Life Brand Interdental Brushes for Ultra Tight Spacing are engineered to maintain oral hygiene by targeting areas inaccessible to regular toothbrushes. The flexible handle and a brush head that bends up to 90 degrees allow for exceptional reach, especially around bridges and braces. These brushes effectively remove plaque and food particles from ultra-tight spaces. For optimal use, gently guide the brush in and out between teeth, rinse after each use, and replace it every 10 days or when signs of wear appear.
