Have you ever imagined your daily brushing routine could feel less like a chore and more like a premium self-care ritual? In an age where personal health tech constantly evolves, the electric toothbrush has transformed from a simple cleaning tool into a sophisticated oral care companion. For years, I’ve delved deep into the world of electric toothbrushes, from foundational models to the most advanced innovations. The Philips Sonicare DiamondClean Smart 9700 stands out, promising not just a clean smile but a truly luxurious experience that redefines daily dental hygiene. This review will guide you through its groundbreaking features, unparalleled benefits, and whether this top-tier device is the ultimate upgrade your oral health deserves.
What is an Electric Toothbrush?
An electric toothbrush is an oral hygiene device that makes rapid, automatic brush head motions—either back-and-forth, oscillating-rotating, or vibrating at sonic speeds—to clean teeth more effectively than manual brushing. Its core principle lies in consistent, controlled movements that reach more surfaces and remove plaque more thoroughly.
The evolution of the electric toothbrush began with simple battery-operated models, progressing through oscillating-rotating designs that physically scrubbed teeth. Today, sonic technology dominates the premium market. These brushes utilize high-frequency vibrations, often exceeding 30,000 brush strokes per minute, to create dynamic fluid action that reaches between teeth and along the gumline. Common types include oscillating/rotating, sonic, and ultrasonic, with sonic models like the DiamondClean Smart 9700 offering a blend of power and gentle care.
The Unparalleled Benefits of Electric Toothbrushes (and the 9700)
Stepping up from a manual toothbrush to an electric model, especially a sophisticated one like the Sonicare DiamondClean Smart 9700, brings a host of benefits that significantly enhance oral health. The primary advantage is superior cleaning efficiency. Electric toothbrushes remove significantly more plaque than manual ones, thanks to their high-speed motions and consistent pressure.
Beyond basic cleaning, these devices are instrumental in improving gum health by gently massaging the gumline, reducing inflammation, and preventing gingivitis. They excel at breaking down and removing stubborn plaque and harmful bacteria, leading to a noticeably fresher mouth. For those concerned about aesthetics, the advanced cleaning action of electric toothbrushes effectively polishes away surface stains, contributing to whiter teeth and preventing future discoloration. Moreover, their intuitive design, often featuring built-in timers and pressure sensors, makes them incredibly convenient and easy to use, particularly beneficial for individuals with dexterity issues or those simply looking for guided brushing.

At the heart of the DiamondClean Smart 9700’s luxury experience is its intelligent technology, seamlessly integrated with a user-friendly app. This connection transforms brushing from a routine into a guided, personalized session. The brush provides real-time feedback, showing you exactly where you’re brushing and if you’re missing any spots through mouth-mapping technology. This personalized coaching is akin to having a dental professional guiding your hand, ensuring every tooth receives optimal attention. Crucially, an adaptive pressure sensor alerts you if you’re brushing too hard, protecting your gums and enamel from damage. Furthermore, the toothbrush intelligently recognizes the smart brush head attached, automatically optimizing the brushing mode and intensity for superior results tailored to that specific head’s function.
Multiple Brushing Modes & Intensities
Adaptability is key to personalized oral care, and the DiamondClean Smart 9700 delivers with a variety of brushing modes and adjustable intensity settings. It typically includes modes such as:
- Clean: For daily, thorough plaque removal.
- White+: Designed to remove surface stains and whiten teeth.
- Deep Clean: Provides an invigorating, extended cleaning session for hard-to-reach areas.
- Gum Health: Specifically engineered for gentle yet effective cleaning along the gumline.
- Tongue Care: For a fresh breath experience, utilizing a dedicated tongue brush.
Users can also choose from multiple intensity levels, allowing them to customize their brushing experience to their comfort and specific oral needs, whether sensitive gums or a desire for a more vigorous clean.
Premium Design & Accessories
From the moment you unbox it, the DiamondClean Smart 9700 exudes sophistication. Its sleek, ergonomic design not only looks elegant on any bathroom counter but also offers a comfortable grip, making it easy to maneuver. Unlike some brushes with grooves that can harbor grime, its seamless construction is easy to clean and maintain. The luxury extends to its charging solutions: a stylish charging glass allows for inductive charging simply by placing the brush in it, doubling as a convenient rinsing cup. For travel, a premium USB-A charging travel case ensures your brush stays charged and protected on the go, making it an ideal companion for discerning travelers. The 9700 package is typically generous, including several smart brush heads—such as Plaque Control, Gum Care, Whitening, and a Tongue Care brush—each designed for specific oral care goals and recognized by the brush for optimal performance.

While the upfront cost is significant, the peace of mind that comes with superior oral care and a truly luxurious daily routine can make it a worthwhile splurge for those committed to their dental well-being.
Mastering Your Oral Care: Using the DiamondClean Smart 9700
Getting the most out of your DiamondClean Smart 9700 is simple, but a few tips can enhance your experience and maximize its benefits. First, ensure your brush head is properly seated on the handle and that the device is fully charged, either in its elegant charging glass or via the travel case.
When brushing, apply a pea-sized amount of toothpaste. Instead of scrubbing, let the sonic technology do the work. Gently guide the brush head across your teeth, holding it at a slight angle towards the gumline. Allow the bristles to thoroughly clean each tooth surface. The built-in two-minute timer ensures you brush for the dentist-recommended duration, while the QuadPacer guides you to clean each quadrant of your mouth equally. Pay close attention to the pressure sensor; it will alert you if you’re pressing too hard, helping you protect your gums and enamel. After each use, rinse the brush head thoroughly and wipe down the handle. Remember to replace your smart brush heads every three months, or sooner if the indicator bristles fade, to maintain optimal cleaning performance.
Where to Find Your Sonicare DiamondClean Smart 9700
For those ready to elevate their oral care, the Philips Sonicare DiamondClean Smart 9700 is widely available from reputable retailers. You can typically find it at major electronics stores, large department stores, and specialized oral care shops. Online marketplaces and the official Philips Sonicare website are also excellent sources, often providing competitive pricing and direct shipping. When purchasing, always ensure you buy from an authorized dealer to guarantee product authenticity and access to warranty support.
Conclusion
The Philips Sonicare DiamondClean Smart 9700 truly stands as a testament to what an Electric Toothbrush can be, transforming a routine task into an exceptional experience. It blends cutting-edge sonic technology with intelligent features like real-time feedback and smart brush head recognition, delivering an unparalleled level of clean and personalized care.
