DenTek Earth Friendly Sustainable Birch Wood Interdental Brushes Multi-size pack are made from 100% recyclable, sustainably grown Birch Wood known for its positive environmental credentials and premium quality. These ECO friendly interdental brushes feature tapered and narrow bristles in varying sizes to help you clean in the different sized gaps between your teeth and braces. This pack includes 2 x ISO 1/0.45mm, 2 x ISO2/0.5mm, 2 x ISO3/0.6mm interdental brushes that can help you to remove food and plaque between your teeth whilst supporting your gum health. The different sized brushes enable you to clean between both bigger gaps as well as small/tight gaps in your teeth.   Your dentist will be able to measure the spaces between your teeth and advise you of the interdental brush size you need. However, this product is perfect if you want to determine which size you need without visiting a dentist as the DenTek Earth Friendly Multi-Pack includes a variety of different sized brushes.  Interdental brushes remove more plaque than toothbrushing alone and dentists recommend daily interdental cleaning. Cleaning interdentally between your teeth will help you to reach the surfaces of your teeth a toothbrush cannot reach and remove plaque, a leading cause of tooth decay.  • Handle made from recyclable and sustainable Birch Wood • Tapered brush narrows at the tip to comfortably enter extra tight spaces • Expertly designed comfort wire that fits extra tight spaces comfortably  • Brush bends to create custom angles for easier access to clean between all teeth and braces • Includes a recyclable Sugar Cane cap to keep brushes clean between uses • Comes in recyclable cardboard packaging
