A Japanese research team led by Dr. Katsu Takahashi at Kitano Hospital (Osaka) in collaboration with Kyoto University has launched the world’s first human clinical trial for a drug designed to stimulate natural tooth regrowth. The treatment works by blocking the protein USAG-1, which normally suppresses tooth development. Early safety trials began in adults in 2024, with future plans to test on children with congenital tooth agenesis. The first clinical applications could appear around 2030 if the drug proves safe and effective.
How Does the Tooth Regrowth Drug Work?
The mechanism is both elegant and revolutionary. The protein USAG-1 inhibits signaling pathways (Wnt/BMP) responsible for tooth bud development. By administering a monoclonal antibody that blocks USAG-1, dormant tooth buds can resume development and grow into fully functional teeth. Initial animal studies in 2021 demonstrated successful tooth regrowth in mice with congenital tooth loss.
Current Stage of Human Trials in Japan
- Phase I (Safety Testing): Researchers began human trials on adults missing molars to assess safety before expanding to children with congenital tooth agenesis (hypodontia/anodontia).
- Scientific Leadership: The project is led by Dr. Katsu Takahashi, Chief of Dentistry and Oral Surgery at Kitano Hospital, who has been at the forefront of global media reports on this breakthrough.
- Timeline: If successful, the drug could reach clinical use by 2030, pending positive safety and efficacy outcomes in further trials.
Who Are the First Candidates?
- Children with congenital tooth agenesis: The primary target group once safety in adults is confirmed.
- Adults with missing teeth (future possibility): The potential expansion to adult cases (trauma, decay, gum disease) requires more clinical proof and long-term safety validation.
Tooth Regrowth vs. Modern Dental Implants in Istanbul
Even if tooth regrowth becomes a clinical reality, it will not immediately replace today’s advanced options:
- Tooth Regrowth Drug (future): Offers the possibility of natural teeth with roots and vitality, but requires years (3–5 years for a tooth to fully develop and erupt) and remains experimental.
- Dental Implants (today): Provide fast, reliable solutions with high success rates when combined with CBCT planning, guided surgery, and advanced protocols such as All-on-X.
- Bridges and Prosthetics: Still viable in specific situations, especially with today’s digital dentistry and high-strength ceramics.
Bottom line in Istanbul: While biologic regeneration is promising, dental implants remain the gold standard today—especially with advanced full-arch solutions such as All-on-X.

Frequently Asked Questions about the Tooth Regrowth Drug
Is the drug available now?
No. It is still in early-phase clinical trials, limited to research settings in Japan.
When will it be commercially available?
If trials succeed, researchers hope for clinical use by around 2030.
How long would tooth regrowth take?
Even if effective, a natural tooth could take 3–5 years to fully grow and erupt.
Will this replace implants?
Not in the near future. Implants remain the most reliable and immediate solution. Regrowth may become an additional option later.
