Whitening requires half an hour of a patient’s time. Dr. Fox has a unique three step approach. First, we use a bleaching machine. Then we apply liquid calcium to your teeth as a coating and sealant. The liquid calcium technique was invented by Dr. Fox with the advice of a Nobel Prize Winner in Chemistry and the Dean of The Harvard School of Dental Medicine. The last step is to make custom trays for touch up bleaching at home. So that when teeth re-stain over time you can touch them up with a special bleaching agent at your convenience. This three-step approach is a cost-effective way to keep the teeth white over a few years. You'll have a glistening smile that you will want to share with the people and setting in NYC for years to come!
