Philips Sonicare DiamondClean Smart 9750 Electric Toothbrush - Smarter

Our review of the Philips Sonicare DiamondClean Smart 9750 finds it best suited to people who want a more guided, higher-performing daily clean and care for sensitive gums. The single biggest reason to consider this toothbrush is its combination of proven sonic cleaning performance with connected coaching: the brush removes more plaque and stains than a manual brush while the app and built-in pressure sensor help correct habits over time. For those who prioritize gum health, stain removal and personalized feedback, this model delivers clear benefits.

Key Features

• Advanced plaque and stain removal: The high-performance sonic technology and included premium brush heads are designed to remove up to 20x more plaque and up to 100% more stains than a manual toothbrush for a visibly cleaner smile.
• Five brushing modes: Clean, White+, Gum Health, Deep Clean+ and Tongue Care let users choose the most appropriate routine for daily cleaning, whitening or gentle gum attention.
• Three intensity levels: Adjustable intensity lets users tailor power to sensitivity or preference for a comfortable, effective clean.
• Pressure sensor feedback: The light ring alerts when too much pressure is used, helping protect enamel and gums during regular brushing.
• Personalized guidance via app: When connected to the Philips Sonicare app the toothbrush provides coaching and feedback to improve technique and brushing coverage over time.
• Professional endorsement: As the leading dental professional recommended sonic toothbrush brand, it brings clinical focus to at-home oral care.

Who It's For

The DiamondClean Smart 9750 is a good choice for adults who want a feature-rich sonic toothbrush with guided feedback, multiple modes and high-quality brush heads for targeted cleaning and whitening. It suits people focused on improving gum health, reducing plaque and polishing stains without switching to professional treatments.

Those who should look elsewhere include buyers seeking a very basic, low-cost electric toothbrush or shoppers worried about long-term durability who prefer simpler, nonconnected models; some users have reported durability and vibration concerns after months of use, so cautious buyers may prefer a model with a simpler warranty path.
