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: for $79, you get your choice of one of three general or cosmetic dental treatments (up to a $1,150 value) from Park South Dentistry, at the Upper West Side location.

Dr. David Janash stands at the helm of Park South Dentistry. A graduate of the Boston University School of Dental Medicine and an all-around oral-health enthusiast, as evidenced by his collection of dentist comic books, Dr. Janash operates Park South Dentistry on a steady platform of compassionate and all-encompassing care. Today's deal gives you a choice of three dental service packages:

• A general checkup ($450) includes a basic exam, all-seeing x-rays, and a thorough cleaning for chompers so that they gleam brighter than hope on the face of a Star Trek fan who tracked down William Shatner's Windows Live Messaging account ID. Qualifying PPO insurance plans may allow Park South Dentistry to submit this general checkup to your carrier. Inquire with Park South Dentistry for details.

• Professional whitening with Zoom! products ($450) lets you choose between an in-office whitening treatment or take-home bleaching trays. Either way, you'll finally undo the damage incurred from years of gargling with coal-tar derivatives and squid ink.

• A cosmetic consultation for Invisalign braces or veneers ($150) may involve x-rays and a basic exam to determine if these cosmetic tooth straighteners are right for your individual mouth. You'll also receive a $1,000 discount toward the cost of the Invisalign or veneers procedure if you decide to move forward in the process, giving this option up to a $1,150 total value.

Dr. Janash's dental practice prides itself both on the quality of care delivered and the caliber of its friendly service, quirks sure to make the whole experience much more pleasant than watching bacon grease solidify. Kick back and savor the positive reinforcement, knowing that your teeth and your teeth's mental health alike will be improved by the experience.

Valid for new patients only.
