Root canal stoppers are the small silicone discs that turn every file into a working-length reference. Ours are medical-grade silicone with a consistent bore — tight enough to stay where you set them through multiple irrigation passes, soft enough not to flag or fray on the file flutes.

Available in multiple colors for quick size identification. Autoclavable and built to survive the chemistry of NaOCl, EDTA and CHX.
