Simple dental fix may boost smile confidence and ease anxiety
NCT ID NCT07480551
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether closing small gaps (less than 2 mm) between the front teeth using tooth-colored fillings can improve how people feel about their oral health and reduce their fear of the dentist. Forty adults with no prior dental work on those teeth received the treatment in one visit. Their dental anxiety and quality of life were measured before and three months after the procedure using standard questionnaires.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Direct composite resin restoration (tooth-colored filling)
- What this could lead to
- If successful, this could show that a simple, non-invasive dental procedure improves both quality of life and reduces dental anxiety for people with small gaps between their front teeth.
- What could go wrong
- This is a small, single-arm study with only 40 participants and no comparison group, so results may not apply to everyone. The follow-up is only three months, so long-term effects are unknown.
