An ounce of prevention is worth a pound of cure, much to the chagrin of brokers who invested heavily in cure. Get in while prevention's still hot with today's Groupon to Russell H. Masunaga, DDS. Choose from the following options:

For $49, you get an exam package (a $350 value), which includes:
• Dental exam
• Dental cleaning
• X-rays
For $79, you get an Under Armour performance-enhancing mouth guard (a $400 value).
• For $79, you get an at-home teeth-whitening treatment (a $500 value).

Dr. Masunaga and his team keep chompers at their sharpest and whitest through professional dental check-ups, protective mouth-wear, and at-home whitening systems. Gum-bones receive a one-hour dental treatment that starts with a full exam to check teeth and gums for blossoming health problems such as cavities, tooth decay, or crabgrass. Next, a nimble-handed technician scours enamel with specialized tools of grime elimination and then directs jawlines in an x-ray photo shoot that captures shots of bones, joints, and nasal passages. Alternatively, customers can defend their pearl boxes from wayward fastballs and privateer tooth fairies with Under Armour mouth guards, fashioned in diverse colors and contoured to each individual’s unique tooth shape.

Patients looking to brighten incisors can opt for the Pola Day CP professional at-home whitening system. In the first of two visits, teeth stand at attention as Dr. Masunaga examines mouths and takes bite impressions to design custom whitening trays. Three days later, patients receive a take-home set of trays and professional-strength whitening gel, devised to evenly coat teeth and create tints whiter than Snow White’s dandruff. Within a week, teeth-owners can admire smiles up to seven shades brighter.
