Laser zaps away orthodontic pain in small trial
NCT ID NCT07456709
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether low-level laser therapy can reduce pain caused by orthodontic separators (rubber bands placed between teeth before braces). Thirty-one adults received different laser doses on three sides of their mouth and a fake treatment on the fourth side. Pain levels were tracked over 72 hours using a scale from 0 to 100. The goal was to see if laser therapy offers real pain relief compared to placebo.
