Please read the leaflet inside the pack before use. Use as directed by your dental or oral health professional. Simply slide the head in between your teeth and gently move back and forth to remove plaque and food particles, rinsing the brush head clean between each use. Choose a brush size that inserts easily without force and insert it between the gaps of your teeth with a gentle twisting action. Use straight in-and-out movements when cleaning between your front teeth. For back teeth, use your finger to bend the brush head gently to around 60 to 90 degrees for easier access. Designed to be reusable. The Australian Dental Association recommends flossing or cleaning your interdental spaces at least once per day. The Piksters Interdental Brushes can be used as an alternative or an addition to dental flossing.
