Straightening a crooked smile is a great way to improve confidence, garner self-esteem, and bite into other people's sandwiches without leaving identifying tooth prints. Align teeth into stealth formation with today's Groupon: for $2,799, you get a full Invisalign treatment from Dr. Iyad Bakdach at Rutner Dental in Mountain View (a $6,200 value).

Dr. Iyad Bakdach of Rutner Dental gently corrects crooked chompers with Invisalign straightening treatments, earning recognition as an Invisalign elite provider. After Dr. Bakdach explains the treatment and answers any questions in a preliminary consultation, clients relax as the doctor fits mouths for a set of customized, clear plastic aligners and optional subwoofers. The aligners gradually and comfortably shift teeth toward their proper placement and are worn all day except when eating, brushing, or flossing. Across about 18 appointments over the 9–15 month treatment, patients receive new aligners every two weeks for a total of 20–25 aligners, which can be redeployed later on to rehabilitate chattering teeth pranksters into professional jawline models.
