The possession of teeth is a requisite for most jobs and saves their owners from a hard life working as a gold prospector, gold-prospector character actor, or professional baby. Keep your career options open with today's Groupon: for $27, you get a cleaning (up to an $85 value), exam (up to an $86 value), and x-rays (up to a $119 value; up to a $290 total value) at Smile Generation, plus up to $200 off additional treatments. This Groupon is valid at 17 locations.

Rather than paying to be a part of its referral network, Smile Generation's skilled professionals earn the privilege by building up an impeccable record of friendly high-quality dental care. In turn, Smile Generation equips and trains each office in the latest dental technology. A dental exam checks the mouth's mountain ranges for cavities and crevasses. After x-rays plumb patients' gums for signs of deeper decay, a meticulous cleaning gives the heave-ho to any tartar and plaque buildup, clearing the way for future generations of inevitable meal remnants. Additionally, Groupon customers receive $100 off any dental treatment that costs between $350 and $749 or $200 off any treatment that costs $750 or more.

Smile Generation donates $5 of every Groupon to charity:water, a nonprofit organization devoted to bringing clean, safe drinking water to people in developing nations.

Though Smile Generation sometimes offers a discounted price online, this Groupon still offers the best deal available.
