Laser zaps bad breath in gum disease study
NCT ID NCT06764342
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether adding a special laser treatment (photodynamic therapy) to standard gum cleaning could reduce bad breath. Forty adults with gum disease and self-reported bad breath received full-mouth scaling plus a laser-activated gel on their tongue and deep gum pockets. The researchers measured sulfur gases and bacteria levels before and after treatment to see if the laser made a difference.
