Transporting loads of foodstuffs and sugar snacks over pearly cobblestone mouth roads can result in potholes and bridge problems. Maintain your digestive highway with today's Groupon: for $79, new patients get one of three general or cosmetic dental treatments with Lillian Obucina DDS, PC (up to a $600 value). Located a block away from Millennium Park, Dr. Obucina has been shining teeth and correcting crooked smiles for more than 20 years. Choose one treatment from the following options:

• An initial exam, routine cleaning, and four bitewing x-rays (a $250 value), as well as $50 off any future necessary dental treatment such as fillings, crowns, and bonding.

• Either an in-office POLA teeth-whitening treatment (a $600 value) or an at-home POLA teeth-whitening kit (a $300 value). After a consultation, Dr. Obucina may recommend one procedure over the other depending on a patient's tooth and gum health.

• A Lumineers or Invisalign consultation to improve tooth aesthetics complete with an exam and x-rays (a $150 value). If your teeth are found to be good candidates, then patients will also receive $1,000 toward an Invisalign Treatment ($4,000–$5,000) or toward porcelain veneers or Lumineers ($1,200 each).

Whatever your chosen procedure, Dr. Obucina and her helpful cavity-fighting team of professionals will upgrade chipping chompers, brighten lackluster whites and adjust teeth for proper alignment with neighboring tooth constellations. You can schedule an appointment online or over the phone.
