitive teeth. They did look white afterwards  but it lasted only about 10 days.  I know you're supposed to use the whitener at home, but that's like  hitting myself on the head with a hammer.<br /><br />I was amazed how much this lightened my teeth, plus, they feel and look incredibly clean.  You can run your tongue over  your teeth and tell that there's no plaque there.  It's as if you've been to the dentist.  Plus, it really reduces the sensitivity.
