Researchers develop mouthwash-based light activation system to kill bacteria that cause tooth decay

For many people prone to tooth decay, regular brushing is not enough,media new atlas reported. It is for this reason that researchers recently developed a new mouthwash-based system that reportedly uses light to kill the bacteria that cause problems. The Lumoral system will be commercially released later this year and developed by Finnish start-up Koite Health, which was founded by scientists at the University of Alto and the University of Helsinki Hospital.

The idea is that the user must first use the Lumorinse mouthwash in the system for 30 seconds. Even after spitting out the mouthwash, the proprietary photosensitive substance remains bound to the bacterial surface present in the plaque.

More specifically, the substance adheres to the deformed streptococcus bacteria that produce phage plaques, along with the bacteria that cause gingivitis. “Good bacteria” in the mouth are not affected.

The user then places a glowing tooth holder between the teeth and places it there for 10 minutes. During this time, the red light absorbed by the device is absorbed by the substance, triggering a chain reaction that reportedly kills the target bacteria. The braces emit blue light at the same time, which is said to enhance antibacterial effects. Finally, the user brushes his teeth as usual to remove plaque.

Although there is already a clinical device for the use of light to eliminate bacteria that cause tooth decay and gum disease, Lumoral is considered unique because it utilizes two types of light and is designed for home use.
