The in-office whitening treatment begins with a brief dental examination and digital photographs, prior to settling into the tooth-altering Zoom! whitening experience. As you recline in a cushioned chair, the friendly dentist will invite you to don a dapper gum-protective shield. Then, once you’re appropriately attired, she’ll paint a hydrogen-peroxide-powered bleaching agent onto your mouth bones, covering each crevice of the spinach-sullied surface. Next, she’ll position a powerful yet gentle-to-the-touch light onto your teeth to activate and expedite the whitening process. As you sit back, the lights work to whiten and renew your chompers, giving them a near-instantaneous and brilliant glow. The entire process, which typically lasts between one and two hours, leaves teeth anywhere between six and 10 shades whiter.
