Product description GUM® BI-DIRECTION Interdental Brushes Interdental brushes help clean those hard-to-reach spaces between your teeth, especially at the back of your mouth, where plaque and tiny bits of food can easily accumulate. These professionally recommended interdental brushes are especially useful for cleaning both wide and tight spaces between your teeth. You can also use them if you have a bridge, implants, or braces. The GUM BI-DIRECTION toothbrush has a clever rotating design that allows it to be clicked into two different positions to clean different areas of the mouth. We recommend using it at least once a day, preferably after your evening meal. Key product featuresThe head can be rotated 90 °: the straight position is ideal for the front teeth, while in the L position it can easily reach the back teethSuper strong wire provides increased durability so you can use the brush for longer Longer handle provides easy access to all areas of the mouth Recommended by dentists
