Our Mouth Care Devices are Supported by Clinical Science

We’ve invested in multiple clinical studies to quantify the impact of the Luminance RED - CankerClear Device.

In a pilot study evaluating the Luminance RED - CankerClear Device for active canker sore outbreaks, the results demonstrated:

  • The majority of participants reported an overall reduction in pain severity and outbreak duration.
  • Participants experienced pain reduction within 1 day.
  • Outbreak duration was significantly reduced.

Upon evaluation, it was observed that the vast majority of participants in the study reported a notable decrease in the intensity of pain they experienced. In addition to this reduction in pain severity, there was also a concurrent shortening in the duration of their symptomatic periods, suggesting an overall improvement in their condition throughout the course of our observation.
