Could a probiotic toothpaste help diabetics fight gum disease and lower blood sugar?
NCT ID NCT07069166
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a special toothpaste and mouthwash containing natural 'para-probiotics' can improve gum health and help control blood sugar in people with type 2 diabetes. Forty adults with gum disease and diabetes will use either the para-probiotic products or a standard antiseptic rinse after dental cleaning. Researchers will measure gum healing and blood sugar levels over six months to see if the natural option works as well or better than the standard treatment.
