NK CARE Sonic Toothbrush Replacement Heads — 8 Pack

This eight-pack of NK CARE Sonic Toothbrush Replacement Heads provides a full year of fresh bristles when replaced every three months as recommended by dental professionals. Each head features end-rounded DuPont Tynex nylon bristles arranged in a diamond-shaped pattern that concentrates cleaning action at the gumline where plaque accumulates most aggressively. A color-fade indicator strip on the back of each head gradually changes from blue to white over approximately 90 days of twice-daily use, signaling when replacement is due without guesswork. The heads click onto the NK CARE Sonic Electric Toothbrush handle with a press-fit connector and include a hygienic snap-on cover for travel use. Each brush head measures 22mm wide by 30mm long — compact enough to access rear molars comfortably. The bristles are medium-firm hardness, suitable for the majority of adults. This pack is available in standard and sensitive variants — the sensitive heads use softer, thinner filaments rated at 0.10mm diameter for users with gum recession, recent dental work, or heightened tooth sensitivity. Individually sealed in recyclable paper-backed blister packs.
