The 9900 Prestige and DiamondClean 9000 are both state-of-the-art rechargeable toothbrushes that boast an array of impressive features. However, some distinct differences might sway your choice.

Brush Head Tennique iSense vs Bluetooth Technology

In my ten years in the dental research and industry, particularly focusing on oral gadgets, I’ve handled and tested a multitude of electric toothbrush models. Among these are the Sonicare 9900 Prestige and the DiamondClean series by Philips. One striking contrast between these two is their connecting technologies: iSense, incorporated in the 9900 Prestige, and the conventional Bluetooth in the DiamondClean series.

The 9900 Prestige’s iSense technology is a real game-changer. Leveraging my expertise, I can affirmatively say that this tech in the new Sonicare 9900 Prestige offers a more personalized brushing experience, as it mirrors the user’s brushing technique in real time.

On the other side, we have the Bluetooth technology in the DiamondClean, a feature also found in the competing Oral-B io Series 9. While not as innovative as the iSense, the Bluetooth tech in the DiamondClean smart still makes this rechargeable toothbrush among the best electric toothbrushes in sync with smartphone applications for real-time feedback.


In my years of reviewing and researching dental gadgets, I’ve come across a plethora of electric toothbrushes. Yet, two models have particularly caught my eye: the Philips Sonicare 9900 Prestige and the DiamondClean Smart 9000. The Philips 9900 Prestige, as the name suggests, emanates an air of elegance with its sleek handle design and matte finish.

This gadget feels comfortable in your hand, a feature I’ve realized is quite important for consistent usage. Philips Sonicare has clearly utilized its experience in the industry to ensure this model is as user-friendly as possible.

The DiamondClean Smart 9000, on the other hand, takes a different approach to design. While it still maintains landmark Philips Sonicare design aspects, it provides users with multiple color options, delighting customers who love to match their devices with their bathroom decor.

I’ve tested this electric toothbrush personally and found that it fits as comfortably in your hand as the 9900 Prestige does. Both toothbrush designs display a clearly visible mode button, making shifts between brushing modes a total breeze.

In my opinion, user-friendliness is where these brands outshine others, truly demonstrating how intuitive an electric toothbrush can be. Each model also features a smartphone app that provides real-time feedback on your brushing technique, an innovation I am grateful to have encountered in my ten-year-long research journey.

Brush heads

The Philips Sonicare 9900 Prestige comes equipped with an all-in-one brush head. This is a fantastic feature that I find particularly helpful in my practice. It streamlines the brushing process by allowing various brushing modes – like clean, white, and gum health – without having to switch brush heads. I cannot emphasize enough how beneficial this is for gum health.

On the other hand, the Philips Sonicare DiamondClean 9000 comes with multiple brush heads. These include the Plaque Defence brush head for exceptional cleaning, the Gum Care brush head for gentle cleaning along the gum line, and the Whitening brush head for removing surface stains.

Having handled and tested these brush heads, I can attest to their effective cleaning power. Moreover, the Sonicare app provides real-time feedback which is an impressive sensor feature of both these models.

Now, let’s talk about traveling. I remember once when a patient asked me, “Doc, what toothbrush is best for traveling?” I couldn’t help but chuckle as I had just the answer. The Philips Sonicare 9900 Prestige and the DiamondClean 9000.

They both come with stylish travel cases, protecting your brush handle and brush heads while also working as a charger. A handy feature, especially when you’re on the go.

It’s fascinating how Oral-B also provides effective cleaning with an emphasis on gum health. However, in my research, I’ve been consistently impressed with Philips’ SenseIQ technology for its intuitive adjustments to pressure, speed, and brushing motion.

Furthermore, the all-in-one brush head of the Prestige 9900 has made scrubbing a breeze, supporting gum health while delivering a thorough clean.

We’ll dive more into SenseIQ and other features in subsequent sections of this article. So stay tuned and continue reading to make an informed decision about which electric toothbrush suits your oral care needs the best.

Glass vs USB Charger

Breaking it down, the DiamondClean 9000 is charged using a glass charger, which is a unique proposition by Philips and is perfect for those who prioritize elegance and minimalistic design. In contrast, the all-in-one Sonicare 9900 Prestige trades the glass charger for a handy USB charging travel case, focusing more on utility and convenience for users who often find themselves on the move.

The DiamondClean Smart 9700 boasts a pressure sensor that effortlessly integrates with a smart-phone app allowing real-time feedback on your brushing technique, while the 9900 Prestige has a scrubbing sensor that detects over-enthusiastic brushing and helps retract excess pressure automatically. Both brush models prioritize gum health and adaptive care during a brushing session, maintaining a clean mode that adjusts according to your brushing style and pressure to optimize plaque removal.

In my over ten years of experience in dental research, I’ve handled and tested various models of what are arguably the best electric toothbrushes in the market, and these two stand out in terms of deep cleanability.

  • In both models, you notice when you apply too much pressure, for example, thanks to the real-time pressure sensing feature. Gone are the days of raw gums and leftover plaque after a brushing session.
  • From a design point of view, the 9900 series sports a sleeker, more modern look with its single power button, while the DiamondClean Smart 9700 maintains a classic feel with multiple clean mode buttons on display.In conclusion, both brushes showcase the direction the future of oral health is headed; prioritizing adaptive gum health features, plaque detection, and ease of use. It’s fantastic witnessing how much of an impact such advancements have on improving dental hygiene globally, contributing to fewer dentist visits and ultimately happier smiles. Over the years, it’s been a pleasure walking this journey with you and helping to shed a light on the best products the dental world has to offer.

Cleaning Performance

Who knew that the differences between two toothbrush models could be so pronounced? Conceding the first point to the premium electric toothbrush, the 9900 Prestige clearly takes the trophy in terms of battery life. With only one charge, this Sonicare brush remarkably purrs away for weeks, generously minimizing your interaction with the charger base. This feature definitely swings a positive mark for the 9900 Prestige in this review.

Speaking from the perspective of someone who has been knee-deep in dental research for more than a decade, much pressure is often a deterrent to optimal oral health. Imagine my delight when I tested Prestige toothbrush – it was the perfect balance.

The comparison to the Oral-B IO Series 9 was inevitable, given its reputation. During testing, I discovered the Philips Sonicare App on my smartphone app signaled if there was too much pressure – a brilliant aspect for users who want real-time feedback. This prestigious toothbrush seemed like a forerunner in the race against the diamond clean offering, an impression reaffirmed by my affinity for the Philips charger base. Elaborating, the charging base conveniently doubles as a sturdy stand, saving you valuable counter space – an often underappreciated feature if you ask me!

Real-time guidance with SenseIQ vs post-brush app feedback

The Philips Sonicare 9900 Prestige stands apart with its game-changing SenseIQ technology which ensures a bespoke cleaning experience tailored to your brushing style. Now, what does this mean for you? There’s such a thing as ‘too much pressure’ when brushing, often leading to gum damage.

Trust me, in my tenure of researching dental gadgets, I’ve seen countless cases where using too much force causes more harm than good. The 9900 Prestige’s SenseIQ technology identifies when you’re brushing too hard and alerts you, making it a premium electric, rechargeable toothbrush that cares about preserving your oral health.

The DiamondClean 9000, on the other hand, provides feedback via the Sonicare app but only after your brushing session. In my opinion, real-time feedback by the 9900 Prestige’s SenseIQ is way more beneficial. It’s like having a dental professional overseeing your brushing session, preventing you from doing any inadvertent damage.

The DiamondClean’s style of brush is also something to note. Instead of the Prestige’s A3 premium all-in-one brush head, it includes multiple heads for different purposes. You’ve got to learn why these Diamondclean brush heads are beneficial.

But from my perspective, having a quality all-in-one brush head like the A3 Premium which efficiently covers all areas is a more convenient option than having to switch between multiple heads. The choice, ultimately, is yours, depending on your personal preferences. So, go ahead, charge the toothbrush up and give it a whirl! The thing with dental hygiene is, you never know what works best until you give it a try.

All-in-One vs multiple brush heads

When the 9900 Prestige launched, it was the finest toothbrush tech Philips Oral Healthcare had to offer. It felt like Philips products leveled up with an all-purpose brush head, an innovation that Sonicare calls the “All-in-One”.

Designed to maintain optimal teeth and gums health, my experiments certainly put them up there with the best. Now, let’s chat about the cost. The 9900 Prestige comes with a tag of $399.99, a bit heavy, I agree, but considering the features, it’s worth every penny in my opinion.

On the other hand, purchasing multiple brush heads is a familiar practice with models like the DiamondClean 9000. I found during my research, it can be an advantage as each brush offers targeted cleaning. Conveniently, if you are lost like Amazon in a forest of choices, the Sonicare app presents tailored advice on how to better use the brush to clean your teeth. Comparatively, the DiamondClean 9000 is well designed and might edge the competition against some rivals, sans Oral-B electric toothbrushes. This brings a twist to the plot, doesn’t it? But hey, that’s what healthy competition is all about!

Which delivers the ultimate clean?

Coming from my decade-long experience as a dental operative as well as my keen personal interest in oral hygiene technology, it is, in my opinion, the Philips Sonicare 9900 Prestige that takes the crown as the premium toothbrush.

The exceptional SenseIQ technology it boasts means it adjusts to the way you brush. It’s not so much of a scrubbing action as it is a professional-grade, personalized dental care treatment. Throw the issue of irritating your gums or applying too much pressure out of the window, this toothbrush nips those problems in the bud.

Its sleek elegant design also easily makes it an executive toothbrush and when it comes to brushing intensities, this model lets you pick your preference with ease. The button on the handle? It’s right there at the bottom of the handle, it couldn’t be any more convenient!

The Philips DiamondClean 9000 are no slouch in their performance either. It’s like an underdog story but featuring electric brushes. It offers the best value in comparison the 9900 Prestige model when considering the basics. The visual pressure sensor to warn you if you are brushing too hard makes it a sure pick for sensitive and gum health categories.

Plus, it comes with multiple brush heads so you could easily switch around depending on your specific needs, so you’re not just confined to one option. The way this brush comes with an intuitively designed travel case, a glass charger and USB charging option, you would be hard-pressed to pick a suitable place to place your brush when you aren’t using it. Of course, it’s subject to change without notice, but in the oral care universe, these details pretty much seal the deal.
