Pyorrhea is characterize by an inflammation of the gums and membranes that cover the roots of the teeth. More teeth are lost by people over age 35 because of this disease than any other cause. In a German study of 70 patients with pyorrhea of varying stages, after just 5 to 10 treatments with a neem-based toothpaste and mouthwash there was significant improvement.
Bleeding gums had healed and the secretion from pockets around the teeth had stopped. The blue tinted colored gums returned to a healthy pale pink color. Neem bark is more active than the leaves against certain bacteria and is considerably less bitter making it the neem ingredient of choice in toothpastes and mouthwashes.
