The Zoom! in-office whitening system will make your teeth dramatically whiter in less than an hour. The procedure is simple. It begins with a short preparation to cover your lips and gums, leaving only your teeth exposed. The Zoom! clinician then applies the proprietary Zoom! whitening gel, which was designed to be used with a specially designed light. The Zoom! light and gel work together to gently penetrate your teeth, breaking up stains and discoloration. With proper care your smile will sparkle for years.
