The Dr. Collins Perio Toothbrush is unlike any other toothbrush on the market. With its innovative, patented tapering technique, the Perio Toothbrush features super slim polyester bristles that penetrate further between the teeth to remove plaque and debris. The Perio Toothbrush bristles are also ultra soft, reducing the likelihood of abrasion and recession while simultaneously allowing gentle gum stimulation. The polyester bristles of the Perio Toothbrush are less porous, creating a more hygienic brushing experience. The bristle also lasts approximately 50% longer than a standard nylon toothbrush. The Perio Toothbrush is great for all ages, including those undergoing orthodontic treatment, suffering from sensitivity or gum recession.
