Cleaning with an interdental brush prevents gum inflammation, cavities and bad breath. This pack of Extra Soft InterDental Brush contains 6 different sizes and 1 cap, and sold at 8pcs/pack. This unique range of Interdental Brushes has extra soft filaments for gentle cleaning. The six colour-coded sizes also have plastic-coated wire for safer use.
