There's a lot to smile about in central Ohio this week.

February is National Children’s Dental Health Month, and Ohio ranks 10th in the nation for best overall dental health. Giving employers even more to smile about, website Wallet Hub ranks Ohio first in the country for fewest missed days of work due to dental problems—a costly problem estimated at $442 billion a year in treatment costs and lost productivity. February is heart month, too. Luckily, a Worthington husband-wife, cardiologist-dentist team combine their expertise to use dental health clues to help predict and prevent potential cardiac issues.

Career women on the rise will find it easier to smile with newfound confidence after attending a Dress for Impact seminar on March 2 at the Fitness Loft. It’s part of a women’s breakfast series sponsored by the Small Business Administration and Women’s Business Centers of Ohio. Wardrobe stylist Sue Kantor will help women create their best first impressions. Hold those smiles and put lessons from the morning wardrobe seminar to the test on the afternoon of March 2 at the New Albany Chamber of Commerce Business Expo & Job Fair.  

Those who’d like to get ahead with an MBA might smile at a new weekend option offered by the Ohio State University Fisher College of Business. It’s just another way colleges and universities are getting creative to attract students in a shrinking higher education market. The weekend MBA option includes free chartered buses with Wi-Fi for students coming from Cleveland, Dayton and Cincinnati.

Linda Logan, executive director of the Greater Columbus Sports Commission, will be smiling and waving in her just-announced role as honorary race director for the 2017 OhioHealth Capital City Half Marathon and 2017 USATF Half Marathon Championships on April 29. Host honors for the USA Track & Field Half Marathon Championships were awarded to Columbus for 2016 and 2017 after Logan pitched the city to the track and field governing body. Runners can also register online for a 5K or quarter marathon.

Two smile-inducing foods are getting together again to keep Columbus babies smiling. Hot Chicken Takeover and Mikey’s Late Night Slice will preview their Hot Mikey’s Takeover pizza in a Tuesday evening fundraiser for the Columbus Diaper Bank. Two seatings are available but the preview party will likely be a sellout.
