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 designed to penetrate further between teeth, removing plaque and debris. The ultra-soft bristles reduce the likelihood of abrasion and recession while simultaneously allowing gentle gum stimulation. The polyester fibers are less porous, for a more hygienic brush and last approximately 50% longer than the standard nylon-bristle brush. Great for all ages, including those undergoing orthodontic treatment, suffering from sensitivity or gum recession.
