Oral-B is synonymous with professional dental hygiene and years of experience in the service of your dental health. Oral-B Essential Dental Floss unwaxed thoroughly cleans places you cannot reach with your toothbrush. The unwaxed surface makes for a firm grip between your fingers. The floss can be guided precisely into your inter-dental spaces to remove plaque and food particles. Used regularly, this will help prevent caries and may even save you from unpleasant toothaches and expensive dental work.
