Laser precision could make gummy smile surgery less painful
NCT ID NCT07649226
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This trial tests two minimally invasive laser techniques for crown lengthening in adults with a gummy smile caused by altered passive eruption. One method uses a flapless laser approach, the other creates a small tunnel under the gum. Both aim to reduce pain and swelling compared to traditional scalpel surgery. Researchers will measure healing through saliva tests and check how well the results hold up over six months.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
laser-assisted crown lengthening procedure
What this could lead to
If successful, this could establish a less painful, minimally invasive laser approach for esthetic crown lengthening, reducing recovery time and improving patient comfort.
What could go wrong
This is a small, early-phase trial with only 45 participants, so results may not apply to everyone. Laser techniques may not provide better long-term stability than traditional surgery.
