Sound waves vs. tooth pain: can 11-Hz beats soothe orthodontic discomfort?
NCT ID NCT07771920
First seen Aug 19, 2026 · Last updated Aug 19, 2026
Summary
This trial tests whether listening to alpha-frequency binaural beats—a type of auditory stimulation that may promote relaxation—can reduce pain and anxiety after orthodontic separator placement. Participants aged 15-30 with mild crowding will be randomly assigned to either listen to a 5-minute binaural beat audio or rest quietly after the procedure. Pain, anxiety, and painkiller use will be measured at several time points over 48 hours to see if this simple, non-drug approach offers relief.
