NCT ID NCT04914533
First seen Sep 17, 2026 · Last updated Sep 18, 2026 · Updated 1 time
Summary
Researchers are testing whether a low-level laser therapy device called Luminance RED can reduce pain and discomfort from recurrent canker sores. Adults who get canker sores at least once a month use the device at home and report daily pain and how hard it is to eat, drink, and brush their teeth. The study also tracks how many participants choose to keep using the device.
