Susquehanna Dental Arts Uses the Zoom! in office whitening system.  The following is paraphrased from the Zoom! Brochure. 

“The Zoom! In-Office Whitening System is a revolutionary tooth whitening procedure.  It’s safe, effective, and fast.  In just over an hour, your teeth will be dramatically whiter.  Zoom! Whitening is ideal for anyone looking for immediate results.  The convenience of Zoom! in comparison to days of wearing trays and gradual whitening makes it the perfect choice for the busy individual.   

The Zoom whitening procedure is simple and painless.  It begins with a short preparation to isolate your lips and gums.  The Zoom! whitening gel is then applied and activated by a specially designed light.  Teeth typically become at least six to ten shades whiter sometimes more.
