Good bacteria vs. bad breath: probiotics show promise for brace wearers

This study tested whether taking oral probiotics (good bacteria) can improve oral hygiene and reduce bad breath in 120 people wearing braces or clear aligners. Participants were randomly assigned to receive probiotics or a placebo, and researchers measured plaque, gum health, and breath odor. The goal was to see if probiotics could help manage common problems like plaque buildup and halitosis during orthodontic treatment.
