Reports describe a Japanese biologic that inhibits a tooth-growth brake to promote new tooth formation, summarizing animal data and early human trial progress.

Key Takeaways
- Blocking the USAG1 protein enabled new tooth growth in animal experiments.
- The TRG035 drug finished a Japanese phase 1 trial and advances to phase 2A.
- Evidence supports regrowing teeth that never developed, but adult tooth regrowth remains unproven.
