When I was a teenager I wanted to look like someone other than myself. I hated the space between my two front teeth and begged my parents to get me a retainer to close it up. And although they loved that gap, they understood the fragility of an adolescent girl and gave in.
As it turned out, I wasn't diligent in wearing the thing and at some point I lost it altogether.
Today I can spit a mean water spray through those teeth, and all that space makes flossing a breeze.
