Our formula is a thick gel that has a higher percentage of active dentistry tooth bleaching ingredients than most other teeth whitening products. At home teeth whitening is the same professional strength product that dentists sell for $300-$600. Yet we charge you less than 10% of that for the same white smile. Keeping your teeth white is like good housekeeping; teeth whitening needs to be touched up or cleaned once a week to once a month depending on your oral care.
