Elgydium Clinic Interdental Brushes Refill ISO 3 x3 are specifically designed to be used with the Elgydium Clinic Trio Compact and Elgydium Clinic Flex handles. These refill brushes are ideal for individuals with medium interdental spaces, offering a thickness of 1.2 mm (ISO 3). Recommended for those with implants, braces, or exposed tooth necks, these brushes help reduce plaque buildup in hard-to-reach areas between the teeth, lowering the risk of cavities and gum disease. Each brush features a flexible head, ensuring a thorough clean, while the dual-colored bristles (black and white) provide practical benefits. The black bristles contrast against the teeth for easy insertion and help to visualize removed debris, while the white bristles detect any occasional bleeding, offering insight into gum health. These interdental brushes provide an easy and efficient way to maintain oral hygiene and keep interdental spaces clean.
