According to the brand and Dr. Veytsman,red light technologycan help support soft tissue and gum health.

Dr. Veytsman adds that red light technology has also been shown to help with tooth sensitivity.

This is because the light prompts a chemical reaction that improves blood circulation in the area, she explains.

With better blood circulation, inflammation levels within the mouth are reduced overall.

Simultaneously, the light decreases the amount of bacteria in your mouth keeping your soft tissue and gums healthy.

After just one use, she noticed her teeth were a shade whiter.
