Philips Sonicare DiamondClean Prestige 9900 series DiamondClean Prestige HX9992/12 Sonic electric toothbrush with SenseIQ - Blue

The Philips DiamondClean Prestige HX9992/12 is a sonic electric toothbrush for adults that combines high-frequency sonic cleaning with SenseIQ sensing technology. The brush adapts to your brushing pressure and technique to provide thorough plaque removal and tailored care. The kit includes one handle and one brush head and runs on a built-in lithium‑ion battery. Multiple modes — Daily Care, Deep Clean, Gum Care, Sensitive and Whitening — allow you to select the appropriate intensity and focus for oral hygiene needs.

Advantages

SenseIQ technology senses brushing behaviour and adapts power and motion to protect gums and improve plaque removal, including in hard-to-reach areas. The sonic motor delivers rapid brush strokes for effective cleaning while the integrated timer supports recommended brushing duration. A rechargeable lithium‑ion battery offers long runtime and consistent performance. The available modes provide flexibility to address sensitivity, gum health, whitening and deeper cleaning.

Recommendations

Use the Gum Care or Sensitive mode if you experience gum sensitivity. Replace the brush head every three months or sooner if bristles are worn. Consult a dental professional for personalised advice.
