A product developed by Chevy Chase dentists and their family is designed to make having braces a little bit more fun. Bracket Ears are earrings designed to look like braces, complete with interchangeable colors. Dr. Casey Crafton, a dentist who runs Crafton Dental in Columbia with his wife, Dr. Lisa Crafton, said he and his daughters started talking about Bracket Ears more than two years ago. His son Christopher was taking part in a bike ride to raise money for autism advocacy, and his daughters, McKenzie and Gigi, had the idea to create a product that could also raise money for good causes. “Somehow, an earring that looks like braces kind of stuck,” Crafton said. Instead of a gem, the post earrings have brackets that look just like the ones orthodontists put on teeth. Colored rubber bands allow people to change the look. “The plan was to sell it to dental practices, and we figured we’d try to do it that way and then donate a portion of the proceeds to autism [advocacy],” Crafton said.
