Can I use my interdental brushes more than once?
Just like any toothbrush, interdental brushes can be washed out after use, and used again. The life of an interdental brush depends on how often it is used and how well it is cleaned. Careful use and regular rinsing can extend the life of a brush considerably: as a rough guide, each brush will last 2-3 days or as long as a week. Some choose to use their brushes only once.
