Invisalign renounces the need for clunky metal braces, as clients can now be custom-fitted with their own set of transparent, removable aligners nearly imperceptible to the unclothed eye. After an initial one-hour exam with X-rays and photos of back teeth giving bunny ears to front teeth, the dentist can determine if Invisalign is right for your choppers. With 3-D computer graphics mapping the ridges and valleys of your mouthscape, aligners can be calibrated precisely to slowly arrange teeth into proper rows. As each patient's needs vary, the straightening process may require as little as 12 or as many as 48 sets of aligners in a 6-to-15-month period for teeth to straighten up and fly right or up to avoid power lines. The cost of Invisalign and Invisalign Teen is different for each patient, with the average ranging from $3,500–$8,000; today's Groupon gets you $1,000 toward the final tab.
