Pricing Insight
Positioned at the upper echelon of electric toothbrushes, the Philips Sonicare DiamondClean Smart 9700 carries a premium price tag reflective of its advanced technology and comprehensive feature set. While it represents a significant upfront investment, it is crucial to consider this within the context of long-term dental health. Potential buyers should monitor major retailers for sales events, particularly around holidays, which might offer opportunities for savings. It’s also wise to factor in the recurring cost of genuine Philips Sonicare replacement brush heads, which, while more expensive than generic alternatives, are engineered to work optimally with the smart features of the 9700.

Comparison with 1 Alternative: Oral-B iO Series 9
When considering high-end smart toothbrushes, the most direct competitor to the Sonicare DiamondClean Smart 9700 is often the Oral-B iO Series 9. While both aim to deliver superior cleaning and smart guidance, they achieve this through distinct technologies: Related: Best Smart Electric Toothbrushes with AI Coaching for Advanced Oral Care in USA (2026)
- Cleaning Action: The DiamondClean Smart 9700 utilizes powerful sonic vibrations that create a dynamic fluid action, sweeping away plaque. The iO Series 9, on the other hand, employs a unique oscillating-rotating motion combined with micro-vibrations, focusing on individual tooth cleaning. The choice often comes down to personal preference for the feel of the cleaning action – some prefer Sonicare’s gentler sweep, while others favor Oral-B’s more intense, scrubbing sensation.
- Smart Feedback: Both brushes offer sophisticated app-based coaching. Sonicare’s app provides a visual 3D map of your mouth, highlighting missed spots and guiding coverage. Oral-B’s iO app similarly uses AI and 3D tracking to identify and guide brushing in all areas. Both systems are highly effective at promoting better brushing habits.
- Design and Accessories: Both units boast premium designs and offer useful accessories like charging bases and travel cases, although the aesthetics and specific features (e.g., Sonicare’s charging glass vs. iO’s magnetic charger) differ.
Ultimately, neither is definitively “better”; they offer different approaches to achieving excellent oral hygiene. The decision between the two often hinges on whether you prefer the feel of sonic cleaning or the oscillating-rotating action, and which app interface resonates more with your personal preferences.
Final Verdict
The Philips Sonicare DiamondClean Smart 9700 undeniably stands as a pinnacle in personal oral care technology. Its combination of powerful sonic cleaning, intelligent sensors, and personalized app guidance offers an unparalleled brushing experience that is genuinely designed to improve oral health outcomes. For those who view dental care as a non-negotiable investment in their overall well-being and appreciate the integration of cutting-edge technology into their daily routine, the DiamondClean Smart 9700 is very likely worth the investment.
While the cost is significant, the potential for reduced dental issues, a brighter smile, and the confidence that comes with superior oral hygiene can certainly justify the expense for the right user. If you are serious about transforming your brushing habits and achieving the cleanest, healthiest mouth possible, and are prepared to engage with its smart features, the Philips Sonicare DiamondClean Smart 9700 could be the ultimate upgrade your oral care routine deserves.
