Without a healthy mouth to host them, teeth frequently run away to the circus to seek comfort in buckets of cotton candy and sugary soft drinks. Prevent three-ringed dental rebellion with today's Groupon: for $59, you get a dental cleaning, x-rays, and an exam at Bull Valley Dentistry in McHenry.

Doctors John Dano and Mary Haupers and their smile-saving staff employ their powers of dental foresight with comprehensive preventative care. The 60-minute preventative session begins with a tartar-tackling cleaning that lets floss shimmy freely through newly polished mouth fences. An initial exam will determine teeth health and tattle-tell on any mouthy misbehavior before x-rays take a peek at your smile’s porcelain skeleton.

Evening and weekend hours help busy bites stay healthy, and in-office WiFi and TV entertain guests as they wait to flash smiles at Bull Valley’s hygienists and doctors.
