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: you get your choice of two dental packages from Prudential Dental at either of its two locations in Back Bay and the Financial District:

• For $49, you get a dental exam, x-rays, teeth cleaning, and optional oral-cancer screening (up to a $512 value)
• For $199, you get a Zoom! whitening session and take-home bleaching trays (a $624 value)

The first option starts with a comprehensive exam ($129) before a basic cleaning ($125) purges teeth of plaque and banishes it to exile on a remote island. In the process, standard bitewing x-rays ($59) will let you marvel at the tiny metropolises contained within each tooth, while a panoramic x-ray ($134) ascertains bone levels and searches for lesions. You can also get a ViziLite oral-cancer screening ($65) as part of your regimen of incisive-incisor care. Once Prudential’s premolar detectives have completed a full investigation, they'll debrief patients with an easy-to-understand State–of–the–Chompers address refreshingly free of dense symbolism or dolphin sounds.

With the second option, Groupon holders can experience the tusk-brightening power of the Zoom! in-office whitening system. As you relax in one of Prudential's comfortable exam chairs, a proprietary light-activated whitening gel and a five-minute fluoride treatment will take aim at pesky tooth stains. In just over an hour, mouth bones typically whiten by an average of eight shades, providing a generous point spread for would-be gamblers. You'll also receive a take-home bleaching kit, including custom trays and whitening gel, to ensure that your pearly whites continue to make oysters jealous.

Prudential Dental's doctors and staff are too approachable and easy-going to boast of their years of dental-hygienic experience, but they have ample qualifications in both general and cosmetic dentistry. Even skittish patients, who’ve watched Marathon Man too many times, will feel comfortable and at ease when they enter Prudential Dental’s stylish, cozy offices. There is no purchase limit, so buy both Groupons and prep your pearlies for the horrors of corn-on-the-cob and baked-bean season.
