Replacement Heads - medium bristles (2pk)

Replacement Heads weigh only 7% of the total toothbrush and save you from throwing away the other 93% of a toothbrush or wasting fuel attempting to return to seller. Heads are made of surgical grade nylon and have 75% more tufts than ordinary toothbrushes. Contains 3,000 fine and polished DuPont Tynex® nylon bristles. The bristles radiate out from the head to give soft massage to sensitive gum tissue and excellent plaque removal. Heads last about 3 months of average use and are discarded after use, like a razor blade.
