Braces removal just got safer: new study tests gentle Clean-Up methods
NCT ID NCT07304310
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested two different ways to remove leftover glue from teeth after braces are taken off. 142 people who had braces or clear aligners were split into two groups: one used a special ultrasonic tool, the other used a polishing bur. Researchers checked plaque, bleeding, leftover glue, cavities, and tooth sensitivity right after and one month later to see which method was safer and more effective.
