Dental floss and toothbrush used by Preventive Dentists. “These are Dentists who have studied the science and art of preventing disease from ever taking hold in the mouth. These Dentists do not want to fill another cavity, or pull another diseased tooth…The science behind our toothbrushes and dental floss was developed by a Medical Doctor, not a Dentist. The products depend on this science…Our toothbrush bristles are very thin with carefully polished tips. This makes the bristles very soft and gentle, compared to other toothbrushes. Since this part of the toothbrush is actually what is useful, we focus our attention there…Our floss is very different, too. Its many thin strands of nylon enable our floss to disrupt and disorganize the bacterial plaque, which is the key to preventing tooth decay and gum disease.” One of my longtime readers recommended this method. She has been using it with success for years. Products are made from nylon.
