Wisdom Pro Flex Interdental Brushes are designed with a flexible handle to reduce wire breakage and improve access to hard-to-reach areas. They feature coated wire suitable for use around metal fillings and to prevent sensitivity. Each brush comes with a hygienic cap for protection between uses. Available in a range of color-coded sizes to suit different interdental spaces. Use regularly to help maintain healthy teeth and gums, prevent gum disease and tooth decay, and promote fresh breath. To use, gently ease the brush into the space between the tooth and gumline or dental appliance, turning slightly. Clean the space by moving the brush gently back and forth. Rinse after use and replace the brush weekly or when bristles become worn. Safety warnings: Never force the brush into a space. Keep out of the reach of children. Excessive force and bending of the wire can lead to breakage, which may cause injury.
