Gum gaps no more? injections may erase black triangles
NCT ID NCT06314256
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested two injections—hyaluronic acid gel and platelet-rich fibrin (made from your own blood)—to rebuild the small triangle of gum between teeth, often lost due to gum disease or aging. Thirteen healthy adults with moderate gum loss received both treatments in different areas of their mouth. Researchers measured changes in the black triangle size and asked patients which they preferred.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- hyaluronic acid gel and injectable platelet-rich fibrin (i-PRF)
- What this could lead to
- If successful, this could point toward a non-surgical way to fill in black triangles between teeth, improving smile appearance without surgery.
- What could go wrong
- This is a very small, completed Phase 4 trial with only 13 participants, so results may not apply to everyone. The effects may be temporary and require repeat treatments.
