Laser zaps root canal bacteria in new study
NCT ID NCT05959629
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether a special laser (Er,Cr:YSGG) can kill bacteria in root canals better than the standard rinse. 56 adults undergoing root canal treatment had their canals cleaned with either the laser or standard sodium hypochlorite. Researchers measured bacterial levels before and after treatment and also checked pain levels. The study was terminated early, so results are limited.

What this could lead to
If successful, this laser method could become a new option to disinfect root canals, potentially reducing infection and pain after treatment.
