Remember, smiling is the easiest – and cheapest! – way to convey genuine feelings of happiness, love and amusement.

Psychology research suggests that your grin can help you make better first impressions, look more attractive, feel more confident and appear younger (and what’s better than a free anti-aging trick?). When you add to that the fact that smiling also boasts bona fide health benefits – like lowering your blood pressure, releasing endorphins and boosting your immune system – it’s apparent that this simple action packs a pretty powerful punch.

In an effort to promote this healthy and contagious behavior, Top Dentists launched the “Who Makes You Smile?” contest, hoping to highlight one special aspect of smiling – inspiration. We asked you to upload a photo of yourself and the person in your life who makes you smile, along with a short description, for the chance to win daily, regional, and, of course, the grand prize: an all-expense-paid trip to New York City for a teeth-whitening makeover by top dentist Dr. Robert Rawdin, a photo shoot and a $1,000 American Express gift card.

You showed us your significant others, children, siblings, friends and even your beloved pets – and hopefully found yourself smiling more often as you campaigned for your friends and family to vote for your submission. Congratulations to all of the winners, and thanks for making us smile.
