Philips Sonicare C3 Two-in-One Brush Heads (2-Pack) — Six Months of Deep Clean! $28.96 CAD (33% Off)

Amazon.ca has the Philips Sonicare C3 Two-in-One replacement brush heads (2-pack) for $28.96 CAD — list price is $42.99, so 33% off. Prime members ship free; otherwise free over $35.

Two heads at three months each is half a year of brushing, which is the interval dentists actually recommend and almost nobody follows. The C3 is a two-in-one: a dense pentagonal cluster in the centre handles polishing and stain removal — Philips claims up to 100% more stain removal in three days versus a manual brush — while the soft-touch back lets the bristles follow the tooth surface instead of skipping over it. Overall the claim is up to 1000% more plaque removal than a manual toothbrush, backed by 62,000 bristle movements and Fluid Action pushing the toothpaste slurry between teeth and along the gumline.

If your handle supports BrushSync it tracks how long and how hard you brush and lights up when the head is due; the blue bristles fading to white is the backup signal.

They click onto every Sonicare click-on handle except Philips One and e-Series. 70% of the plastic in the head is bio-based and the packaging is paper-based. 4.7 stars from 1,742 ratings, two-year manufacturer warranty.

At full price these are pricey for two pieces of plastic and nylon, so stocking up when they drop is the sensible move — they don't go bad sitting in a drawer.
