Butler 1612 M Proxa Traveller Interdent is simple, easy-to-use. Interdental brush to remove dental plaque from areas between the teeth most commonly missed by toothbrushing alone. It is ideal for between natural teeth and around crowns, bridges, dental implants, and orthodontic appliances. It is manufactured with antibacterial coated nylon bristles in a cylindrical brush head configuration that can be easily adjusted up to 90 degrees for access to the hard-to-reach teeth toward the back of the mouth. A ventilated cap protects the brush between uses and when packed for travel.
