I had a significant issue with 2 teeth(that have since healed) where I was left with papilla loss leaving 2 wide gaps in the region. I'm aware bonding and Restalyne are 2 other options, perhaps braces. However, I came across this case(similar to mine) on regenerating papilla through fibroblast. Where can I find a doctor who specializes in this technique here in the US? I've tried contacting the site, college and doctors listed in case study to no avail. Thank you.
