New York Zoom teeth whitening is a popular and widely used process to whiten teeth. Teeth can discolor with age, as well as from drinking beverages such as coffee, tea, cola, and red wine and smoking. The Zoom system uses hydrogen peroxide solution; the process is accelerated with a special light source. The light breaks down the hydrogen peroxide; oxygen penetrates the tooth enamel and bleaches the stained dentin. There is no change to the teeth, nor is there any risk to the patient.
