Not practical, and darkens teeth if you have any bonding's in the front.
Not practical, and darkens teeth if you have bonding's for a while. No way I could use this every night.<br />I did some studying about toothpaste whiteners and there abrasive ingredients. The fact is it will whiten but less than<br /> most whitening toothpaste. I'd pass on it if I were you.
