As someone who has experienced decades of poverty and chronic depression who is now finally in a more stable place, I'd be willing to trade certain other body parts if it meant I could have a do over on my teeth. As long as the pain isn't life long, I'd get over it.

I'm self conscious about the way my mouth moves when I talk, how I smile or laugh (whether or not it's worth the risk) and even how I chew. I'd be willing to be a test subject, because God knows what they'd charge if it works.
