Product description

Philips Sonicare DiamondClean Black HX9351/04 Rechargeable Toothbrush

Philips Diamond clean toothbrush HX9352 is finished in sleek matte black ceramic, with hidden led controls. The lights glow from within, and fade when not in use, so all you see is the sheer simplicity of the stylish black handle. Not only is it the most stylish toothbrush, it offers unbeatable performance. This is the ultimate sonic toothbrush from Sonicare, designed to improve oral health whilst whitening teeth. DiamondClean is clinically proven to remove up to 100% more plaque biofilm in hard-to-reach areas and to whiten teeth up to two times better within one week than a manual toothbrush.

The handle, high-density, diamond-shaped bristles and range of five cleaning modes offer a clinical-level clean that dentists recommend to their patients.

Why choose Sonicare?

Taking good care of your teeth and mouth is essential, because your oral health can directly affect your overall health. While it doesn't mean you should say goodbye to the dentist's chair forever, an effective daily routine, using a good toothbrush, such as a Sonicare, will help. Our brushes provide up to 100% better plaque removal in hard-to-reach areas versus a manual, thanks to the patented sonic technology.

The Philips Sonicare brand is a leader in oral health care, and is backed by more than 140 publications and abstracts representing clinical and laboratory studies conducted at more than 40 universities and research institutes worldwide. Philips Sonicare power toothbrushes are proven to promote and improve oral health, from reducing plaque build-up to improving overall gum health. They have also demonstrated the ability to increase patient compliance to oral health and hygiene regimens between dental visits. Over 22 million enthusiastic users worldwide testify to the great experience of using Philips Sonicare toothbrushes.


Naturally Whiter Teeth

Daily use of the White mode can help you achieve teeth that are noticeably whiter in just 1 week. Proven to remove coffee, tea, tobacco and red wine stains. The advanced new handle, high-density, diamond-shaped bristles and range of five cleaning modes offer a clinical-level clean that dentists, with absolute confidence, recommend it to their patients.

Gum Health

Most adults suffer from gum disease at some point in their lives. Thankfully, DiamondClean is clinically proven to improve gum health in just two weeks. Its unique Gum Care mode targets the gum line, removing plaque while stimulating gums.

Clinically proven safe and gentle

Your Sonicare is safe to use on: braces (brush heads wear out sooner when used on braces), dental restorations (fillings, crowns, veneers) and periodontal pockets.

Philips' most stylish electric toothbrush to date

Cased in sleek matte black ceramic, Sonicare DiamondClean is not only Philips' most advanced brush yet, it's also our most stylish. The technology in the handle is hidden so the brushing modes are only illuminated when in action, when off, display becomes invisible for a clean look.

Highly charged - Dual charging system

Philips Sonicare DiamondClean possesses a highly impressive three week charge but when users need to recharge their brush, DiamondClean comes equipped with:

1. Unique charging glass

A unique charging glass that can be used for mouth rinsing, as well as the latest in conduction technology to charge the toothbrush as it rests in the glass - making it stylish enough to display in the most fashion-forward bathroom.

2. Revolutionary USB travel case

When traveling or on the go, Sonicare DiamondClean is designed for convenience with users being able to keep their brush fully charged using a revolutionary USB travel case that can be plugged into almost any lap top computer and saves the hassle of having to pack plugs and adaptors.

Unique brush heads

Diamond-shaped bristles provide a greater surface area for an exceptional cleaning and whiter teeth teeth in just one week. The uniquely designed diamond bristle heads have 44% more bristles than Philips Sonicare's standard sized ProResults, providing you with both superior plaque removal and whiter teeth.

2 sizes brush heads available

1- Standard brush head: For focused cleaning in areas of special need.

2- Mini brush head: For orthodontic patients and those with smaller mouths.

Reminder bristles

Reminder bristles gradually fade, indicating when it's time to replace brush heads. If a patient uses their brush head twice a day for the full two minutes, it needs to be replaced every three months.

Easy-start programme

Gently increases power over the first 14 uses to ease into the Sonicare experience.

2-minute timer

2-minute timer automatically tracks brushing time, ensuring recommended brushing regime is followed and turns the toothbrush off when brushing is complete.

Quadpacer interval timer

30 seconds interval timer indicates when you have completed each quadrant of your mouth and signals for you to move on, resulting in more consistent cleaning throughout your mouth

Long battery life

Exceptionally long 3 weeks of use on a single full charge or 42 2-minute brushings

5 brushing modes

Philips Sonicare DiamondClean is Sonicare's most versatile brush yet and is suitable for a wide range of consumers due to its five bespoke brush modes.
