## Long description

The Philips Sonicare DiamondClean 9000 Series HX9911/88 is an advanced sonic toothbrush for adults that combines powerful cleaning with personalised care. It uses Sonicare technology to deliver up to 31,000 vibrations per minute for effective plaque removal and whiter teeth. The set includes one handle and one C3 Premium Plaque Control brush head and offers a slim travel case and long-lasting battery suitable for everyday use and travel.
Advantages
This toothbrush removes surface stains up to 100% more effectively than a manual toothbrush and can produce visibly whiter teeth in about three days when used as directed. The C3 Premium Plaque Control brush head increases surface contact with soft, flexible sides and curved bristles to reach hard-to-clean areas. DiamondClean 9000 combines powerful plaque removal—up to 10x more than a manual toothbrush—with a pressure sensor that alerts you when you brush too hard and BrushSync technology that automatically selects the appropriate mode when the compatible brush head is attached.
Suitable for
Adults seeking daily plaque removal and stain reduction
Users who want personalised brushing with multiple modes and intensities
People with sensitive gums who need pressure feedback and gentler settings
Frequent travellers needing a compact travel case and long battery life

How to use
Attach the C3 Premium Plaque Control brush head to the handle, select one of the four modes and an intensity level that suits your comfort. Place the brush head at a 45° angle to the gum line and move it slowly from tooth to tooth, allowing the sonic vibrations to do the work rather than scrubbing. If the pressure sensor alerts you, reduce pressure and let the brush clean the surface. Use the White+ mode as directed for stain reduction and follow the brush head replacement guidance shown in the app or on the product packaging.
Usage recommendations
For best results, brush twice daily for two minutes, connect the handle to the Sonicare app for personalised coaching and progress reports, and replace the brush head every three months or sooner if bristles show wear.
