This is something different. This treatment is not for replacing teeth that were somehow lost, but for people where one or more teeth didn't develop in the first place.
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.
If this could eventually replace lost teeth, I'd love it. I've been planning to get an implant, and I know the failure rate is low, but the potential side effects of having a screw right below my sinuses is upsetting.
I know fixing the gap in my mouth is a vanity thing purely to conform to western beauty standards but I look like Patrick Star when I open my mouth
