The Dr. Collins Perio Toothbrush is unlike any other toothbrush on the market. Its patented, super-thin tapered bristles penetrate further between the teeth and below the gums to remove plaque biofilms and food debris better than common non-tapered bristles. The bristles are also ultra soft, reducing tooth abrasion and recession while simultaneously massaging the gums. Polyester bristles are also less porous than the usual nylon bristles found on most toothbrushes helping to minimize bacterial growth. The bristles also last approximately 50% longer than standard nylon bristles. The Perio Toothbrush is great for all ages, including those undergoing orthodontic treatment, suffering from sensitivity or gum recession. NOTE: Available Colors are Blue, Pink & Purple. Color selection will be made at random. Color choice cannot be specified.
