Ensure your Oral-B electric toothbrush performs at its best with the Oral-B Pro Precision Clean Toothbrush Heads. This 8-pack features advanced bristle technology designed to remove up to 100% more plaque in hard-to-reach areas than a manual toothbrush. The unique CleanMaximiser indicator features bristles that fade from green to yellow, signaling when it's time for a replacement to guarantee optimal cleaning power and gum health every time. Each brush head combines three specialized bristle types for a comprehensive, tooth-by-tooth clean that is soft on gums yet highly effective on plaque. Crafted from high-quality synthetic bristles, plastic, and metal, these replacement heads are compatible with all Oral-B electric rechargeable toothbrush handles (except Pulsonic & iO models). For ongoing oral health, replace your brush head every three months or as soon as the color-changing bristles indicate. Please note: this product comes with a standard UK 2-pin plug. For use with a 3-pin UK socket, a suitable adapter is required. This does not affect the product's performance or safety. Not for use by children under 3 years of age.
