Electric bristles outperform normal toothbrushes in fighting plaque and gum inflammation

A new toothbrush featuring bristles that produce electricity as they bend has demonstrated promise in reducing plaque and gum inflammation, New Scientist reported. The mechanical forces from brushing recharge the surface of the special bristles. This action triggers the formation of molecules that damage bacterial membranes, fighting harmful bacteria more effectively than existing oral care products. [1]

When tested against conventional toothbrushes, the electric bristle design led to more than double the reduction of plaque, gum inflammation, and bleeding. Nicholas Jakubovics at Newcastle University in the United Kingdom, who was not involved in the study, said that the overall concept is great. [1]

Toothbrush designs have evolved significantly over time. Ancient civilizations used chew sticks made from tree twigs around 3000 BC. Bristle toothbrushes made with hog bristles attached to bone or bamboo handles originated in China during the Tang Dynasty and were further refined during the Ming Dynasty before mass production began in England around 1780.

By using mechanical motion to generate electricity and damage harmful bacterial membranes, the new technology offers an improved physical approach to maintaining oral health and preventing gum disease. [1]
