Your teeth are your mouth's ambassadors, your ticket to nachos, and the only things keeping your tongue in your head. Toughen your nacho ticket with today's Groupon at All City Cosmetic Dental Care in Huntington Station. Choose between the following options:

• For $59, you get a dental exam, cleaning, and set of x-rays (a $202 value).
• For $129, you get a teeth whitening treatment (a $350 value).

All City Cosmetic Dental Care marches through toothy trenches under the experienced generalship of Dr. Boris Yusupov, a graduate of the New York University College of Dentistry. Committed to cutting-edge cleaning technology, Dr. Yusupov and his colleagues constantly forage for new ways to help folks say cheese and consume cheese with confidence. After a tooth whisperer inspects mouths for signs of trouble, a hygienist degunks chompers, snaps four bitewing x-rays, and addresses any concerns, pains, or existential ennui before sending pearly pals packing. Patrons in search of sparkling white smiles can opt for simple and quick whitening procedures. A deft dental wizard will diagnose your half-oval-shaped jaw jewels in order to choose the best whitening option for you. Choices include physician-administered Zoom! and Dash gel treatments, as well as Bleach Bright, a take-home kit that requires patients to apply custom tooth-shaped trays for a few hours every day. All three treatments erase enamel stains, leaving teeth blossoming like milk-white wildflowers planted between two rows of lips.

On Tuesday, Thursday, and Friday, the Long Island office keeps the chairs kicked back from 10 a.m. to the work-friendly hour of 7 p.m. A dental excursion to All City ensures you'll walk out refreshed and surprised by the compliments you get from the people you bite every day.
