4PK Sonicare C3 Premium Plaque Defence Brush Heads Replacement - Black

Philips Sonicare DiamondClean Smart replacement br

K.G. Electronic is the only Australian based online store where I have found the genuine Philips Sonicare DiamondClean Smart replacement brush heads. I have purchased through K.G. Electronic multiple times and cannot recommend them enough. K.G. Electronic also have frequent promotions/sales both on their site and eBay store. I recommend checking-in frequently to snag a good deal.

You’ll always get the best possible clean with our BrushSync™ mode-pairing feature*. The  Philips Sonicare C3 Premium Plaque Control brush head syncs with your BrushSync™ enabled Philips Sonicare toothbrush handle****, selecting the optimal brushing mode and intensity level for exceptional cleaning. All you need to do is start brushing.

And thanks to its flexible design, it removes up to 10x more plaque from hard-to-reach areas* for a truly deep clean along the gum line and between teeth.

You get a personalized clean every time you brush with our adaptive cleaning technology. Soft rubber sides flex to let Premium plaque control adapt to the shape of your teeth and gums, absorbing any excess brushing pressure and enhancing our sonic cleaning power. Bristles can then adjust to the shape of your teeth and gums so you get up to 4x more surface contact than a regular brush head** for deeper cleaning in hard-to-reach areas.

Your Sonicare brush head and handle are the ultimate team. Enhancing our sonic technology, they give you unrivalled cleaning. High-speed vibrations in your toothbrush handle power up to 62,000 brush movements per minute that whip up your toothpaste into plaque fighting bubbles, driving them deep between your teeth and along the gum line for exceptional cleaning.

Brush heads become less effective after 3months of use, but with BrushSync™ you'll be reminded before this happens. Your smart toothbrush will track how often and how hard you brush, and will notify you when it’s time for a replacement. Don’t have a smart Philips Sonicare toothbrush? Just monitor your blue replacement bristles, and when they turn white you’ll know it’s time for a fresh brush head.

All Philips Sonicare brush heads are safe and gentle on teeth and gums. During tests, each brush head is put through its paces to ensure durability and an exceptional performance every time you brush. 

Your C3 Premium Plaque Control brush head fits perfectly with any Philips Sonicare toothbrush handle, except PowerUp Battery and Essence. Simply click on and off for easy replacement and cleaning.


This comes with a 12-year warranty.
