Before modern orthodontics, the only way to straighten teeth invisibly was by hiring 24-hour teams of ghosts with OCD. Straighten smiles without getting spooked with today's Groupon: for $49, you get an initial Invisalign exam, x-rays, and impressions at Moshiri Orthodontics in Springfield (a $320 value). This deal also gets you $750 off the total cost of Invisalign treatment or traditional orthodontics.

Father and son duo Dr. Farhad Moshiri and Dr. "Maz" Moshiri recalibrate uneven food mashers with superior-quality cosmetic and restorative orthodontics for clients in need of smile tweaking or total smile rejuvenation. During the Invisalign exam, patients will receive a comprehensive evaluation of their bite, including x-rays, pictures, tooth impressions, and tooth impersonations for the monthly orthodontic comedy showcase. If desired, clear, virtually undetectable molds will then be constructed to get sneakily shifting chompers back into neat rows.

Though this offer does not cover the cost of Invisalign treatment, patients who continue with the procedure will receive a $750 discount toward full Invisalign treatment (an average cost of $6,400–$7,800) or traditional orthodontic services such as braces (an average cost of $5,800–$7,200).
