Traditional string floss or dental tape may be some dentists' preferred choice, but water flossers are considered an adjunct to brushing and traditional manual flossing. "It feels quite gentle, but it is quite a strong force through the little triangle between the teeth," says Dr. Creaven. "It's pushing the food and debris so it will pop off the teeth and away from that area." Conventional and water flossing are suitable for cleaning thoroughly, but traditional flossing should be a part of your dental hygiene routine.
