Researchers at Seoul National University have developed an experimental microneedle patch designed to stimulate the body’s own dental stem cells, potentially promoting natural tooth repair.
The patch delivers a medication known to influence regenerative pathways involved in dental tissue repair. When applied to the gums, it can activate dormant stem cells in the dental pulp, encouraging the formation of dentin, the hard tissue beneath tooth enamel.
Laboratory and early animal studies suggest this approach may support the repair of damaged tooth structures rather than replacing them with artificial materials such as fillings or implants.
If proven effective in humans, this method could offer:
1. A minimally invasive alternative to conventional dental procedures
2. Repair using the body’s own biological processes
3. Reduced reliance on synthetic materials
Experts note that this technology represents a shift toward regenerative dentistry, which focuses on repairing natural tooth tissue rather than replacing it. While early results are promising, further clinical trials are required to confirm safety, effectiveness, and long-term outcomes before widespread use becomes possible.
