Researchers have developed an innovative tooth powder that whitens teeth safely while repairing enamel and promoting oral health. Unlike traditional peroxide-based whitening products that can weaken enamel, this experimental powder, called BSCT, is activated by the vibrations of an electric toothbrush. The powder is made by combining strontium and calcium ions with barium titanate, forming a ceramic that generates reactive oxygen species (ROS) only when in motion, targeting stains without causing harm. Laboratory tests on human teeth stained with tea and coffee showed that after four hours of brushing, teeth were visibly whiter, and after 12 hours, they were nearly 50% brighter than teeth brushed with a saline solution. Additionally, the powder promoted enamel and dentin repair through mineral deposition. Animal studies in rats on high-sugar diets showed that daily brushing with the powder rebalanced the oral microbiome, reducing harmful bacteria such as Porphyromonas gingivalis and Staphylococcus aureus, while lowering inflammation. While the powder has not yet been formulated into toothpaste, the findings suggest a promising at-home dental care option that combines effective whitening with protection and repair of teeth, offering a safer alternative to traditional chemical treatments.
