Description
Antje Geiken and co-authors piloted in 2025 a wireless device that tracks mouth acidity in saliva and in tooth biofilm for four days straight. Mouth pH steers decay and gum harm, but round-the-clock reads in both spots were not feasible before. Twelve young adults wore the probe-laden device for ninety-six hours. At set points they drank a sugar solution so the team could watch the pH dip and recover.
Sugar cut pH sharply in both spots. Saliva always ran less acidic than biofilm, at rest, at the dip, and after recovery. Day-long levels held steady across the four days. The team calls the method fit for daily-life study and a step toward patient-friendly pH watches.
