Can you show your smile with a selfie?

A selfie is one of the easiest ways to show off your smile. While it's tempting to take a selfie at any time, certain lighting is most effective. It's best to take a selfie in front of a window with a bright light source. Make sure your face is clearly distinguished against a soft white background with no shadows. Take a look at yourself—is your smile as wide as possible while still looking natural? If not, you may need more time in the mirror!
