The dating site Match.com conducted a 3-year survey of 5000 single men and women and, surprise… the survey participants’ number one priority when sizing up a potential date? Their teeth.

Helen Fisher, the Rutgers research professor and biological anthropologist who created the survey, saw it coming, “From a Darwinian perspective, good teeth are a real indication of your health – how much you drink, smoke, what you’re eating,” she said.

Benefits of a healthy smile:

• Improves your mood – Smiling lifts your spirits.
• Make it genuine – Don’t fake it! Your date can tell.
• Mean it – If it’s from your heart, they will smile back.
• At ease – How they will feel in response to your smile.
• Comfy – Your smile invites them to relax and talk.
• When a woman smiles, she draws people in more confidently.
• When a man raises his eyebrow and smiles, he wants to meet you.
