The Zoom! Whitening Teeth Treatment is a simple, non-invasive whitening system that can brighten teeth by 6 to 10 shades. A clinician will prepare the mouth by covering lips and gums, then apply the proprietary Zoom! whitening gel. In just over an hour, the gel, activated by a special light, penetrates stains caused by drinking coffee, eating food, smoking, and smoking food. After the simple Zoom! procedure, your teeth will be flowing with more white than a baking soda truck falling off Niagara Falls.
