An interdental brush is a small dental tool designed to clean between teeth, where regular toothbrushes may not reach effectively. It consists of a thin handle and a small, bristled head that comes in various sizes to fit different gaps between teeth. Using an interdental brush helps remove plaque and food particles, promoting better oral hygiene. These brushes are often recommended by dentists as part of a daily dental care routine. They can be especially beneficial for individuals with braces, dental implants, or larger gaps between teeth. Regular use can help prevent gum disease and cavities, contributing to overall dental health.
