Sonicare vs DiamondClean Smart 9300 Review

Let’s start by examining the standout aspects of the DiamondClean Smart 9300, the more technologically advanced of the two models.

9300 Key Features and Specs

  • Smart Sensor Technology: This is the marquee feature that truly sets the 9300 apart. Using actual sensors in the brush head, it can automatically detect your brushing style and adjust the intensity accordingly. In my experience, this smart coaching proved invaluable in correcting bad habits and ensuring a more consistent, effective clean.
  • App Connectivity: Pair the 9300 with the Sonicare app (available for iOS and Android), and you’ll gain access to real-time feedback, personalized coaching, and detailed tracking of your brushing sessions. As someone who loves data-driven insights, I found this integration incredibly useful in optimizing my routine.
  • Four Smart Brush Heads: The 9300 comes equipped with four different brush heads designed for specific needs: Premium Plaque Control, Premium Gum Care, Premium White, and TongueCare+. These automatically sync with the appropriate brushing mode when attached, streamlining the customization process.

9300 Benefits

  • Personalized Coaching: Thanks to the smart sensors and app connectivity, the 9300 can adapt to your unique brushing style, providing real-time guidance to improve your technique and address problem areas effectively.
  • Convenient Tracking: The app’s detailed tracking capabilities let you monitor your progress over time, fostering accountability and helping you establish consistent oral hygiene habits.
  • Tailored Cleaning: With the specialized brush heads and corresponding modes, you can easily target areas of concern, whether it’s plaque buildup, gum sensitivity, or surface stains.


  • Premium Price Point: The advanced technology in the 9300 comes at a higher cost, which may not be feasible for budget-conscious consumers.
  • App Dependency: While the app integration is a significant advantage, it also means that your brushing experience is somewhat reliant on your smartphone or tablet being nearby and charged.

DiamondClean Classic 9000 Review

Now, let’s shift our focus to the DiamondClean Classic 9000, a more traditional (yet still highly capable) electric toothbrush from Philips.

Sonicare DiamondClean 9000 Specs and Overview

  • Five Brushing Modes: Clean, White, Deep Clean, Gum Health, and Tongue Care – a comprehensive range to address various oral hygiene needs.
  • Quadpacer and Smartimer: These handy features help ensure even brushing across all areas of your mouth and encourage adherence to the recommended two-minute brushing duration.
  • Premium Travel Case: The 9000 comes with a stylish and compact travel case, perfect for keeping your brush protected and charged on the go.
  • Two Brush Heads Included: A standard Clean brush head and a compact-sized brush head for precision cleaning in hard-to-reach areas.

While the 9000 may lack the advanced smart features of the 9300, it still packs a punch in terms of cleaning power and thoughtful design elements. During my testing, I found the five distinct brushing modes to be effective and well-suited for different situations, such as a more vigorous Deep Clean after a meal or a gentle Gum Health mode when my gums felt sensitive.

DiamondClean Classic vs DiamondClean Smart: Features Comparison

When comparing the Philips Sonicare DiamondClean Classic to the DiamondClean Smart series – which includes the 9500, 9700, and the prestigious 9900 Prestige – the upgrades are noteworthy. The DiamondClean Smart range, acclaimed as the best electric toothbrush, integrates advanced technology offering different smart brush head types that automatically select the appropriate brushing mode and smart features. These smart sensors provide real-time feedback for an unparalleled cleaning experience.

The 9300 model starts the lineup with 3 brush heads, while the 9500 and 9700 include 4 brush heads, enhancing the versatility for different dental needs. Each toothbrush handle is designed for ease of use with click-on brush heads, making the transition between them seamless. The best Sonicare experience is elevated with these features, ensuring that users receive a thorough clean tailored to their specific oral health requirements.

Moreover, the Philips Sonicare DiamondClean Smart series showcases its prowess with the inclusion of rechargeable electric capabilities and a sophisticated interface that guides users through each cleaning session. The innovative technology does not just stop with customizable cleaning modes; the smart brush head types automatically engage with the toothbrush handle, dictating the brushing mode and smart sensors to optimize every brushing session for the best possible oral health outcome.

Between the Philips One by Sonicare and the high-end 9900 Prestige, the broad range of Philips Sonicare toothbrush offerings cater to a variety of preferences and needs. However, the DiamondClean Smart series, especially models like the 9500 and 9700, stand out for their comprehensive care capabilities, making any of them a contender for the best Sonicare electric toothbrush. The emphasis on smart sensors and sonicare brush heads tailored to individual dental health needs truly sets the DiamondClean Smart apart in the landscape of oral hygiene solutions.

To give you a clearer picture of how these two models stack up, let’s break down their key features side by side:

As you can see, the 9300 takes the lead in terms of advanced smart features and customization options, while the 9000 offers a more streamlined experience with a focus on robust cleaning modes and longer battery life.

Brushing Modes and Settings

Both models offer a variety of brushing modes to cater to different oral care needs. However, the implementation differs slightly:

DiamondClean 9000:

  • Clean Mode: The standard mode for a thorough, all-around clean.
  • White Mode: Designed to gently polish away surface stains for a brighter smile.
  • Deep Clean Mode: A more intense pulsating action to dislodge stubborn plaque and debris.
  • Gum Health Mode: A gentler setting ideal for massaging and improving gum health.
  • Tongue Care Mode: Specifically designed to freshen breath by removing bacteria from the tongue.

You can cycle through these modes using the dedicated button on the brush handle, allowing for easy adjustment during your brushing session.

DiamondClean Smart 9300:

  • Clean Mode: Similar to the 9000, this is the default mode for daily cleaning.
  • White+ Mode: An enhanced version of the whitening mode, designed to remove stains and polish tooth surfaces more effectively.
  • Deep Clean+ Mode: An even more powerful pulsating action compared to the 9000’s Deep Clean mode, providing a deeper clean for those who need it.
  • Gum Health Mode: Identical to the 9000’s gentle gum massaging mode.

The key difference here is that the 9300’s modes automatically adjust their intensity and pulsation patterns based on your brushing style, thanks to the smart sensor technology. Additionally, the 9300 lacks a dedicated Tongue Care mode, though you can still use the brush on your tongue with any of the other modes.

Battery Life and Charging

Both the 9000 and 9300 feature lithium-ion rechargeable batteries, but there’s a notable difference in their battery life:

  • DiamondClean 9000: Offers an impressive battery life of up to 3 weeks on a single charge.
  • DiamondClean Smart 9300: Has a slightly shorter battery life of up to 2 weeks per charge.

This discrepancy can be attributed to the additional power requirements of the 9300’s smart sensor technology and Bluetooth connectivity. However, both models come with convenient travel cases that allow you to charge the brush on the go, ensuring you never run out of power during your travels.

Benefits of Smart Sensor Technology

While the DiamondClean 9000 is an excellent brush in its own right, the smart sensor technology in the 9300 is a game-changer when it comes to personalized guidance and improving your brushing technique.

During my testing, I found the real-time feedback from the 9300 to be incredibly insightful. It would alert me when I was brushing too hard, applying too much pressure, or missing certain areas of my mouth. This kind of coaching is invaluable, as it helps correct bad habits and ensures a more consistent, effective clean with every session.

The smart sensors also automatically adjust the brushing intensity and pulsation patterns based on your unique style, further tailoring the experience to your needs. For instance, if you tend to brush aggressively, the 9300 will dial down the intensity to prevent potential damage to your gums. Conversely, if you’re a gentler brusher, it will increase the pulsations to ensure a thorough clean.

Replacement Brush Head Options

Both the 9000 and 9300 offer a range of replacement brush head options to suit different oral care needs:

DiamondClean 9000:

  • Standard Clean Brush Head: The go-to option for daily cleaning and plaque removal.
  • Compact Clean Brush Head: A smaller head for precision cleaning in tight spaces.
  • Gum Care Brush Head: Featuring softer bristles for gentle gum massaging and improved gum health.

DiamondClean Smart 9300:

  • Premium Plaque Control Brush Head: Designed specifically for removing up to 7x more plaque than a manual toothbrush.
  • Premium Gum Care Brush Head: Featuring ultra-soft bristles and specialized tufting patterns to gently massage and improve gum health.
  • Premium White Brush Head: Utilizes densely-packed bristles and polishing cups to effectively remove surface stains and whiten teeth.
  • TongueCare+ Brush Head: A unique brush head designed to remove bacteria and freshen breath by cleaning the tongue.

While both models offer a solid range of options, the 9300’s brush heads are more specialized and technologically advanced, leveraging features like densely-packed bristles and polishing cups for enhanced cleaning performance.

Philips Sonicare 9300 vs 9000 – Which is Better?

After extensively testing and comparing these two flagship models, it’s clear that they cater to different user needs and preferences. Here’s my take on which one might be better suited for you:

Choose the DiamondClean Smart 9300 if:

  • You value personalized coaching and real-time feedback to improve your brushing technique.
  • You appreciate the convenience of app connectivity and detailed tracking of your oral hygiene routine.
  • You’re willing to invest in the more premium price point for advanced smart features and specialized brush heads.
  • You prioritize tailored cleaning experiences for specific needs like plaque control, gum care, or whitening.

Choose the DiamondClean Classic 9000 if:

  • You prefer a more streamlined, no-frills brushing experience without the need for app integration.
  • You’re looking for an excellent cleaning performance at a more affordable price point.
  • You value longer battery life and want a brush that can go for up to 3 weeks without needing a charge.
  • You appreciate the simplicity of cycling through brushing modes using a dedicated button on the handle.

Ultimately, both models offer exceptional cleaning power and a range of features to suit different preferences. However, the DiamondClean Smart 9300 truly shines in terms of personalization, smart coaching, and tailored cleaning experiences, making it the ideal choice for those seeking a more immersive and data-driven approach to their oral hygiene routine.

Premium Plaque Control and Gum Care

One aspect that impressed me greatly about both the 9000 and 9300 is their commitment to delivering top-notch plaque control and gum care. Philips has invested heavily in research and development to create brush heads and modes specifically designed to address these crucial aspects of oral health.

With the 9000’s Deep Clean and Gum Health modes, I noticed a significant improvement in my ability to dislodge stubborn plaque and gently massage my gums, reducing inflammation and promoting overall gum health.

The 9300 takes this even further with its Premium Plaque Control and Premium Gum Care brush heads. During my testing, I found the Plaque Control head to be incredibly effective at removing up to 7x more plaque than a manual toothbrush, thanks to its specialized bristle configuration and pulsating action.

As for the Gum Care head, the ultra-soft bristles and unique tufting pattern worked wonders in gently massaging my gums without causing any discomfort or irritation. This is particularly beneficial for those with sensitive gums or a history of gum disease, as it promotes healing and helps maintain a healthy gum line.

Comparing Sonicare Models: A Buying Guide

When it comes to choosing between the DiamondClean Classic 9000 and the DiamondClean Smart 9300, there are a few key factors to consider:

Budget: The 9300 is undoubtedly the more premium option, with a higher price tag that reflects its advanced smart features and specialized brush heads. If you’re working with a tighter budget, the 9000 might be the more practical choice, offering excellent cleaning performance at a more affordable cost.

Tech Savviness: The 9300’s app connectivity and real-time feedback might be appealing if you’re someone who enjoys leveraging technology to enhance your daily routines. However, if you prefer a more straightforward brushing experience without the need for app integration, the 9000 might be a better fit.

Oral Health Concerns: If you have specific oral health needs, such as plaque control, gum sensitivity, or stubborn stains, the 9300’s specialized brush heads and tailored modes could be a game-changer. However, the 9000 still offers robust cleaning modes that can effectively address a wide range of oral care needs.

Travel Frequency: Both models come with premium travel cases, but the 9000’s longer battery life (up to 3 weeks) might be more convenient if you’re a frequent traveler or someone who tends to forget to charge their brush regularly.

Ultimately, the decision boils down to your personal preferences, oral health goals, and budget. Both the DiamondClean Classic 9000 and the DiamondClean Smart 9300 are excellent choices, but the 9300’s advanced features and personalization capabilities make it the more premium and technologically sophisticated option.

Best Practices for Brush Head Replacement

Regardless of which Sonicare model you choose, it’s crucial to replace your brush heads regularly to maintain optimal cleaning performance and protect your oral health. Here are some best practices I always recommend:

  • Replace brush heads every 3 months: Over time, bristles become frayed and worn, reducing their effectiveness in removing plaque and debris. Philips recommends replacing brush heads every 3 months, or sooner if you notice visible signs of wear.
  • Consider your oral health needs: If you have specific concerns like gum sensitivity or heavy staining, you might benefit from switching to a specialized brush head (like the Gum Care or Premium White options) more frequently.
  • Check for discoloration or deformation: Even before the 3-month mark, keep an eye out for discolored or severely deformed bristles, which can indicate it’s time for a replacement.
  • Use genuine Philips replacement heads: While third-party options may be tempting, I strongly advise against using non-genuine brush heads, as they might not be designed to work optimally with your Sonicare brush and could potentially damage the device.

By following these simple guidelines, you’ll ensure that your Sonicare toothbrush continues to deliver the best possible cleaning performance, safeguarding your oral health and preserving the longevity of your investment.

Importance of Pressure Sensor and Timer Features

One aspect that sets both the DiamondClean 9000 and 9300 apart from many other electric toothbrushes is their inclusion of pressure sensors and timer features. These may seem like small details, but they play a crucial role in promoting good brushing habits and preventing potential damage to your teeth and gums.

Pressure Sensors: During my testing, I found the pressure sensors to be incredibly useful in correcting my brushing technique. It’s easy to get overzealous and apply too much pressure when brushing, which can lead to enamel abrasion and gum recession over time.

Both the 9000 and 9300 feature built-in pressure sensors that alert you when you’re brushing too hard, either through a pulsating sensation or a visual indicator (depending on the model). This real-time feedback helps you adjust your brushing pressure, ensuring a gentle yet effective clean.

As someone who has witnessed the consequences of aggressive brushing firsthand, I cannot stress enough how valuable this feature is in preserving your oral health over the long term.

Timer Features: Another common issue I’ve encountered is people not brushing for the recommended two minutes per session. It’s easy to get distracted or misjudge the time, leading to an incomplete clean.

Both Sonicare models address this with their timer features. The 9000 features a Smartimer that automatically turns off the brush after two minutes, while the 9300 utilizes a Quadpacer to signal when it’s time to move
