Philips Sonicare C1 ProResults HX6018/87 replacement brush heads (8 pack) – genuine Sonicare heads

The essentials for daily brushing

If you’re using a Philips Sonicare handle and want a reliable way to keep your routine consistent, these Philips Sonicare C1 ProResults replacement brush heads are built around one simple idea: better plaque removal than a manual toothbrush, using a shaped head and Sonicare’s movement pattern. On paper, they’re the sort of head you choose when you don’t want to overthink it—just keep the cleaning performance steady as your current head wears down.

They’re designed with contoured bristles and a W-profile intended to follow the shape of your teeth naturally. There’s also Sonicare’s proven technology claim behind them: up to 62,000 bristle movements, with dynamic fluid action that’s meant to help drive fluid deep between teeth and along the gumline. It’s not presented as a whitening gadget or a specialised treatment head—more like a dependable everyday brush head replacement.

What you’ll notice when cleaning

The main day-to-day difference with these heads is the way they do the contact and motion for you. Instead of trying to scrub every nook, the bristles and the design aim to fit around the teeth shape, while the “dynamic fluid action” focuses on cleaning between teeth and around the gumline. If your current brush head has dulled, you may also notice the cleaning feels less “alive” than it used to—replacing the head is often the easiest way to get that sensation back.

That said, it’s worth tempering expectations: this is a standard ProResults C1 head. It’s not the kind of upgrade you’d pick if you specifically want a very soft gum-focus, targeted orthodontic cleaning, or a special tongue or sensitivity programme—based on the information given, it’s aimed at general plaque removal.

When the replacement reminder helps (and when it won’t)

Philips includes BrushSync replacement reminder behaviour on the compatible ecosystem. The key idea is that you’ll know when it’s time to change the head thanks to two cues: it tracks how often and how hard you brush (on compatible handles), and blue bristles turn white. That’s a sensible approach because many people forget the “timing” part of replacement.

However, note the limitation in the wording: BrushSync works with compatible handles. If your Sonicare handle isn’t compatible, you may only rely on visual wear (the bristle colour change) or your own replacement schedule.
