It cleans just as well as the 6100 because they both run on the same patented sonic cleaning technology that makes 62000 movements (31000 brush strokes per minute) which whips your toothpaste into bubbles that sweep between the teeth to fight hidden plaque. For basic cleaning, the 4100 will give you good results but if you want more; like massaging your gums or whitening your teeth the 6100 is the obvious choice.

5100 vs 6100 Sonicare ProtectiveClean comparisonOur Recommendation

The 6100 has variable settings and three cleaning modes which in total gives you six customization settings to tackle every aspect of cleaning your mouth including massaging your gums on gum care mode paired with a low-intensity setting, whitening, plaque removal and more.

It is feature rich with premium quality. In terms of being a high-end product, it is definitely in that bracket of high-end Sonicare models and will, of course, provide you with more options than the 5100. However, for day to day cleaning and tackling problem areas like cleaning your gums, the 5100 is just as good albeit without all the premium features (variable setting) available in the 6100.

When it comes to choosing, it all comes down to you. What is it that you need in a toothbrush?  If it is decent brushing experience, then 5100 is good for you but if you want more customization and to take things a notch higher, then the 6100 is for you.


So what are the Similarities between Sonicare Protective Clean 4100, 5100 and 6100

Both have a pressure sensor. This is a new feature that Sonicare was not keen on for a long time. However, feedback from the market has forced them to introduce it in their models. They started with the high range Sonicare FlexCare Platinum in 2016 that had an intuitive (not visible-only shown through an app) pressure sensor. In 2017 they introduced a visible pressure sensor ring in the new DiamondClean Smart range 9300,9500 and 9700. In 2018 the new Sonicare Protective Clean models 4100,5100 and 6100 both have a pressure sensor.

They all have the similar design, sleek, smooth with a matte finish. Unlike Oral B they have no rubber grip but are yet slip-free even when handled with water. Of course, the Protective clean 5100 gum health and 6100 whitening have cleaning mode and intensity settings on the handle which the 4100 does not have but the overall look and feel are more or less the same.

  • The other similarity between the Protectiveclean range is that they all have Brush Sync. The brush sync is a technology that alerts you when your brush head is due for renewal. A microchip installed in the handles triggers the LED Light to flash to remind you that you need to change the brush head. Generally for a brush head to perform at its optimum level, it needs to be replaced after 3 months use. The brush Sync because it is quite easy to forget. As you know, a won out brush is not effective in keeping your teeth healthy.

  • The RFID microchip is installed in both the 4100, 5100 and 6100. However, in the case of the 4100 the microchip only serves the purpose of reminding you to change your brush bush. As for the 5100 and 6100 the microchip serves a dual purpose. It also intuitively pairs the brush head with the recommended brush head for effective cleaning.
  • The RFID microchip is quite insightful in the sense that is you brush two times in a day, the brush Synch will alert you to swap the brush head after 3 months. If you only brush once a day the microchip will not trigger the LED light in 3 months but in 6 months. In the case that you brush 3 times a day or brush longer than the recommended two minutes per day twice a day, the reminder will come on even before you hit 3 months. The microchip keeps a log on how often the brush is used as you use it. Once you reach the calibrated 3 months usage, the LED light will flash to signal you to replace your brush head.

  • All the models have a dual charging battery that supports both 100v and 240 volts so they can be charged on USA sockets and anywhere else in the world without a voltage adapter. In case you travel abroad, all you need is a compatible plug adapter that fits into the sockets to charge your toothbrush.
  • They all have LED battery indicators. Green solid light indicates that the battery is fully charged.

All in all, the protective clean is a fresh introduction by Sonicare which now embraces having a pressure sensor on their brushes. The 4100, 5100 and 6100 are adequate for general cleaning and will definitely leave your teeth plaque free and improve your gum health. As already mentioned these models are water resistant and can be rinsed using tap water.

Overall the protective clean modes are gentle and effective to use. The 4100 is the most cost-effective because it’s relatively cheap and still gives you quality cleaning sessions that will keep your oral hygiene in top condition. If however, you need to go an extra step and whiten your teeth or pay greater attention to the health of your gums then the 6100 and 5100 are preferable. The 6100 allows you to vary the intensity to what you feel most comfortable with. For instance, having the optimum white mode on high intensity will give quicker results in whitening your teeth. Similarly, someone with sensitive teeth may prefer low intensity with the gum care brush head and mode on for optimal performance. The 6100 is the most premium of the protective range.

For high-end premium features and comfort, the DiamondClean is a clear winner because it has features like 3D mouth mapping and more cleaning modes to make your cleaning session more comfortable.

Sonicare series 2 vs. Protectiveclean 4100

As already mentioned the 4100 is an improved version of the Series 2. These two models use the same brush head, the ProtectiveClean.

Sonicare FlexCare vs. Protective clean

Philips Sonicare Flexcare is one of Sonicare’s premium toothbrushes. It was the first model by the manufacturer to have a pressure sensor albeit via an app. The Protectiveclean model that can meaningfully be compared Flexcare is the 6100 and a little bit with the 5100.

These two have quite some similarities: They all run on Sonicare’s patented sonic technology that makes 62000 movements per minute as you brush your teeth.

They both have a pressure sensor.

They both have a traveling case and dual voltage system. They can run on both 110v and 240v and therefore can be recharged anywhere in the world using the right socket plug.

The Flexcare plus comes with two brush heads (pro-results for plaque control and gum Health for gum care). The Flexcare platinum comes with two Intercare brush head that improving your gum health.

The protective clean 5100 has BrushSync technology that tracks how long you have used the brush and reminds you to buy a new one. It also automatically pairs your brush head with the appropriate cleaning mode for optimum results.

Our recommendation

On the balance of features and overall results, the Flexcare Platinum trounces the protective clean 5100 because it has more cleaning modes. It comes with two brush heads and more cleaning 4 cleaning modes compared to 3 in the 5100. The FlexCare has Bluetooth that will coach to brush your teeth better. The FlexCare Platinum has a UV sanitizer.

Brushing too hard can affect the health of your gums.

Sonicare healthy White vs Protectiveclean

  • The Protectiveclean mode that fairly compares with Sonicare HealthyWhite is the 5100 and 6100.
  • Of course, there are features that the HealthyWhite shares with the protective clean mode and these are:
  • The 6100 and Sonicare HealthyWhite both have variable settings of low, medium and high that may be used to customize the brushing experience.
  • Both the HealthyWhite and the protective clean 5100 and 6100 improves gum health in two weeks
  • They both employ the sonic cleaning technology that is proven to remove more plaque than any manual toothbrush.
  • They all have long-lasting batteries that are Lithium based that have two color (green and amber) battery indicators.
  • They both come with a traveling case for convenient parking when traveling.

Key Differences between Sonicare HealthyWhite vs Protectiveclean 5100 and 6100

Perhaps the main difference is that the Protectiveclean 5100 and 6100 has a pressure sensor that helps to protect your gums from brushing too hard.

The HealthyWhite comes with hygienic caps and a traveler’s case while the Protectiveclean 5100 and 6100 only come with a standard traveling case.

HealthyWhite features only two cleaning modes (clean and white) while the 5100 and 6100 have three cleaning modes (gum case, clean and white).

The HealthyWhite comes with a DiamondClean brush head which is one of the best whitening brush head while the 5100 comes with the optimal gum care brush head and the 6100 comes with a white that is designed to whiten your teeth.

The Protectiveclean has the BrushSync feature that automatically pairs the brush head

Our recommendation

Though the HealthyWhite has compelling features like more brushing settings (3 variable settings of low medium and high in addition to the two cleaning modes of white and clean) the protective clean has an edge over it because it has a pressure sensor and BrushSync that automatically syncs the brush head with the appropriate cleaning mode for effective cleaning. The BrushSync also intuitively tracks how long you have used your brush head to remind you to replace it. Given that the HealthyWhite is 20 dollars more expensive than the protectiveclean, then it follows that the ProtectiveClean provides more value for money.

Sonicare ProtectiveClean 4100 vs. 5100 vs. 6100 Comparison with Oral B

Well, the new improved mid-range Sonicare 4100, 5100 and 6100 seems to be an attempt by Sonicare to capture the mid-range electric toothbrush market. It could be argued that Sonicare probably has a greater market share of the high range market given how well its flagship premium toothbrush; DiamondClean is doing in the market.

Sonicare ProtectiveClean 4100 vs. 5100 vs 6100 Analysis

The new Sonicare 4100, 5100 and 6100 are improved versions of the current mid-range price models by Sonicare. For instance it the Sonicare Protective clean 4100 is an improved version of the Sonicare 2 series, the Protective clean 5100 is a revamped version of the Sonicare 3 Series gum control while the 6100 protective clean is a modified version of Sonicare HealthyWhite. The protective clean range has new features designed to match similar mid-range models by its main competitor Oral B.

Sonicare has not expressly called the protective clean models improved versions of current models in the market partly because some of their mid-range models like 2 Series and 3 Series are currently selling quite well and command a decent market share which Sonicare would not like to lose. However as an expert who has been reviewing Oral B and Sonicare models for ages. This is my hunch.

All mid-range Oral B models from the Oral B 1000, Oral B 3000, 4000 and Oral B 5000 have pressure sensors, LED light indicators, inbuilt timers, and quadpacer. They are also customized to cater for different conditions like the Oral B 3000 has gum care, sensitive teeth and daily clean. Some of these features like pressure sensor are not in Sonicare mid-price models. These new models are a direct response to these features that seemingly give Oral B an edge in the mid-priced electric toothbrush market.


Why should you choose the Protectiveclean 5100 over Oral B 3000


As always the battle between Oral B and Sonicare is never ending so its inevitable to consider how the protective performs in relation to comparatively similar toothbrushes from the Oral B range.

The Protectiveclean 5100 could be compared to Oral B 3000. These two have a pressure sensor.

Oral B has three cleaning modes (gum care, white and clean) just like the 5100. The thing that separates these two is the battery life and the Brush Sync feature present in the 5100 that automatically pairs a brush head to the right mode. Sonicare models have a longer battery life compared to Oral B. The manufacturer says the 5100 has a battery life of 14 days; however out testers got 28 days battery life on the 5100 (brushing for 2 minutes two times a day) after only one charge.

Our View and Verdict

Since these two have more or less the same features, the Sonicare 5100 has an edge over Oral B 3000 because in addition to all the features the Oral B 3000 has, the 5100 has a longer battery life of 14 days compared to the standard 7 days battery life in most Oral B toothbrushes. It also has Brush Sync feature that intuitively pairs any brush head to the appropriate cleaning mode for maximum cleaning efficiency and a travel case. The 5100 has LED light forThe Oral B has no travel case but offers Bluetooth connectivity. On the balance of all these features, the 5100 offers benefits like long battery life and traveling case that provide more value for money.
