Abstract
A gum stimulator is disclosed which has a removable brush composed of a high-density of soft thin fibers. The brush tip is disposed on a handle, which may comprise an end of a toothbrush, and is mounted on a shaft which extends from the handle. In one embodiment, the brush extends at an angle of about 90 degrees from the handle and includes long fibers surrounded by short fibers which penetrate the interstitial spaces between the teeth to provide complete gum stimulation without casuing tissue damage.
