Editor's Pick: After about three months of use, toothbrush head bristles start to splay, and cleaning power noticeably drops. This A3 head features triangular bristles that reach the surfaces between teeth more easily, and with sonic vibration technology, it makes cleaning pretty effortless. The extended side bristles naturally cover the gumline while brushing, which is great for gum health. The handle has a BrushSync smart reminder—when it's time to replace the head, the blue bristle fades to white, so you don't have to keep track of the days yourself. It's compatible with all Philips click-on series toothbrushes, and a 2-pack will easily last you six months.
