Probiotics and brushing: a tiny study on gum health in teens with braces ends early
NCT ID NCT04634201
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether taking probiotic tablets (Lactobacillus reuteri) twice a day, along with regular tooth brushing, could reduce gum inflammation in teenagers with braces. Only 3 participants were enrolled before the study was terminated early, so no meaningful results were obtained. The idea was that probiotics might help balance the mouth's bacteria and lower the risk of gingivitis.
